Previously, __lsan_do_leak_check() was run when using __AFL_LEAK_CHECK,
however this was the incorrect function to use. According to the
documentation: "Subsequent calls to this function will have no effect
and end-of-process leak check will not run".
This meant that if the memory did not leak on the first usage of
__AFL_LEAK_CHECK, subsquent calls to this macro would never do anything.
Likewise, it is not possible to use an LSAN suppression list with
symbolize=0, so instead __lsan_disable and __lsan_enable are used to
'ignore' certain memory allocations where needed.
* 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.
