Evgeniy Stepanov d8cc7f9f07 [hwasan] Provide __sanitizer_* aliases to allocator functions.
Summary:
Export __sanitizer_malloc, etc as aliases to malloc, etc.
This way users can wrap sanitizer malloc, even in fully static binaries.

Both jemalloc and tcmalloc provide similar aliases (je_* and tc_*).

Petr Hosek 016d18c61a [sanitizer] Make function declarations C-compatible
The public sanitizer headers are intended to be usable from either
C++ or C, but they declare no-argument functions with the syntax that
is not a proper prototype declaration in C. This goes unnoticed until
someone uses -Wsystem-headers.

Alex Shlyapnikov 028c4cddad [Sanitizers] New sanitizer API to purge allocator quarantine.
Summary:
Purging allocator quarantine and returning memory to OS might be desired
between fuzzer iterations since, most likely, the quarantine is not
going to catch bugs in the code under fuzz, but reducing RSS might
significantly prolong the fuzzing session.

Alexey Samsonov 91bb8e0e3a Generalize sanitizer allocator public interface.
Introduce new public header <sanitizer/allocator_interface.h> and a set
of functions __sanitizer_get_ownership(), __sanitizer_malloc_hook() etc.
that will eventually replace their tool-specific equivalents
(__asan_get_ownership(), __msan_get_ownership() etc.). Tool-specific
functions are now deprecated and implemented as stubs redirecting
to __sanitizer_ versions (which are implemented differently in each tool).

Replace all uses of __xsan_ versions with __sanitizer_ versions in unit
and lit tests.
