[ASan] Move the SIGSEGV/SIGBUS handling to sanitizer_common
...
This change is a part of refactoring intended to have common signal handling behavior in all tools.
This particular CL moves InstallSignalHandlers() into sanitizer_common (making it InstallDeadlySignalHandlers()), but doesn't enable default signal handlers for any tool other than ASan.

sanitizers: Make sure Visual Studio gets error reports
...
Visual Studio appears to close stderr before launching a non-console
win32 program. This means we don't see any sanitizer reports. If
stderr printing fails, call OutputDebugStringA to get the reports into
the Visual Studio debugger console.

[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.

[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.

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).
