Alexander Potapenko 7e1c51988d [TSan] Move the /proc/self/maps parsing logic to sanitizer_common 
Provide a generic way for the tools to generate memory profiles from contents of /proc/self/maps

Peter Collingbourne ffaf2eac4d [nolibc] Move all platforms to internal_getpid. 
Before, we had an unused internal_getpid function for Linux, and a
platform-independent GetPid function.  To make the naming conventions
consistent for syscall-like functions, the GetPid syscall wrapper
in sanitizer_posix.cc is moved to sanitizer_mac.cc, and GetPid is
renamed to internal_getpid, bringing the Linux variant into use.

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).

Alexander Potapenko f8109dd0f8 [libsanitizer] Unmapping the old cache partially invalidates the memory layout, so add 
a flag to skip cache update for cases when that's unacceptable (e.g. lsan).

Evgeniy Stepanov f7f616ba66 Quick fix data/bss detection in TSan. 
The old way breaks when a module's bss is adjacent to the [heap] vm area.
Both ways are not very reliable, though.

Alexey Samsonov 51ae983718 [Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).
