[asan,tsan] introduce sanitizer_common/sanitizer_defs.h and perform some renaming in asan rt. More to come.

Naming is hard. If you can suggest a better name for the directory -- speak up.

Clients may define the __asan_default_options char string containing the default options for the tool now.

When the flag is set to zero, we do not check for errors in malloc_usable_size.
This may be useful to work around a bug in Nvidia drivers prior to 295.*

per-thread stacks for signal handling. This allows to print more verbose error reports
for stack overflows.

At the moment, asan internal Printf() uses %l modifier for printing
values of size_t and related types. This works, because we control
both the implementation of Printf and all its uses, but can be a
little misleading.

This change adds support for %z to Printf(). All callers that print
sizes and pointers as integers are switched to %zu / %zx.

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.
