Some compilers on some platforms by default #define some of the values
we're using in the source we use in get_compiler_info(). Namely,
mingw-gcc #defines WINNT by default, and the WINNT in the source is then
replaced by 1, breaking the check.
The C preprocessor, fortunately, doesn't expand macros inside C strings.
So instead of `%KERNEL WINNT`, we output `%KERNEL "WINNT"`, and strip
out the double quotes. For good measure, we do this for all values in
the source used in get_compiler_info().

Update linux32 tooltool manifest to use a gecko build of rustc and cargo
for x86_64-unknown-linux-gnu host targeting both x86_64 and i586.

Pass --target i585-unknown-linux-gnu when building for 32-bit linux.
We mostly want this for official builds, but Debian needs it too,
in both cases to support old machines without SSE2 instruction set
support, so while it means developers will have to `rustup target add
i585-unknown-linux-gnu` when building for this architecture that is
not a common task (most linux devs will be on 64-bit) and it reduces
variance and surprise if binaries are distributed.

This required implementing a utility function to resolve the binary
type. I used GetBinaryTypeW via ctypes because this seems the fastest.
I arbitrarily limited the function to testing 32-bit and 64-bit Windows
executables because hopefully those are the only executables we'll
ever encounter. We can expand the binary detection later, if needed.
This includes support for running on non-Windows platforms.

We want to ensure that our automation builds don't pull in libraries
from crates.io, and we need --frozen support in cargo to do that. If we
don't have that support, we shouldn't build.
The base compiler check in python configure does some preprocessing,
which ensures the compiler works to some extent. Autoconf used to have
a more complete test, doing a compile/link. We do have plenty of tests
afterwards that do that anyways, but it's better if we fail early if
the toolchain fails somehow.
This refactors try_compile such that the *_compiler variable themselves
can be used to trigger compiler tests. Eventually, we'll want something
similar for preprocessing and possibly other invocations.
This also removes similar tests from build/autoconf/toolchain.m4.

This patch is really two separate changes.
The first change is that rust crates are large, standalone entities that
may contain multitudes of source files. It therefore doesn't make sense
to keep them in SOURCES, as we have been doing. Moving to use cargo
will require a higher-level approach, which suggests that we need a
different, higher-level representation for Rust sources in the build
system.
The representation here is to have the build system refer to things
defined in Cargo.toml files as the entities dealt with in the build
system, and let Cargo deal with the details of actually building things.
This approach means that adding a new crate to an existing library just
requires editing Rust and Cargo.toml files, rather than dealing with
moz.build, which seems more natural to Rust programmers. By having the
source files for libraries (and binaries in subsequent iterations of
this support) checked in to the tree, we can also take advantage of
Cargo.lock files.
The second is that we switch the core build system over to building via
cargo, rather than invoking rustc directly.
We also clean up a number of leftover things from the Old Way of doing
things. A number of tests are added to confirm that we'll only permit
crates to be built that have dependencies in-tree.
Until now, HAVE_64BIT_BUILD was entirely determined by a compiler check.
But we didn't run the check on e.g. artifact builds, while relying on
its result for some non-compilation related things, leading to subtle
discrepancies.
This changes the configure check to derive HAVE_64BIT_BUILD from bitness
determined by the target CPU, and double checked with a compiler check.

Now that check_prog, through find_program, returns paths that the build
system can handle, we don't need MT to just be "mt.exe".
However, we still need the PATH to be altered for the other tools we're
not checking in python configure yet (e.g. midl). We also still need
PATH altered for the compiler itself, because for e.g. the amd_x86
version, a necessary DLL is in the amd directory, which means PATH
always needs to be altered for cl.exe.
This is hopefully more reliable than parsing just the summary line,
and makes available other keys like the commit-hash which we'd like
to pass to the debug symbol automation.
Note that the commit-hash field will have the value 'unknown' for
builds not made out of upstream git. So the key is available with
official and gecko rust builds, but not for example the current
Debian-packaged rustc.

Before bug 1289294, the impossibility to find the version of MT was only
issuing a warning. Warnings in configure are essentially useless, so
since we weren't and still aren't doing anything with the result of that
check, and since there are versions of MT that don't print out a version
number, just remove the check.

Until now, it's not been possible to do something as straightforward as:
option('--foo', default=delayed_getattr(milestone, 'is_nightly'))
The reason is that option's default needs what it's given, if it's a
@depends function, to depend on --help.
But we can't have every delayed_getattr add dependencies on --help,
because that would make unwanted things to depend on --help and run
when displaying the help.
Until we can totally remove --help dependencies, this change makes the
resulting @depends function created by delayed_getattr depend on --help
if the @depends function it's given already depends on --help.
The mozconfig detection logic has bitten us on many occasions in the
past. The following changes are made to tentatively improve the
situation:
- The API is modified such that autodetection of the mozconfig has
to be a conscious decision made by the caller, and not triggered
any time there is no mozconfig given, which could be a conscious
decision of the opposite.
- mozinfo.json now stores the actual mozconfig (or lack thereof) used
during configure.

