Peter Collingbourne 6f4be19b57 [nolibc] Change internal syscall API to remove reliance on libc's errno. 
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.

Sergey Matveev 954c6ef10f [sanitizer] Move GetThreadStackAndTls from TSan to sanitizer_common. 
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).

Evgeniy Stepanov 517118e6b4 [sanitizer] Sanitizer __internal_*stat interface. 
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().

Timur Iskhodzhanov 664ec5d7a8 Finally drop the 'static' from INLINE and ALWAYS_INLINE 
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

Chandler Carruth 2b3c00eec7 Revert r179012: "[msan] Intercept glob()." 
This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).

Alexander Potapenko 32efd25b93 [libsymbolized] If we can't find an address in the list of shared libraries, try to reload it. 
Add a regression test for the case where such behavior helps TSan:
  1. race is reported in the main module
  2. new shared library is loaded
  3. race is reported in the shared library

Kostya Serebryany 5b4267f7e7 [sanitizer] found a bug by code inspection: CHECK(a=b) instead of CHECK(a==b). Was puzzled why lint did not catch it. Turns out this check was disabled for asan source. fix all cases and enable the check
