* 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.

* Fix memory errors when trim causes testcase growth
Modify trim_case_custom to avoid writing into in_buf because
some custom mutators can cause the testcase to grow rather than
shrink.
Instead of modifying in_buf directly, we write the update out
to the disk when trimming is complete, and then the caller is
responsible for refreshing the in-memory buffer from the file.
This is still a bit sketchy because it does need to modify q->len in
order to notify the upper layers that something changed, and it could
end up telling upper layer code that the q->len is *bigger* than
the buffer (q->testcase_buf) that contains it, which is asking
for trouble down the line somewhere...
* Fix an unlikely situation
Put back some `unlikely()` calls that were in
the e9d2f72382cab75832721d859c3e731da071435d commit that was
reverted.

When we started using AFL, it did not have an integrated GCC plugin.
There was one proposed by Austin Seipp, but for various reasons we
ended up using some of its infrastructure (runtime and wrapper), but
writing the GCC plugin proper from scratch.
With AFL++'s renewed interest in a GCC plugin, we rebased ours, with
some features that are or were missing in the one that was integrated:
* efficient, fully-functional inline and out-of-line instrumentation
Inline instrumentation was work in progress in the original plugin.
Controlled by AFL_GCC_OUT_OF_LINE.
* reproducible instrumentation
Obey -frandom-seed for pseudorandom number generation.
* licensing clarity and strict compliance
GPLv3+ for the plugin, that uses GCC internals; add a copy of the
license, as required.
* allow/deny list support
Copied and adjusted from the LLVM plugin implementation.
* neverZero support
Not as compact as the asm-wrapper version, but likely more efficient.
Both are quite thread-unsafe, with different caveats.
Controlled with AFL_GCC_SKIP_NEVERZERO.
