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.

* frida-asan: Implement leak detection

* Fix merge issues

* Rebased on dev to get llmp/shmem changes; Clippy fixes

* Add FridaOptions struct

* Add the Custom ExitKind; Get rid of Clone/PartialEq on ExitKind

* Make it possible to recover from an ASAN error

* Add SIGTRAP to crashing signals

* Add back (conditional) crashing on Asan errors.

* Fix too-large immediates in add instruction

* Implement RcShMemProvider, finally fix the EOP bug

* Clear ASAN_ERRORS before each test

* Fix warnings; Fix review issues

* Cleanup prints

* Add timeout to Frida mode

* Make allocation-/free-site backtraces optional

* CPU Context and backtrace (on android/aarch64 atm) on crash

* Make stalker conditional

* Add metadata to solution, and write metadata files

* Add addresses to backtrace; Add reporting of ASAN stack errors; Fix ASAN reporting bugs

* Remove meaningless backtrace on crash

* Fix the x0, x1 load in report

* use upstream color-backtrace

* use __builtin_thread_pointer instead of custom asm

* Don't unwrap ASAN_ERRORS if it isn't some

* Fix bug where we weren't clearing the drcov basicblocks after each run

* Fix bug where we were dropping an ashmem too soon

* Fix OwnedPtr instead of CPtr

* Fix gettls for all archs

* cfg guards for target arch, disabling Frida-ASAN/-DrCov if not on aarch64

* Cargo fmt

* Only panic in options when asan/drcov are turned on; Merge fixes

* gothook only supported on unix

* Fix gettls on msvc

* Another attempt to fix MSVC gettls

* Fix backtrace use

* nostd fixes; warning fixes

* formatting

* Migrate FridaEdgeCoverageHelper into libafl_frida, and rename to FridaInstrumentationHelper

* Clean up uses

* Move DrCovWriter to libafl_targets

* Refactor DrCovWriter to get a vec of DrCovBasicBlocks; formatting

* Update to newer backtrace which supports android with gimli

* windows fixes
