Update the vendored third-party dependencies for the mozjs-sys crate.
This picks up recent bug-fixes and reduces noise in unrelated runs
of 'mach vendor'.
The libc crate is also used by the rust url parser.
gcc 0.3.35 -> 0.3.40
libc 0.2.16 -> 0.2.18
libz-sys 1.0.6 -> 1.0.10

This patch also drops the pretense that rust-url-capi will be used from
outside of c++, or that it will be used outside of mozilla-central,
removing the ifdef __cplusplus code, and including the C++ header
"nsString.h".

In our current Rust world, we have the following dependency structure:
xul.so --------------------------+
|
xul-gtest.so -+--> xul.a --------+-> gkrust
|
+--> gkrust-gtest
This structure results in link errors with multiply-defined symbols
between gkrust-gtest and gkrust with newer Rust releases when linking
xul-gtest.so. So we have to do something different.
Our new structure is:
xul.so --------------------------+
|
xul-gtest.so -+--> xul.a --------+-> gkrust --+-> gkrust-shared
| |
+--> gkrust-gtest --------------+
and we enforce that a given shared library can only have at most one
Rust library that it depends on. Said Rust library is assumed to
include all significant Rust dependencies of the dependent static
libraries as well. (In the above structure, gkrust is simply a wrapper
around gkrust-shared, so gkrust-gtest doesn't have to include gkrust as
a dependency.)
This patch removes the memory usage tracking in the script that wraps the
linking of the xul library. This patch also generalizes the wrapping of the
xul linking process to all platforms.

When building gtest libxul with LTO, the fact that
StaticXULComponentStart is not passed first to the linker makes the
linker pull the NSModule symbols out of all the other objects first,
presumably because linking the gtest objects (which appear first) pulls
code from the other non StaticXULComponent* objects first.
So, to make things link properly with LTO, we trick the build system
to always put StaticXULComponentStart first.
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.

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.
