Vitaly Buka d4abe9e7d3 [sanitizer_common] Move filesystem-related code out of sanitizer_common.cc
Summary:
This is a pure refactoring change.  It just moves code that is
related to filesystem operations from sanitizer_common.{cc,h} to
sanitizer_file.{cc,h}.  This makes it cleaner to disable the
filesystem-related code for a new port that doesn't want it.

Marcos Pividori 8650f5d1a1 General definition for weak functions
In this diff, I define a general macro for defining weak functions
with a default implementation: "SANITIZER_INTERFACE_WEAK_DEF()".
This way, we simplify the implementation for different platforms.

For example, we cannot define weak functions on Windows, but we can
use linker pragmas to create an alias to a default implementation.
All of these implementation details are hidden in the new macro.

Also, as I modify the name for exported weak symbols on Windows, I
needed to temporarily disable "dll_host" test for asan, which checks
the list of functions included in asan_win_dll_thunk.
