65ac085a97 Add backwards compatibility handling with sysklogd v1.6 
This patch adds compatibility with sysklgd v1.6 and also adds the new
action flag "RFC3164" to explicitly be able to set old format.  This
format is the default, except for remote syslog.  Also, the rotation
support added in v1.6 has chnaged syntax which this patch addresses.

- Remote syslog defaults to BSD format, w/o timestamp and hostname
- Support reading log rotation without ';rotate=' prefix

58da3b6bd2 Mark strlcat() and strlcpy() as weak functions, for libsyslog 
The strlcat() and strlcpy() functions are only intended to be used
by syslog.c internally (and syslogd), when building libsyslog.

A user linking with libsyslog may have another library that provides
strlcat() or strlcpy() replacements.  We must therefore mark ours as
weak functions so they can be overridden.

This patch also add a convenience library for libsyslog, to control
the build deps. for libsyslog.  This is where external dependencies
should be addded (explicitly) when syslog.c is updated from NetBSD.
If you add new deps you likely want to mark them too as weak refs.
