Original patch by Abdoulaye Walsimou Gaye.

This change moves to a model where the error value of a system call is
potentially contained in the return value itself rather than being
implicit in errno.  The helper function internal_iserror can be used
to extract the error value from a return value.  On platforms other
than Linux/x86_64 this still uses errno, but other platforms are free
to port their error handling to this new model.

Move this function to sanitizer_common because LSan uses it too. Also, fix a bug
where the TLS range reported for main thread was off by the size of the thread
descriptor from libc (TSan doesn't care much, but for LSan it's critical).

With this change, __internal_*stat always expect a "struct stat *" argument.
This avoids stat/stat64 caller-side confusion (sanitizer_common tests already
made this mistake), and allows the use of __internal_fstat() as a drop-in
replacement for libc's fstat().

Some flags that are common to ASan/MSan/TSan/LSan have been moved to
sanitizer_common.

This time it's the full list scavenged from syscalls.h
Fixed return value type.

The ALWAYS_INLINE doesn't have static on POSIX anyways since r178341; the INLINE is only used in .h files, so shouldn't have been 'static' in the first place

Pre- and post- hooks for linux syscalls. Not wired into anything, but exposed
