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.

[Sanitizer] fix signed/unsigned compare warnings in sanitizer_stacktrace_test. Build sanitizer_common tests with -Werror as we use predictable just-built Clang for building them

Summary:
The test sets up fake x86-style fp+retaddr frames, since that's all the
unwinder works with.

[ASan] temporarily disable alloc_dealloc_mismatch on Mac, since the previous commit caused error reports in gTest.

Because the interceptors will reside in a dylib, not the main executable, we can't just declare them,
but must use the interposition machinery.
Fix the test expectations in large_func_test.cc affected by the change.
This CL should make our Mac buildbots green.

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.

Using > instead of >= ensures that each frame deref makes progress and
that we eventually terminate.

[ASan] Delete asan/dynamic dir and temporarily move the interposers declarations to asan_intercepted_functions.h
Now that we have only one dependency on asan_intercepted_functions.h, we can unite that code with the interceptors declarations in asan_interceptors.cc and get rid of asan_intercepted_functions.h
