[Sanitizer] Unify summary reporting across all sanitizers.
...
This change unifies the summary printing across sanitizers:
now each tool uses specific version of ReportErrorSummary() method,
which deals with symbolization of the top frame and formatting a
summary message. This change modifies the summary line for ASan+LSan mode:
now the summary mentions "AddressSanitizer" instead of "LeakSanitizer".

Overhaul the symbolizer interface.
...
This moves away from creating the symbolizer object and initializing the
external symbolizer as separate steps. Those steps now always take place
together.
Sanitizers with a legacy requirement to specify their own symbolizer path
should use InitSymbolizer to initialize the symbolizer with the desired
path, and GetSymbolizer to access the symbolizer. Sanitizers with no
such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for
initialization.
The symbolizer interface has been made thread-safe (as far as I can
tell) by protecting its member functions with mutexes.
Finally, the symbolizer interface no longer relies on weak externals, the
introduction of which was probably a mistake on my part.

[ASan] Enforce the memmove semantics for both memcpy() and memmove() interceptors on Darwin.
...
Due to bugs in the interposition of resolver functions on 10.7 and 10.8 both memcpy() and memmove()
were previously intercepted by INTERCEPTOR(memcpy), which led to false positives and crashes (see http://llvm.org/bugs/show_bug.cgi?id=16362 )
We choose to use a memmove-like function in both cases. This effectively disables the overlap checks in memcpy(), but the overlaps
aren't possible in practice, because memcpy() and memmove() are the same function on Darwin.
Once the interposition is fixed in 10.9, we'll need to revisit this issue, see https://code.google.com/p/address-sanitizer/issues/detail?id=226

Fix a veritable conucopia of bugs in the readdir_r interceptors.
...
First, the reason I came here: I forgot to look at readdir64_r which had
the exact same bug as readdir_r. However, upon applying the same
quick-fix and testing it I discovered that it still didn't work at all.
As a consequence, I spent some time studying the code and thinking about
it and fixed several other problems.
Second, the code was checking for a null entry and result pointer, but
there is no indication that null pointers are viable here. Certainly,
the spec makes it extremely clear that there is no non-error case where
the implementation of readdir_r fails to dereference the 'result'
pointer and store NULL to it. Thus, our checking for a non-null 'result'
pointer before reflecting that write in the instrumentation was
trivially dead. Remove it.
Third, the interceptor was marking the write to the actual dirent struct
by looking at the entry pointer, but nothing in the spec requires that
the dirent struct written is actually written into the entry structure
provided. A threadlocal buffer would be just as conforming, and the spec
goes out of its way to say the pointer to the *actual* result dirent
struct is stored into *result, so *that* is where the interceptor should
reflect a write occuring. This also obviates the need to even consider
whether the 'entry' parameter is null.
Fourth, I got to the bottom of why nothing at all worked in readdir64_r
-- the interceptor structure for dirent64 was completely wrong in that
it was the same as dirent. I fixed this struct to be correct (64-bit
inode and 64-bit offset! just a 64-bit offset isn't enough!) and added
several missing tests for the size and layout of this struct.

Fix a bug in the readdir_r interceptor: when we reach the end of the
...
directory stream, the entry is not written to, instead *result is set to
NULL and the entry is not written to at all.
I'm still somewhat suspicious of the correct instrumention here --
I feel like it should be marking the written range as the pointer in
*result and the length (*result)->d_reclen in case the implementation
decides not to use the passed-in entry (if that's even allowed).
Finally, the definition of 'struct dirent' analog used in the
interceptor is wrong in 32-bit mode with _FILE_OFFSET_BITS=64 as it hard
codes the use of a pointer-sized offset.
I've added a somewhat goofy test for the bug I fixed via ASan --
suggestions on how to better test the interceptor logic itself welcome.

Call __asan_free_hook() before marking the chunk quarantinned
...
Summary:
With this change, the user may safely call __asan_get_ownership()
from malloc/free hooks and assume it would return "true". If there is a
realloc/free race, free hook might be called twice, but I think it's acceptable,
as it's a data race and would later be reported anyway.
This change also fixes a bug when failing realloc incorrectly marked the
original memory as "quarantinned".

Disable init-order checking before destructors are run.
...
We don't want to report initialization-order bugs when a destructor of a global
variable accesses dynamically initialized global from another
(not necessarily initialized) module. We do this by intercepting __cxa_atexit and
registrering our own callback that unpoisons shadow for all dynamically initialized
global variables.

[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] Begin moving sanitizer_common's libc-dependent code to a separate library

Introduce a new object library, RTSanitizerCommonLibc, which will contain
the subset of sanitizer_common with libc dependencies. RTSanitizerCommon
contains the remainder of sanitizer_common, and is intended to have no
libc dependencies. Begin moving code to RTSanitizerCommonLibc, starting
with sanitizer_common.cc, whose libc-dependent portion is moved to
sanitizer_common_libcdep.cc, the first member of the new library.
This split affects the CMake build only. The makefile build continues
to produce the full sanitizer_common library.
