86b71bcd03 Cleanup hostname matching in syslogd:
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
   outside of the bounds of the f_host string.

4. While I am here, get rid of an outdated comment, argv[{0,1,2}] are now
   checked for NULL after the strdup() calls.

025fad7000 Introduce to the !program specification a capability similar to the one
that already exists for hosts: being able to specify a section that applies
to every program *except* the one in question.

The normal syntax for program specification is still valid. For the new
capability, one uses:

!-program

Since there is no way to specify a program beginning with a dash in the old
syntax, as it would be interpreted as the case above, the following
alternative syntax to the original capability is provided:

!+program

This shouldn't introduce incompatibilities with any syslogd configuration
in production because -stable's syslogd does not support a dash anywhere in
the program specification.

84553dbc63 Don't give up on a remote log host when we get a EHOSTUNREACH or
EHOSTDOWN. These are often transient errors (when the remote host
reboots, temporary network problems, etc.), and we'd rather err on the
side of caution and keep trying send messages that never arrive than
just give up.

Note that this is not an implementation of the "back-off" methods
given in the PR. Those just seem too complicated. Why not just keep
trying each time? Trying and failing doesn't really consume
significantly more resources than if we were successful for each
message.

e3143ba142 When reading a program name from the syslog configuration file,
do not stop copying it into a buffer when encountering a

66ace759e4 Make the default kernel prefix "kernel:" instead of the boot file,
with the old behavior available via the -o option (it might still be
useful if one has many kernels and cares which messages came from
which).  If the boot file is not used as the prefix, it is still
logged once at startup.

This change is prompted by the fact that the boot file is now much
longer ("/boot/kernel/kernel" vs. "/kernel"), which significanlty
bloats the syslogd output.

74bd16fb3b The previous commit appeared to just shove the bug under the carpet rather
than really solve it.  This approach (inspired by Ruslan's patch) solves
the real problem by stripping the local domain off the host name in the
config line structure.

Also mark a bunch of code sections that either do not check the return value
of a strdup(), malloc() or calloc() call, or do not properly handle a NULL
return.

9f1000c54f - Silence warnings: apply `const' generously, mark some variables
__unused, and change local variables named `sin' (struct
  sockaddr_in) to `sin4'.  (`sin' conflicts with the definition of
  sin(3), which gcc assumes to be defined even if math.h isn't
  included (it's a builtin).  This is probably a bug in gcc.)

- Apply WARNS=1.  WARNS=2 was not used because this program assigns
  string literals to (struct iovec).iov_base for writing, and the only
  clean way to silence -Wwrite-strings in that case would be to
  strdup() and consequently free() those literals, which I considered
  too disruptive.
