a2ff3a93f6 libsyslog: drop extra leading space in message 
When logging to a file we want a space to separate proc[pid]: from the
message, but for regular logging local/remote we don't want to inject
an extra space.

daba6cce09 Fix #5&: failure to reset socket count on SIGHUP 
As reported on GitHub. When logging to a remote host, after a few
SIGHUP's we get the following log message:

     Only 16 IP addresses per socket supported.

When closing all currently open sockets, the socket count must be reset
to allow for opening new ones, otherwise we'll run out of "counts".
Yes, this should be refactored to use the FreeBSD model implementation.

Problem introduced in v2.4.0, commit 075815e.

bcc3c7c1fb Prevent logfile corruption by control codes 
Do not corrupt logfiles when kernel messages contain control codes,
notably \n. Instead, preserve the kernel's protective C-style hex
encoding. For example, \n embedded in a message by a kernel-level
facility is received as "\x0a". Kernel-level facilities cannot be
trusted to use only syslog-safe codes in kernel messages. See:
<https://kernel.org/doc/Documentation/ABI/testing/dev-kmsg>

9427734546 Prevent overread when scanning the message buffer 
This change avoids the possibility of advancing past the null
terminator, by always testing the value at the pointer before
advancing the pointer.

While repairing this, I reconciled the code sections that read the
priority, sequence, and timestamp, so that they handle the pointer in
exactly the same way. This makes the source easier to maintain.
