* changelog
* 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.

instrumentation/README.persistent_mode.md documents in the section about
deferred forkserver initialization:

This strongly implies that you can compile a program that uses __AFL_INIT()
under an `#ifdef __AFL_HAVE_MANUAL_CONTROL` guard with afl-gcc/-clang.
However, this currently fails:
$ cat example.c
#include <stdio.h>
int main(void) {
#ifdef __AFL_HAVE_MANUAL_CONTROL
__AFL_INIT();
#endif
puts("Hello");
}
$ afl-gcc example.c -o example
afl-cc++4.06a by Michal Zalewski, Laszlo Szekeres, Marc Heuse - mode: GCC-GCC
[!] WARNING: You are using outdated instrumentation, install LLVM and/or gcc-plugin and use afl-clang-fast/afl-clang-lto/afl-gcc-fast instead!
afl-as++4.06a by Michal Zalewski
[+] Instrumented 1 locations (64-bit, non-hardened mode, ratio 100%).
/usr/bin/ld: /tmp/ccuJHcpt.o: in function `main':
/home/jn/dev/fuzz/AFLplusplus/example.c:5: undefined reference to `__afl_manual_init'
collect2: error: ld returned 1 exit status
The issue here is an inconsistency in afl-gcc (i.e. afl-cc operating in GCC mode):
- afl-cc defines __AFL_HAVE_MANUAL_CONTROL and __AFL_INIT unconditionally
- __AFL_INIT relies on __afl_manual_init, which is defined in afl-compiler-rt.o
- afl-cc doesn't link afl-compiler-rt in GCC or CLANG mode
Since afl-gcc/-clang is documented as not supporting deferred forkserver
initialization, this patch omits the definitions of __AFL_HAVE_MANUAL_CONTROL
and related macros in GCC/CLANG mode.
This restores the ability to compile a deferred-forkserver program under
afl-gcc, if it can also be compiled under gcc.
[ In case someone reads this an feels adventurous enough (as I did) to
think about enabling deferred forkserver under afl-gcc: Whether the
deferred forkserver actually works can be verified by placing a
usleep(100000) or similar at the start of main (before __AFL_INIT()),
and watching the execution speed. It doesn't work. ]

__AFL_INIT() etc.
With the right -W options, compilers may complain about the cast of
string literals (for PERSIST_SIG and DEFER_SIG) to (char*), and they're
right to do so, because string literals are constant. Since some
projects enable -Werror, this can lead to a broken build with afl-cc.
Let's simply cast to (const char *), which preserves the constness of
the string literal.
