[ASan] Change activation strategy.
...
Now ASan deactivation doesn't modify common or ASan-specific runtime
flags. Flags stay constant after initialization, and "deactivation"
instead stashes initialized runtime state, and deactivates the
runtime. Activation then just restores the original state (possibly,
overriden by some activation flags provided in system property on
Android).

[ASan] Introduce AllocatorOptions to configure allocator behavior.
...
Summary:
Reduce the dependency of allocator code on runtime flags. Instead,
pass a bunch of options that configure allocator behavior at
initialization or re-initialization. That would allow us to
cleaner modify allocator behavior during a program execution
when ASan is activated or de-activated.

[ASan] Re-structure the allocator code. NFC.
...
Introduce "Allocator" object, which contains all the bits and pieces
ASan allocation machinery actually use: allocator from sanitizer_common,
quarantine, fallback allocator and quarantine caches, fallback mutex.
This step is a preparation to adding more state to this object. We want
to reduce dependency of Allocator on commandline flags and be able to
"safely" modify its behavior (such as the size of the redzone) at
runtime.

Relocate the external headers provided by ASan and the common sanitizer
...
library.
These headers are intended to be available to user code when built with
AddressSanitizer (or one of the other sanitizer's in the future) to
interface with the runtime library. As such, they form stable external
C interfaces, and the headers shouldn't be located within the
implementation.
I've pulled them out into what seem like fairly obvious locations and
names, but I'm wide open to further bikeshedding of these names and
locations.
I've updated the code and the build system to cope with the new
locations, both CMake and Makefile. Please let me know if this breaks
anyone's build.
The eventual goal is to install these headers along side the Clang
builtin headers when we build the ASan runtime and install it. My
current thinking is to locate them at:
<prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h
<prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h
<prefix>/lib/clang/X.Y/include/sanitizer/...
But maybe others have different suggestions?
Fixing the style of the #include between these headers at least unblocks
experimentation with installing them as they now should work when
installed in these locations.
