Running rustc with an open fd 4 sometimes causes it to fail with an obscure
error when it tries to connect to a job server on that fd. Closing the fd
solves the problem.
close_fds does what we need, and is the default value in Python 3, but not
in Python 2.

Bug 1282866 removed the only configuration where it did something.
Since then, using it only leads to a configure error.

Currently, --enable-lto just implies --enable-linker=lld, which
essentially only works on Linux, and assumes one can't do lto with
anything other than lld. Which is not true. As a matter of fact, even
ld.bfd can do lto, as long as the gold plugin for llvm is available,
or when doing lto with GCC instead of clang.
Anyways, to allow more lto setups, we adapt the --enable-linker setup
to:
- work on macOS, which it currently doesn't, and add support for the mac
linker (ld64), which, unfortunately, doesn't have a clean way to be
detected, so work around that.
- default to lld if lto is enable, no linker was explicitly given, the
compiler is clang *and* the build target is not macOS.

LineIO currently attempts to convert bytes to unicode using the
system preferred encoding. This can obviously fail for some byte
sequences.
In many cases, the conversion is happening for purposes of logging.
In these cases, Unicode validation shouldn't be that important to
us.
So, this commit teaches LineIO to accept an argument defining its
Unicode error mode. We also teach relevant users of LineIO doing
logging to switch the default mode from "strict" to "replace" so
invalid Unicode byte sequences can be logged with the Unicode
replacement character.
During review, glandium pointed out that it may make better sense
to defer Unicode decoding to the logging layer instead of in LineIO.
I agree with this idea. But it can be implemented in another bug:
for now we should unbust the build system.

Often you only want to evaluate a function if all its dependencies
are true. Expressing this in a "when" can be difficult. So let's
add a convenience decorator for it.
The existing code for @depends_if() was refactored to take an
evaluation function as its first argument. This prevents some
duplicate code and turns @depends_if() and @depends_all() into
one-liners.

The values that we need to find in the registry can be inconsistent across
different installations, so we retrieve values from both views in our search
for a valid SDK. This also ensures this works for 32-bit and 64-bit python.
And include code to work around a bug on older Python versions.

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.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

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 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.
