Fixed unicorn_dumper_gdb.py for updated version of gef (#2045)
Updated unicorn_dumper_gdb.py to support new gef api and replaced deprecated functions . The functions that are not in the new gef api are read_memory(), and current_arch(). Also replaced some deprecated functions with the updated versions of them.

    replaced read_memory() with GefMemoryManager.read() as read_memory(). read_memory() is in legacy-gef-api
    replaced current_arch with gef.arch.registers
    replaced get_process_maps() with gef.memory.maps (just depreacated)
    replaced get_register() with gef.arch.register()

Make the compiler wrapper stripping `-Wl,-no-undefined` in addition to `-Wl,--no-undefined`.
Both versions of the flag are accepted by clang and, therefore, used by building systems in the wild (e.g., samba will not build without this fix).

* Remove dead code in write_to_testcase (#1955)

The custom_mutators_count check in if case is duplicate with if condition.
The else case is custom_mutators_count == 0, neither custom_mutator_list iteration nor sent check needed.

unicornafl: Add UAF chcker to loader (#2009)
* impl uaf chcker

By adding a list of freed chunks, add the chunk to the list during free, check whether the allocated block is in the freed chunk list during malloc, and if so, remove the chunk from the freed chunk list, in __check_mem_access check whether the address is in the freed chunk list. This enables the detection of uaf.

* make uaf_check be configruable

unicornafl: fix malloc of size 0 (#2010)
* bugfix: free a chunk with a size of 0, it will cause 1 byte oob.

Malloc does not check the size. Generally, malloc(0) should return 0 but there will return two pages. Free will use is_buffer_in_chunk to check whether the address is in the chunk. At that time, the chunk.data_addr == total_size . Free pass address and "1" to is_buffer_in_chunk. So cause 1 byte out-of-bound.

Catch invalid frees (#2008)
1. There isn't a need to check all chunks when address == 0
2. If the address is not in chunks, the program may want to free an object that doesn't exist. There may be a "double-free" or "invalid-free" vulnerability. (This patch is from the repo named "Battelle/afl-unicorn")

* replaced unicornafl with unicorn

The submodule of unicorn cannot be imported through unicornafl.*_const here. If we want to use the *_const module, we should reference `from unicorn.*_const import *` like this instead of importing the entire contents of the *_const module via unicornafl。
