38ee0be4d1 Update Rust demangling to use rustc-demangle
The rust-demangle-capi crate hasn't been updated since 2016 and
out-of-date. Instead, Breakpad needs to use C API offered by the
rustc-demangle to demangle Rust symbols.

*** TESTING ***

1) Set up rustc-demangle

> git clone https://github.com/rust-lang/rustc-demangle.git
> cd rustc-demangle
> cargo build -p rustc-demangle-capi --release

2) Breakpad

> ./configure --with-rustc-demangle=<path to rustc-demangle>
> make check src/common/dward_cu_to_module

09b056975d fix pointer style to match the style guide
We do this in a lot of places, but we're inconsistent.
Normalize the code to the Google C++ style guide.

f2679262ac Avoid calling demangler for non-C++ symbols on Linux
Bogus demangler warnings should be suppressed on both Mac and Linux
platforms, so there is no reason to keep this filter behind __APPLE__ gate.

2ffe116322 mac: Don’t try to demangle non-C++ symbols with the C++ demangler
On Mac a C++ symbol has 1-4 underscore characters followed by a 'Z'.
Symbols that do not have this format (such as plain C symbols)
causes a lot of warnings to be printed.

2ecb2baba8 Don't demangle Rust symbols by default, but allow linking to rust-demangle.
The Rust compiler uses GCC C++ name mangling, but it has another layer of
encoding so abi::cxa_demangle doesn't produce great results. This patch
changes dump_syms to dump unmangled names by default so that consumers can
demangle them after-the-fact.

It also adds a tiny bit of support for linking against a Rust library I wrote
that can demangle Rust symbols nicely:

7398ce15b7 Initial support for dumping DWARF corresponding to Swift code
The DWARF data for Swift code has a top-level DW_TAG_module DIE as the
child of the DW_TAG_compile_unit DIE and the parent of the
DW_TAG_subprogram DIEs that dump_syms uses to locate functions.
dump_syms needs to process DW_TAG_module DIEs as introducing nested
scopes to make it work with Swift.

This also reworks demangling to be language-specific, so that the C++
demangler isn't invoked when processing Swift code. The DWARF data for
Swift code presents its mangled names in the same form as used for C++
(DW_AT_MIPS_linkage_name or DW_AT_linkage_name) but the mangling is
Swift-specific (beginning with _T instead of _Z). There is no
programmatic interface to a Swift name demangler as an analogue to C++'s
__cxa_demangle(), so mangled Swift names are exposed as-is. Xcode's
"xcrun swift-demangle" can be used to post-process these mangled Swift
names on macOS.

Support for mangled names presented in a DW_AT_linkage_name attribute,
as used by DWARF 4, is added. This supersedes the earlier use of
DW_AT_MIPS_linkage_name.

The Linux symbol dumper's classes are reasonably portable, and should be

their unit tests. Update #include directives and Makefile.
