Alexander Potapenko a15d49cc1f [libsanitizer] Introduce INTERCEPTOR_WITH_SUFFIX which is to be used for appending the __DARWIN_ALIAS() version suffixes to function names on Darwin. 
This should fix asan/lit_tests/wait.cc under ASan.

Kostya Serebryany f0b8f989e9 add Linux syscall wrappers and ThreadLister to sanitizer_common 
ThreadLister is a Linux-specific class for obtaining the thread IDs of a process from procfs (/proc/<pid>/task/). It will be used by leak checking code.
Also add several syscall wrappers which will be required by the same code that uses ThreadLister, but are not used in ThreadLister itself.
Patch by Sergey Matveev

Alexander Potapenko e8ba1c851a [ASan] Refactoring: nuke the redundant function declarations in asan_intercepted_functions.h 
that had been used on OS X only.
The INTERCEPTOR() macro on OS X is now responsible for declaring the wrapped function, the wrapper and the
pair of pointers to them in __DATA,__interposition section. Thus adding an interceptor requires editing a single file now.

Kostya Serebryany 07bb3925b0 [sanitizer] replace size_t with SIZE_T in interceptors (same for ssize_t, off_t and off64_t). This is done to avoid confusion and to make the code work with compilers that define size_t w/o any includes (MSVC)

Dmitry Vyukov 7fb7330469 asan/tsan: weak interceptors 
The idea isthat asan/tsan can survive if user intercepts the same functions. At the same time user has an ability to call back into asan/tsan runtime. See the following tests for examples:
asan/output_tests/interception_failure_test-linux.cc
asan/output_tests/interception_test-linux.cc
asan/output_tests/interception_malloc_test-linux.cc
