address @markj's comment about deallocate

I decided I will completly rework big parts of the code, I will reopen a review when ready, I don't want to waste your time, in the mean time, thank you all for the review so far.

Handle partial non-blocking read on the control socket
Add forgotten support for proper shutdown (oups)

Handle errors from setsid() and chdir("/"), just in case

Activate the reaper for all kind of legacy scripts
Fixes some tokenizer issue
xread now can take a timeout parameter
rcctl status now prints the nojail and nostart status
fix a bunch of tests
dangerous env vars concept removed
varity the PROC_REAP_STATUS
use waitid instead of waitpid
