Mike Hommey 1ad733c5c4 Bug 1474871 - Link dump_syms against rustc-demangle. r=ted
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.
