[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.

[scudo] 32-bit and hardware agnostic support Summary: This update introduces i386 support for the Scudo Hardened Allocator, and offers software alternatives for functions that used to require hardware specific instruction sets. This should make porting to new architectures easier. Among the changes: - The chunk header has been changed to accomodate the size limitations encountered on 32-bit architectures. We now fit everything in 64-bit. This was achieved by storing the amount of unused bytes in an allocation rather than the size itself, as one can be deduced from the other with the help of the GetActuallyAllocatedSize function. As it turns out, this header can be used for both 64 and 32 bit, and as such we dropped the requirement for the 128-bit compare and exchange instruction support (cmpxchg16b). - Add 32-bit support for the checksum and the PRNG functions: if the SSE 4.2 instruction set is supported, use the 32-bit CRC32 instruction, and in the XorShift128, use a 32-bit based state instead of 64-bit. - Add software support for CRC32: if SSE 4.2 is not supported, fallback on a software implementation. - Modify tests that were not 32-bit compliant, and expand them to cover more allocation and alignment sizes. The random shuffle test has been deactivated for linux-i386 & linux-i686 as the 32-bit sanitizer allocator doesn't currently randomize chunks.

[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`.
