This reverts commit e9d2f72382cab75832721d859c3e731da071435d.

* Revert "fix custom trim for increasing data"

This reverts commit 86a8ef168dda766d2f25f15c15c4d3ecf21d0667.

* 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.

* typo

* Exit on time (#904)

* 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.

* fix new path to custom-mutators

* ensure crashes/README.txt exists

* fix
