- Building is nightly channel only. Beta and release for Fennec 58 don't build
stylo. It means that the package size for 58 beta/release isn't incremented
by this change.
- The preference for stylo is still turned off Nightly 58. It will be turned on
59 after fixing some bugs for crashtests and etc. Our target to enable stylo
for Android is 59.
- ./mach bootstrap already installs clang etc to build stylo and bindgen.
Developers for mobile won't require additional build options for this change.

Stylo's recent enabled-by-default behavior, combined with some Linux
distributions's packaging of LLVM separately from Clang, causes
confusion. To allay such confusion, rearrange the configure checks to
do two things:
1) Check for the clang binary prior to checking for clang's shared
libraries; it should be more obvious what you need to install from
an error about clang, and installing clang should pull in the
necessary clang libraries, avoiding the following scenario:
- run configure
- get error message about libclang
- install libclang
- run configure
- get error message about clang
2) Provide some context for what to do to avoid this error; the user may
not understand why we need a separate C/C++ compiler when they already
have a perfectly suitable one on their system.
These were only enabled for b2g nightly builds, which we no longer
support, so these are unnecessary checks. The supporting code was
removed in bug 1396158.

The `os` dereference here is only used in the error message,
and using it in the conditional tree doesn't really help
readability since it's too short; the target prefix is
helpful.

This patch removes the ability to select which protocols you want
included in necko, a wholly untested configuration that is broken in
practice. We have no need of this kind of configurability in necko.
In addition, this removes the final vestiges of rtsp support, which was
originally removed in bug 1295885 but still had some stuff hanging
around behind some ifdefs (that were never true).

Making more decisions on behalf of developers:
L10NBASEDIR is always defined, if not specified, it's ~/.mozbuild/l10n-central,
or in MOZBUILD_STATE_PATH/l10n-central if the state path in defined in the
environment.
If a locale isn't checked out, do that. The targets for which that works are
merge-%, installers-%, langpack-%
But only do that for Nightly builds, as for Beta and beyond, we have
explicit revisions to use for the builds, and we don't want to break release
builds silently with this.

Build Stylo (the styling system from servo) by default in all
builds for win32, win64, macOS and linux64 targets. It was
previously enabled for automation builds, so this just changes
the behaviour for local developer builds.
Note that this introduces a new dependency on libclang for the
binding generator. If you're developing on a tier-1 platform,
run `./mach boostrap` to install a working copy. Otherwise
llvm+libclang 4.0.1 is recommended.
Remove the explicit --enable-stylo=build in mozconfig.stylo
in favour of the configure default.
Add mozconfig.stylo to the hazard and debug-asan mozconfigs
so LLVM_CONFIG is defined properly for those builds.
Based on a patch by Bobby Holly in bug 1356991.

We've had trouble with crashes and hangs on macOS with
libclang builds from tooltool, so for local developer
builds we prefer the homebrew or macports packages
installed by `mach bootstrap`.
However, we were searching ~/.mozbuild before the homebrew
directory, resulting using the wrong libclang when developers
had run `mach bootstrap` before the switch, or anyone who
had used `mach artifact toolchain` on macOS.

"value" here is a PositiveOptionValue, which behaves like a tuple.
Its __eq__ fails if the types of the operands aren't the same. A
string literal isn't a PositiveOptionValue, so the "value == 'build'"
check always fails. This meant that --enable-webrender=build was
always being interpreted as --enable-webrender. Yikes.

Since Homebrew doesn't automatically place clang and associated binaries
on PATH, we need to do the task ourselves. MacPorts does place the
binaries in PATH, but uses yet another name, so we have to add that to
the search list.
Add the dependency between "MOZ_ENABLE_SKIA_PDF" and "MOZ_TREE_FREETYPE" on Windows:
- let |tree_freetype| returns true if |skia_pdf| returns true on Windows, and
- avoid defining "MOZ_ENABLE_CAIRO_FT" on Windows ("cairo-ft-font.c" includes <dlfcn.h>, which only exists on posix platforms)

llvm-config on Windows can return a path for the clang binary which does
not end in ".exe", which then causes failures when attempting to check
for the existence of the file. Rather than attempting to simply tack
".exe" onto the file if it's not already there, delegate to
moz.configure's `find_program` function, which will take care of that
case and several others besides.
The libclang test wants to find a libclang library for use for rust bindgen.
But that's a host process, that needs a host libclang. However, we
currently only have the target library/object prefix/suffixes. This
works fine... except when cross-compiling.
So we need to figure out the proper ones for the host, and use those
instead. For that, we templatize library_name_info in order to get a
separate set of library/object prefix/suffixes for the host and the
target.
And we use the host set for the libclang check.
Ideally, the build system would also use the host set for host tools
builds, but we'll leave that to a followup.

