User defined kill signal value (#678) 
* Adding AFL_KILL_SIGNAL environment variable

Controlling the kill signal used to end forked processes.

* Checking validity of AFL_KILL_SIGNAL env variable

This commit also sets a valid value in the environment to avoid
duplicating code in at_exit(). Changing data type of
fsrv->kill_signal to u8 to match last_kill_signal.

* Adding afl_kill_signal to AFL (environment) state

This commit simply introduces a struct member for future use. The
env variable is not used from the afl struct but from fsrv, where
its validity is checked, resulting in a FATAL in case of errors.

Option for specifying forkserver initialization timeout via environment variable (#522) 
* Addition of AFL_FORKSRV_INIT_TMOUT env var

This commit introduces a new environment variable which allows to
specify the timespan AFL should wait for initial contact with the
forkserver.

This is useful for fuzz-targets requiring a rather long setup time
before the actual fuzzing can be started (e.g., unicorn).

* add .swp files to .gitignore

* Inherit init_tmout in afl_fsrv_init_dup

Without this patch, the forkserver would spawn with a timeout of 0 in
cmplog mode, leading to an immediate crash.

Additionally, this commit removes a spurious whitespace.

* Initialize afl->fsrv.init_tmout in afl_fsrv_init

Not all afl-components will need the new AFL_FORKSRV_INIT_TMOUT
environment variable. Hence, it's initialized to the safe "default"
value from before in afl_fsrv_init now.