Before bug 1269513, yasm_version returned a Version object, and it
doesn't anymore, which made the assignment of _YASM_*_VERSION skipped
silently.
Then, configure would go through the yasm version checks as if they were
false and skipping over the AC_MSG_ERRORs, printing out:
/builds/slave/try-m64-0000000000000000000000/build/src/old-configure: line 19615: test: : integer expression expected
which is why this went undetected: the version checks were simply
ignored.
Some shells, however, evaluated the yasm version checks as true, hitting
the AC_MSG_ERRORs.
For most cases, this replaces a value that was set in a way that would ignore
an environment variable, so this restores behavior for values that were
set in confvars.sh.

We were unconditionally adding them, now actually check what the
compilers default to and add the flags if they are necessary.
This will, in the future, allow finer grained policy changes, where
we can decide that C++11 and C++14 are fine, downgrading compilers
that do C++17, etc.
At the same time, allow to enable jemalloc 4 with --enable-jemalloc=4.
MOZ_JEMALLOC4 will be deprecated later.
This also changes the semantics for freebsd, where the system jemalloc
is used, relying on MOZ_MEMORY being unset (default on freebsd) and
MOZ_JEMALLOC4 to be set. In this new setup, MOZ_JEMALLOC4 implies
--enable-jemalloc=4, which still works because of the corresponding
changes to old-configure.
While forgetting about it was warned about, having to add every new
environment option to wanted_mozconfig_variables is cumbersome. It turns
out there is a hackish way to make things work without that list, which,
all things considered, is not worse than the hacks around the
wanted_mozconfig_variables function, and are certainly an improvement as
it doesn't require an ever growing list of environment options.
At the same time, we improve things slightly by deriving HOST_CC from CC
in a smarter way, as well as CXX from CC, which we weren't doing
previously.
Many related things are not moved at the same time to keep the patch
somehow "small".
So far, everything was essentially executed at "declaration". This
made the sandbox code simpler, but to improve on the tooling around
python configure (for tests and introspection), we need to have more
flexibility, which executing everything at declaration doesn't give.
With this change, only @depends functions depending on --help, as
well as templates, are executed at the moment the moz.configure
files are included in the sandbox. The remainder is executed at the
end.

Because closing the handler is not enough (it eventually reopens
itself), the dumping of config.log overwrites the file, and confuses
the process of reading it to dump it in the first place, showing
incomplete logs. The intent from the start was that nothing would be
logged in the FileHandler, so on top of closing it, actively remove it.
When reading config.log, with old-configure output, we may get non-ascii
strings, but that currently fails because we're using plain open() to
read it. So use encoded_open() instead (which does the same job for
other files in the same script).
Because the build system can be encapsulated in mach, python configure
can have a pipe as stdout/stderr, and in that case, sys.stdout/stderr
have an ascii encoding, failing to print out anything that doesn't
fit in ascii, consequently failing to print the things we've read from
config.log. So reopen stdout and stderr with the right encoding in
the configure output handler.
Gonk, Android, and the generic cross-compilation setup all were using a
different yet similar way to prefix the toolchain. The latter was even
wrong, since the target and target alias usually don't match actual
toolchain prefixes (which don't include the machine part of the target).
Note that this removes force-setting cross_compiling to yes in
old-configure, which wasn't working because every AC_TRY_COMPILE
resets it with $ac_cv_prog_cc_cross or $ac_cv_prog_cxx_cross.
The initial goal of templates was to provide a way to write shorter
constructs for some generic tasks during configure. But the limitations
of the sandbox and the properties of templates made them used for more
general functions.
Consequently, this led to templates having to be available from
anywhere, which, in turn, led to difficult to introspect constructs.
With bug 1257823, we've made almost everything use set_config and
similar functions from the global scope, but we don't enforce that
those primitives are only used at the global scope.
This change does that: it enforces that primitives are only used at
the global scope. Or in templates.
Now, since templates were used for other purposes than generic uses
of other primitives, we now allow non-template functions to be declared.
Those can be used everywhere, but don't have access to the sandbox
primitives.
So far, we've been using the lowercase of the variable name, but it's
not enough for some special cases. Those special cases could do their
own business, but then, they'd have to duplicate 90% of check_prog,
which is less desirable.
While DummyFunction is descriptive of what the instances are (and they
can't even be called), the various uses of isintance(obj, DummyFunction)
are kind of confusing, especially when they are in moz.configure land
(and this bug is about to add another one).
And since the file is also used for old-configure, close our handle on
the file before spawning old-configure, and make old-configure append
there instead of truncating the file.
The reason the "checking" string always appears is that @depends
functions are always called, regardless of the value of the dependency.
This introduces a new decorator @depends_true, which works like
@depends, but the decorated function is not called unless one of the
dependency value resolves to True.
The new decorator can also be used to replace many cases where we do
@depends(foo)
def bar(foo):
if foo:
...
