WIP: Implement ASAN instrumentation using frida (#45)
* frida_asan: Implemented initial asan runtime library

* frida_asan: Switch to hashbrown

* Implemented GOT-based hooking to isolate the hooking of the memory functions. Implemented initial ASAN instrumentation

* WIP: Shadowing all used memory. Currently tracking pages using a BTreeSet. Slow AF!

* Add SigTrap to unix_signals and inprocess

* Working frida-asan, almost no speed degradation.

Currently the shadow check is reversed, so it checks only that the shadow is not 0.
We need to implement sub-8-byte checking.

* Format

* Cleanup and formatting

* Sub-qword and 16-byte checks implemented; Fixed unaligned access to QWORD

* Pass the ucontext_t to signal handlers. Initial regdump on crash

* Fix typo

* Make the context argument a mut ref

* Add missing files; Implement initial reporting

* Refactor out gothook; Move safety checkers to dynasm

* Get rid of const assembly blobs no longer needed

* Move to a handler function instead of using SIGTRAP.

This bloats the transformed code, but doesn't seem to have a major impact on performance.

Also, implemented pretty backtraces and assembly output.

* Formatting

* Get rid of all the pinning crap I wasted my day on, We don't need it

* windows fixes

* ashmem

* ashmem_service: server side ready

* ashmem_service: client side ready. Ready for integration

* ashmem_service: changes to UnixShMem to make it 'threadable'

* ashmem_service: format

* ashmem_service: Undo changes to UnixShMem, make the thread own the AshmemService instead; Fix protocol bug

* ashmem_service: working ashmem service. Fix merge issues

* use the newly released capston e 0.8.0; Fix a nasty bug where the afl_area an pc_pointer were reversed. Changed Vectors to Boxed [u8]

* Implement type detection for reporting; Implement double-free/unallocated free checking

* fmt

* Cleanup code a little

* frida-asan: This is an omnibus commit. Should probably have been a bunch of small commits, but I don't have the time/patience.

 - Implemented DrCov support in order to debug a failing harness. This is actually
   generic and should be moved out of libafl_frida.
 - Implemented LIBAFL_FRIDA_OPTIONS env var to pass options to the frida helper,
   to dynamically enable/disable asan and drcov.
 - Implemented memory reuse - after each test case the used pages are recycled and
   can be reused in the next test case.
 - Implemented and tested vectorized instruction instrumentation.
 - Implemented not instrumenting atomic load/store instructions. The cost of
   trying to emulate their behaviour is too high at the moment.
 - Implemented probing of shadow bit to determine the best match for the current
   system.
 - Implemented shadow memory pre-mapping where it is available. We probe for this
   too.
 - Implemented ability to specify a list of modules to instrument on the command
   line. This allows fine-grained control of which modules are instrumented for
   coverage/asan/drcov.
 - Implemented unpoisoning of the Input target_bytes in a pre_exec hook.
 - Added support for zero-sized allocations. We return 0x10 bytes at the moment.
 - Added all known operator new/delete functions to hooks.
 - Added workaround for frida_gum_allocate_near bug.
 - Cleaned up reporting, added reporting for different error types.
