From now on we allow the clients to override signal handlers set by ASan, but print a warning in such a case.

Remove the tests for signal() and sigaction(), because they made little sense even without this change.

Introduce __asan_set_error_report_callback() to allow the client program post-process the error reports.
If the callback is set, Report() and Printf() print the reports into a buffer (together with stderr), which is then passed to the client.

where memcpy() in fact aliases memmove() and thus calling it with
overlapping parameters is not an error.

These should fix the output tests on Mac.

Normally this function should not create copies of constant strings, but it does when the default CFAllocator
is replaced (e.g. under AddressSanitizer)

This test is related to http://code.google.com/p/address-sanitizer/issues/detail?id=10

[asan] workaround for bug http://llvm.org/bugs/show_bug.cgi?id=11763. Do not bark on memcpy(a, a, size).
