* update grammar mutator
* lto llvm 12+
* docs(custom_mutators): fix missing ':' (#1953)
* Fix broken LTO mode and response file support (#1948)
* Strip `-Wl,-no-undefined` during compilation (#1952)
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.

* Fixes to afl-cc and documentation (#1974)
* Always compile with -ldl when building for CODE_COVERAGE
When building with CODE_COVERAGE, the afl runtime contains code that
calls `dladdr` which requires -ldl. Under most circumstances, clang
already adds this (e.g. when building with pc-table), but there are some
circumstances where it isn't added automatically.
* Add visibility declaration to __afl_connected
When building with hidden visibility, the use of __AFL_LOOP inside such
code can cause linker errors due to __afl_connected being declared
"hidden".

* afl-showmap: Start a only a single fork server (#1718)
A forkserver is started by afl_fsrv_get_mapsize() when dynamically
finding the map size. When an input directory option is specified a
second fork server was also started. This commit re-arranges the inits
for several forkserver struct members so that we can re-use the server
started by the get_mapsize() call when not in coresight/qemu/unicorn
modes and just start the server otherwise.
* Source Code Coverage support for Nyx (Part 1) (#1720)

* afl-fuzz.c: Document -i - in --help (#1725)
afl-fuzz.c: Document `-i -` in `--help`, to write that `-i` can be passed '-' to resume the prior fuzzing job. Also reference AFL_AUTORESUME so users know they can set that parameter to sidestep the issue entirely.
* tritondse custom mutator attempt
* tritondse fixes
* update libnyx (#1727)

Update LLVM instructions, because versions higher than 14 are supported and to be explicit that LLD is also required

* Variable AFL_EXIT_ON_TIME description has been added.
Variables AFL_EXIT_ON_TIME and afl_exit_on_time has been added.
afl->exit_on_time variable initialization has been added.
The asignment of a value to the afl->afl_env.afl_exit_on_time variable from
environment variables has been added.
Code to exit on timeout if new path not found has been added.
* Type of afl_exit_on_time variable has been changed.
Variable exit_on_time has been added to the afl_state_t structure.
* Command `export AFL_EXIT_WHEN_DONE=1` has been added.
* Millisecond to second conversion has been added.
Call get_cur_time() has been added.
* Revert to using the saved current time value.
* Useless check has been removed.
variable AFL_USE_LSAN.
AFL_USE_LSAN introduces the macro __AFL_CHECK_LEAK() which will check
for a memory leak when the macro is run. This is especially helpful
when using __AFL_LOOP().
If __AFL_LEAK_CHECK() is not used when AFL_USE_LSAN=1 is set,
the leak checker will run when the program exits.
