Peter Collingbourne b69b8a4a8f [nolibc] Move GetPageSize to the individual platforms. 
GetPageSize wraps sysconf(_SC_PAGESIZE) on POSIX platforms, but
sysconf resides in libc.  To make this libc-independent on Linux,
move the wrapper to sanitizer_mac.cc and return the Linux-specific
constant EXEC_PAGESIZE in the sanitizer_linux.cc implementation.

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).

Alexander Potapenko d895ae94f9 Use 64-bit inodes in file operations. ASan is now built with -mmacosx-version-min=10.5, thus the default inode 
size is 32 bits. However the supported client code is going to target 10.6 and higher, where 64-bit inodes will be used.

Alexander Potapenko 1746f555ee Add a libsanitizer API __sanitizer_sandbox_on_notify(void* reserved), which should be used by 
the client programs to notify the tools that sandboxing is about to be turned on.

Alexander Potapenko 7811425843 Add caching to the MemoryMappingLayout class on Linux. This is necessary for the cases when a sandbox prevents ASan from reading the mappings 
from /proc/self/maps.
The mappings are currently being cached on each access to /proc/self/maps. In the future we'll need to add an API that allows the client to notify ASan about the sandbox.

Alexey Samsonov 961276af26 [Sanitizer] Extend a symbolizer code. Implemented for Linux only. Use dl_iterate_phdr to get virtual addresses of mapped module sections.
