internal list of logfiles. So if writev(2) fails for potentially transient
errors like ENOSPC, syslogd requires a restart, even if the filesystem has
purged.
This change allows syslogd to ignore ENOSPC space errors, so that when the
filesystem is cleaned up, syslogd will automatically start logging again
without requiring the reset. This makes syslogd(8) a bit more reliable.

dramatically speeds up the process of logging large amounts of data, while
leaving the essential semantics (that data can be expected to be on disk
if we crash) unchanged.
In my tests, this speeds up the rc phase of booting by 18-20%. [1]

Syslogd should ensure that f_file is a valid file descriptor when
f_type is FILE, CONSOLE, TTY and for a PIPE where f_pid > 0. If the
descriptor is closed/invalid then the type should be set to UNUSED
or the pid should be set to 0.
To this end:
1) Don't close(f->f_file) if we can't send a message to a remote
host because the file descriptor used for remote logging is
stored in finet, not in f->f_file. f->f_file is probably
uninitialised, so I guess we usually end up closing fd 0.
2) Don't close PIPE file descriptors if they are invalid.
3) If the call to p_open fails, don't set the pid.
The OpenBSD patches in this area set f_file to -1 after the fd is
closed and then avoids calling close if f_file < 0. I haven't done
this, but it might be a good idea too.

if the line doesn't match ^<%d>, then treat it as a regular kernel
printf line. Previously if a kernel printf message started with "<"
it would be interpreted as a log message, often with LOG_EMERG
level. This was triggered by some printfs in sys/dev/aic7xxx/, and
can also happen with the partial lines that result if syslogd cannot
keep up with the rate of arrival of kernel messages.

1. Hostnames were not treated case insensitively in all cases.
2. The method for stripping hostnames when reading the syslog.conf
differed from that when finding the hostname of an incoming request.
This lead to a broken match check. In my case, it meant I had to
have '@scooter.smi.example.com.example.com' to have 'logger.example.com'
properly save messages from 'scooter.smi.sendmail.com'.
3. Add paranoia to cfline() such that it doesn't try to access memory
