Teresa Johnson 8f778b283d [sanitizer_common] Add facility to get the full report path
Add a new interface __sanitizer_get_report_path which will return the
full path to the report file if __sanitizer_set_report_path was
previously called (otherwise it returns null). This is useful in
particular for memory profiling handlers to access the path which
was specified at compile time (and passed down via
__memprof_profile_filename), including the pid added to the path when
the file is opened.

There wasn't a test for __sanitizer_set_report_path, so I added one
which additionally tests the new interface.

Pratyai Mazumder 73812f3d0b [SanitizerCoverage] Add `__sanitizer_cov_bool_flag_init` as the weak interface functions.
Summary:
Following up the discussion on D77638 (and following rGd6cfed6060c283dc4a6bf9ca294dcd732e8b9f72
as example), defining `__sanitizer_cov_bool_flag_init` as the weak interface
functions in various compiler-rt/ files.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Matt Morehouse 52fd169035 [libFuzzer] Report at most one crash per input.
Summary:
Fixes https://github.com/google/sanitizers/issues/788/, a deadlock
caused by multiple crashes happening at the same time.  Before printing
a crash report, we now test and set an atomic flag.  If the flag was
already set, the crash handler returns immediately.
