[PATCH] D58184: [scudo][standalone] Introduce platform specific code & mutexes

[Kostya Kortchinsky via Phabricator via llvm-commits]

Herald added projects: LLVM, Sanitizers.

This CL adds the platform specific code for Fuchsia, Linux & Android,
as well as some tests related to those (more tests to come later).
While some of it is pretty much a straight port of the existing scudo &
sanitizer_common code, the memory mapping functions have been reworked
a bit to fit the limited usage scenario that Scudo has for them.

For Fuchsia, I can now track the Vmar/Vmo pair for memory mappings if
there is an intent to grow or decommit some mapping (that will be
useful for the Primary).
