dd88460800 We no longer need to include headers we don't use for sudo*.h files. 
Previously we needed to include headers required by the various
sudo*h files.  Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.

0460008c5b Handle EAGAIN like we do ENOMEM from poll() and select(). 
On some systems, poll() and select() can return EAGAIN instead
of ENOMEM if there is a kernel resource shortage.  In this case
we just re-enter the event loop and retry.

2b1e986572 Do not call poll(2) or ppoll(2) with nfds > RLIMIT_NOFILE. 
Both poll(2) and ppoll(2) will return EINVAL if the nfds function
argument is larger than the max files per process resource limit.
Prevent this by limiting the max number entries in the pfds[] array
to the RLIMIT_NOFILE soft limit.

04d1f56d90 Use struct timespec, not struct timeval in the event subsystem. 
Use ppoll() or pselect() if avaialble which use timespec.

866cfc4fc3 Add support for multiple Debug lines per program. Callers may 
register arbitrary debug facilities or use built-in defaults.  We
now use separate Debug statements for plugins and programs.
