Subject: [PATCH] Created semfile_signal() to be optionally used in place of
ftouch() for signalling semaphore files. If not text specified, writes the
local hostname to file (for debugging purposes). semfile_list_init() handles
a gethostname() failure better. semfile_check() will initialize the passed
timestamp to the current time, if 0.
