Adrian Herrera 4034d0ce20 [libFuzzer] Fixed description of fuzzer merge control file. 
Summary:
The description of the fuzzer merge control file appears to be incorrect/out of date.
No "DONE" line appears in the control file. Rather, FT and COV are the markers that appear
following the STARTED line.

Kostya Serebryany f762a11544 [libFuzzer] introduce an experimental mode -fork=1, where fuzzing happens in a subprocess (still running multiple inputs per process), thus making the fuzzing more resilient to timeouts and OOMs. This is just a skeleton of the code, and some associated refactoring, not a fully working feature yet.

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.

George Karpenkov 10ab2ace13 Move libFuzzer to compiler_rt. 
Resulting library binaries will be named libclang_rt.fuzzer*, and will
be placed in Clang toolchain, allowing redistribution.
