We need to let ContentParent and PluginModuleParent get a reference to the ProfileGatherer
during the window of time that we're profiling so that if they start to die (the actor is
starting to go away), they have a gatherer they can send their last profile data to.
This makes it clearer that really it's the same thing as FINAL_TARGET,
with preprocessing.
We still keep DIST_FILES in backend.mk because it's shorter and doesn't
really matter.
tools/power/rapl.cpp:844:5 [-Wunreachable-code] code will never be executed
clang reports a -Wunreachable-code warning for sigemptyset() because Darwin's sigemptyset() is a macro that always returns 0. Thus `if (sigemptyset(&sa.sa_mask) < 0)` is always false and `Abort("sigemptyset() failed")` is never called. Linux's sigemptyset() can return 0 or -1. The extra parens around (0) suppress the clang warning.
Now, running |mach doc <path/to/project>| will generate the sphinx based docs of the project and open them
in the default browser. Mulitple doc paths can be supplied at a time. E.g:
./mach doc testing/mozbase
The Read the Docs environment doesn't have SHELL defined. This causes
mach.mixin.process's import to fail, as it insists on finding an active
shell. While we could fix mach.mixin.process to not raise if the
variable is not set, this is a bit more work and has wider build system
and mach implications. So we employ a quick hack instead.
DONTBUILD (NPOTB)
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

Various bits depend on RefPtr.h to provide RefCounted<T> and RefPtr<T>.
It will be easier to manage an automatic conversion from RefPtr<T> to
nsRefPtr<T> if we split out the dependency on RefCounted<T> first.
This commit renames ProfileEntry::set{Js,Cpp}Frame methods to
ProfileEntry::init{Js,Cpp}Frame to highlight the fact that they are intended to
initialize the entry, and that setting other flags should happen after one of
these calls.
