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.

Summary:
Host symbolizer & stacktraces related code in their own RT:
`RTSanitizerCommonSymbolizer`, which is "libcdep" by nature. Symbolizer &
stacktraces specific code that used to live in common files is moved to a new
file `sanitizer_symbolizer_report.cc` as is.
The purpose of this is the enforce a separation between code that relies on
symbolization and code that doesn't. This saves the inclusion of spurious code
due to the interface functions with default visibility, and the extra data
associated.
The following sanitizers makefiles were modified & tested locally:
- dfsan: doesn't require the new symbolizer RT
- esan: requires it
- hwasan: requires it
- lsan: requires it
- msan: requires it
- safestack: doesn't require it
- xray: doesn't require it
- tsan: requires it
- ubsan: requires it
- ubsan_minimal: doesn't require it
- scudo: requires it (but not for Fuchsia that has a minimal runtime)
This was tested locally on Linux, Android, Fuchsia.

Summary:
This is a pure refactoring change. It just moves code that is
related to filesystem operations from sanitizer_common.{cc,h} to
sanitizer_file.{cc,h}. This makes it cleaner to disable the
filesystem-related code for a new port that doesn't want it.
Submitted on behalf of Roland McGrath.

In this diff, I define a general macro for defining weak functions
with a default implementation: "SANITIZER_INTERFACE_WEAK_DEF()".
This way, we simplify the implementation for different platforms.
For example, we cannot define weak functions on Windows, but we can
use linker pragmas to create an alias to a default implementation.
All of these implementation details are hidden in the new macro.
Also, as I modify the name for exported weak symbols on Windows, I
needed to temporarily disable "dll_host" test for asan, which checks
the list of functions included in asan_win_dll_thunk.

Summary:
At this point SANCOV_OPTIONS are not functional but it is our intent
to move here sanitizer coverage flags from various sanitizers _OPTIONS.
