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.

Evgeniy Stepanov e1caa4ac72 [asan] Support running without /proc
Summary:
This patch lets ASan run when /proc is not accessible (ex. not mounted
yet). It includes a special test-only flag that emulates this condition
in an unpriviledged process.

This only matters on Linux, where /proc is necessary to enumerate
virtual memory mappings.

Kamil Rytarowski a14b908381 Switch sanitizer_procmaps_bsd to internal_sysctl
Summary:
Stop using directly sysctl(3) routines in sanitizer_procmaps_bsd
and replace it with internal_sysctl().

This will allow to install interceptors for sysctl(3).
