Broke the QEMU sanitizer bots due to a missing header dependency. This
actually needs to be fixed on the bot-side, but for now reverting this
patch until I can fix up the bot.

[scudo] Make logging more consistent
Summary:
A few changes related to logging:
- prepend `Scudo` to the error messages so that users can identify that we
reported an error;
- replace a couple of `Report` calls in the RSS check code with
`dieWithMessage`/`Print`, mark a condition as `UNLIKELY` in the process;
- change some messages so that they all look more or less the same. This
includes the `CHECK` message;
- adapt a couple of tests with the new strings.
A couple of side notes: this results in a few 1-line-blocks, for which I left
brackets. There doesn't seem to be any style guide for that, I can remove them
if need be. I didn't use `SanitizerToolName` in the strings, but directly
`Scudo` because we are the only users, I could change that too.

[scudo] Implement stricter separation of C vs C++
Summary:
Initially, Scudo had a monolithic design where both C and C++ functions were
living in the same library. This was not necessarily ideal, and with the work
on -fsanitize=scudo, it became more apparent that this needed to change.
We are splitting the new/delete interceptor in their own C++ library. This
allows more flexibility, notably with regard to std::bad_alloc when the work is
done. This also allows us to not link new & delete when using pure C.
Additionally, we add the UBSan runtimes with Scudo, in order to be able to have
a -fsanitize=scudo,undefined in Clang (see work in D39334).
The changes in this patch:
- split the cxx specific code in the scudo cmake file into a new library;
(remove the spurious foreach loop, that was not necessary)
- add the UBSan runtimes (both C and C++);
- change the test cmake file to allow for specific C & C++ tests;
- make C tests pure C, rename their extension accordingly.

[scudo] Android build support
Summary:
Mark Android as supported in the cmake configuration for Scudo.
Scudo is not added yet in the Android build bots, but code builds and tests
pass locally. It is for a later CL. I also checked that Scudo builds as part
of the Android toolchain.
A few modifications had to be made:
- Android defaults to `abort_on_error=1`, which doesn't work well with the
current tests. So change the default way to pass `SCUDO_OPTIONS` to the tests
to account for this, setting it to 0 by default;
- Disable the `valloc.cpp` & `random_shuffle.cpp` tests on Android;
- There is a bit of gymnatic to be done with the `SCUDO_TEST_TARGET_ARCH`
string, due to android using the `-android` suffix, and `i686` instead of
`i386`;
- Android doesn't need `-lrt`.

[scudo] 32-bit quarantine sizes adjustments and bug fixes
Summary:
The local and global quarantine sizes were not offering a distinction for
32-bit and 64-bit platforms. This is addressed with lower values for 32-bit.
When writing additional tests for the quarantine, it was discovered that when
calling some of the allocator interface function prior to any allocation
operation having occured, the test would crash due to the allocator not being
initialized. This was addressed by making sure the allocator is initialized
for those scenarios.
Relevant tests were added in interface.cpp and quarantine.cpp.
Last change being the removal of the extraneous link dependencies for the
tests thanks to rL293220, anf the addition of the gc-sections linker flag.

[sanitizer] Initial implementation of a Hardened Allocator
Summary:
This is an initial implementation of a Hardened Allocator based on Sanitizer Common's CombinedAllocator.
It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast.
The following were implemented:
- additional consistency checks on the allocation function parameters and on the heap chunks;
- use of checksum protected chunk header, to detect corruption;
- randomness to the allocator base;
- delayed freelist (quarantine), to mitigate use after free and overall determinism.
Additional mitigations are in the works.
