This introduces two new crates:
- jsrust, for standalone builds. This crate is compiled into a static library
libjsrust.a, which gets linked into the shared Spidermonkey library when it's
built, or into the static Spidermonkey library otherwise. This is just a
static library wrapping jsrust_shared below.
- jsrust_shared, for Gecko embedding. It just references other Rust
crates actively used in Spidermonkey. It is used to be embedded as part of
a new Rust dependency in Gecko (in gkrust).

The new version of breakpad imported in bug 1309172 doesn't demangle
rust symbols at all, contrary to before, where it tried to C++ demangle
them, which worked for many, although far from all. It however has
rust-demangle support as long as it's linked against a copy of the
rust-demangle-capi crate from https://github.com/luser/rust-demangle-capi/
This imports the code from the rust-demangle-capi crate but because of
some build system complications it's not taken as-is:
- it uses rusty-cheddar, which is deprecated, to generate a C header.
- rusty-cheddar depends on syntex_syntax, which now fails to build.
- rust-demangle-capi has crate-type staticlib, which can't be used
as a dependency in a Cargo.toml. For that reason, we can't create
a fake crate that depends on it to have it vendored.
Overall, it's only a few lines of rust, and the C header can be written
manually, so this is what we do here. The created crate is named in a way
specific to dump_syms.
The build system doesn't know how to figure out what system libraries
are required to link rust static libraries, although the rust compiler
has /some/ support to get the information, so we handle that manually.

This includes the necessary changes for the serde replacement upgrade from
WR PR 2777 as well.

For people who don't know how our Rust opt-level setup works--or for
people who did know and repeatedly forget--it would be good to have some
documentation in Cargo.toml pointing at the correct place.
