Evgeniy Stepanov a59459de27 [asan] Fix a flaky test.
This test has a chance to hit some other random allocation
and get neither heap overflow nor SEGV.

Relax test condition to only check that there is no internal CHECK failure.

If not, return 0 to avoid infinite loop of DTORs (in case of use-after-free). Calls to this function will be inserted by clang (separate change)

Alexey Samsonov 91bb8e0e3a Generalize sanitizer allocator public interface.
Introduce new public header <sanitizer/allocator_interface.h> and a set
of functions __sanitizer_get_ownership(), __sanitizer_malloc_hook() etc.
that will eventually replace their tool-specific equivalents
(__asan_get_ownership(), __msan_get_ownership() etc.). Tool-specific
functions are now deprecated and implemented as stubs redirecting
to __sanitizer_ versions (which are implemented differently in each tool).

Replace all uses of __xsan_ versions with __sanitizer_ versions in unit
and lit tests.

Kostya Serebryany cd60ed53f6 [asan] when reporting an ODR violation, also print the stack traces where the globals have been registered (thus show the name of shared library or exe to which the global belongs). The reports become a bit too verbose but I do not see any *simple* way to make them more compact. This should be especially helpful when the ODR happens because the same .cc file is used twice in the project in differend DSOs

Evgeniy Stepanov fe18102649 [sancov] Handle fork.
Reset coverage data on fork().
For memory-mapped mode (coverage_direct=1) this helps avoid loss of data
(before this change two processes would write to the same file simultaneously).
For normal mode, this reduces coverage dump size, because PCs from the parent
process are no longer inherited by the child.

This feature has been working quite well so far, found a few bugs and zero false positives. The main problem is that there could be lots of true positives and users will have to disable this checking until the bugs are fixed.

Evgeniy Stepanov 567e516015 [asancov] Write coverage directly to a memory-mapped file.
This way does not require a __sanitizer_cov_dump() call. That's
important on Android, where apps can be killed at arbitrary time.

We write raw PCs to disk instead of module offsets; we also write
memory layout to a separate file. This increases dump size by the
factor of 2 on 64-bit systems.

Sergey Matveev 6cb47a083b [sanitizer] Support sandboxing in sanitizer coverage.
Summary:
Sandboxed code may now pass additional arguments to
__sanitizer_sandbox_on_notify() to force all coverage data to be dumped to a
single file (the default is one file per module). The user may supply a file or
socket to write to. The latter option can be used to broker out the file writing
functionality. If -1  is passed, we pre-open a file.

Sergey Matveev 76e02e90c5 [ASan] Fix coverage behavior when a PC belongs to an unknown address range.
This happens, e.g., when coverage data is collected for a module which is then
dlclose()'d. Currently this causes CovDump() to ignore all PCs that are greater
than the unrecognized PC. In other words, unloading a module causes ASan to
silently ignore any coverage data for modules loaded at higher addresses.
Instead we should just skip the unrecognized PCs.
