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.

fix_stack_using_bpsyms.py locates a .sym file based on file name only, not uuid or full path,
which causes a failure if a duplicate leaf file name is introduced. This patch introduces a
small utility program on mac and linux to extract a breakpad guid from a shared library or
executable to identify the correct symbol file when this ambiguity occurs. A subsequent commit
implements this for windows.

A new configure option --with-devtools (which sets MOZ_DEVTOOLS) is added to
control whether all DevTools, just the server, or no DevTools are included.
This defaults to just the server.
Applications should also include /devtools within their moz.build tree, so that
DIST_SUBDIR is in effect for all DevTools files if it is used by the app.
The configure option has explicitly thrown an error for more than a year now,
and it happens that the remaining way to still forcefully use it has been
broken for more than 8 months.
This step resumes shipping client and server DevTools components to the correct
products, and is enough for "mach build" to complete successfully.

Now all regular child processes, including preallocated, are deprivileged.
Only Nuwa needs uid 0, because each of its children has a different uid/gid.
