Subtly, as toolkit/moz.configure happens before toolchain tests, we
can't set MOZ_SERVO_LIBS from there. And toolkit/moz.configure is
not always included either, making things awkward to do in python
configure.
OTOH, there's only one place where MOZ_SERVO_LIBS is used, and the
corresponding setup can actually be done there (in moz.build) instead.
I think we shouldn't shy away from moving things this way.
Run the updated import script to split the in-tree byteorder
code into a separate directory and build it as a dependent crate.

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.
Current stable versions of Rust use two Rust-specific personality
routines to perform exception handling, which empirically does not play
well with the Mac linker's optimizations for using compact unwind
formats. Nightly Rust has solved this issue, but for now, we'll have to
use -no_compact_unwind to disable the linker optimization. The size
impact is negligible (0.02%) and will be going away once nightly Rust
becomes stable.
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.

netapi32's API isn't used at startup and browsing page. So netapi32 should move to delay load DLLs.

The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.

This also effectively changes how DMD is enabled from requiring both
replace-malloc initialization and the DMD environment variable to
requiring only the former. The DMD environment variable can still be
used to specify options, but not to disable entirely.
This however doesn't touch all the parts that do enable DMD by setting
the DMD environment variable to 1, so the code to handle this value
is kept.
