773e69ea2e syslogd: Ignore temporary network problems when sending remote 
When sending to a remote syslog server, configured as an IP address or
when the DNS name has already been resolved, we may get temporary error
messages like ENETUNREACH and similar from sendmsg().

Before this patch the whole filed was placed in F_FORW_SUSP, like failed
DNS resolve, which introduces a 180 sec delay before even trying again.
A better approach is to just try again with the next syslog message.

84d70e63fc Drop libcompat to simplify build deps and really fix #11 
The original idea with libcompat was to keep as few objects as
possible for linking with libsyslog.  That in turn to prevent
a user of libsyslog from suddenly also getting strong binding
to symbols like strlcpy() from libsyslog, rather than their C
library of choice.

However, this caused strlcpy.c to be built as both .o and .lo
files, which in turn caused really bizarre build problems due
to bad DAG dependency.

This patch drops libcompat and instead marks all replacement APIs
as weak symbols, which a C library can override.
