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:
The purpose of this option is provide a way for the ASan dylib
to be loaded via `dlopen()` without triggering most initialization
steps (e.g. shadow memory set up) that normally occur when the
ASan dylib is loaded.
This new functionality is exposed by
- A `SANITIZER_SUPPORTS_INIT_FOR_DLOPEN` macro which indicates if the
feature is supported. This only true for Darwin currently.
- A `HandleDlopenInit()` function which should return true if the library
is being loaded via `dlopen()` and
`SANITIZER_SUPPORTS_INIT_FOR_DLOPEN` is supported. Platforms that
support this may perform any initialization they wish inside this
function.
Although disabling initialization is something that could potentially
apply to other sanitizers it appears to be unnecessary for other
sanitizers so this patch only makes the change for ASan.

On Myriad RTEMS, we don't need to treat the main thread differently.
The existing thread hooks will do the right thing, so get rid of all
the unneeded special logic.

Reset shadow memory during exit. Also update a cut-and-paste comment,
and do some minor refactoring of InitializeShadowMemory.
