memory.h conflicts with a system header, so we have workarounds to
change include paths to work around this.
This is mostly a cherry-pick of this upstream commit:
8bb3d55af7
..but the patch was applied separately to toolkit/crashreporter/google-breakpad
and toolkit/crashreporter/breakpad-client since we've forked the latter,
and there's also one other fixup of a source file included.
MozReview-Commit-ID: HH92HZG7y9n
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.