The function as it currently is matches how things were done in
old-configure.in. However, that's just confusing and hard to follow. In
fact, the unit test failing numerous times while writing this patch
pretty much highlights the problem.
So instead of a confusing set of overrides to the prefixes and suffixes,
spell out the whole set for each set of platforms. This also happens to
make the function shorter. Win/win.
At the same time, we normalize the function output as a nested
namespace, where we get, for each of dll, lib, import_lib, etc. a
prefix/suffix pair. Further down the road, we can imagine changing those
to class instances with a method allowing to format file names based on
those prefix/suffixes.

This option causes MOZ_USE_SYSTRACE to be defined. The only use of that is in
GeckoProfiler.h where it causes the PROFILER_PLATFORM_TRACING macro to set
android::ScopedTrace. But android::ScopedTrace was defined in widget/gonk/
which was recently removed, so this won't work any more.
Furthermore, all that android::ScopedTrace did was to do a pair of
atrace_{begin,end}() calls, which doesn't seem that useful.
For ease of use, we want to make checks for llvm-config automatically
examine the directory where `mach bootstrap` would install things, so
users don't necessarily have to have a mozconfig when building stylo.
Since the computation of this value is non-trivial, we pull out the
whole list of possible names for llvm-config into a @depends function,
and insert the computed value into that list when necessary.
It seems like when we get (lib)clang_path from a --with-(lib)clang-path option
it has type PositiveOptionValue. If we pass that directly to os.path.exists or
os.path.isdir we will get:
TypeError: coercing to Unicode: need string or buffer, PositiveOptionValue found
This patch makes us unwrap those values before passing them.
Ideally this check will alert people that something is wrong with their
configuration. This check shouldn't normally be firing with our `mach
boostrap` setup, but if somebody chooses to install distribution
packages for some reason, this will at least prevent some problems.
People building without a compilation environment (artifact builds, l10n
builds) won't have a compiler available, let alone the bits to build
bindgen. We should limit our checks for bindgen-y things accordingly.
Prior to this patch, we had a not-so-great hack in place: the bit of
configure that determined bindgen config paths *and* the bit of
configure that returned various pieces of information about Stylo were
both guarded on --enable-stylo-build-bindgen. We should really only
have one place that depends on --enable-stylo-build-bindgen, and this
patch puts us in a place to do that, by making bindgen_config_paths
properly use a when= argument to determine when it needs to run.
This commit makes the `stylo` function entirely redundant, and said
function will be removed in the next patch.
stylo.build is just a copy of stylo_config.build, so we should use the
former to limit the number of duplicate concepts we have. Using
stylo_config consistently enables us to separate out what artifact
builds need vs. non-artifact builds.
On some systems, llvm-config may be installed, but not the files to
which it needs to refer. We should ensure that the values returned
actually make some sense.
--with-libclang-path is supposed to be a directory, and
--with-clang-path is supposed to be a file, but it was easy to pass a
directory for the latter, and it was easy to misinterpret the
documentation for --with-libclang-path as pointing to one of the
libraries themselves. Clearer documentation and additional checks
should help with this situation.
The argument passed to the function is a PositiveOptionValue,
which represents its option values as a tuple. The __eq__ for
this type first compares type() of the operands. Since the
previous code compared a PositiveOptionValue to a string
literal, this always failed. There's possibly room to
improve the behavior of PositiveOptionValue. But for now,
let's rewrite stylo_config() so it works.

If we don't do this, various bits of test infrastructure will turn on
when stylo is merely built, not enabled, which will cause no end of
orange and unhappiness.
