libc/stdlib: canonicalize_file_name() memory leak
Uclibc's canonicalize_file_name() is allocating temprary buffer of 4kB
(PATH_MAX), and passing it to realpath() as second argument. Function is
not checking if realpath() fails and memory is lost.

Fix syslog messages lost if syslogd is temporary busy
Commit 4139fe5aec935ba3f462dcaf6aafb6e5eadf1ab9 fixes SIGSTOPed syslogd issue.
but introduced new one - messages will be lost when socket buffer gets full,
not only if syslogd is stalled, but even if it accepts message slower than
someone sends and possibly leads to security hole, when important messages get
lost as result of attacker flooding.
Patch adds 1 second waiting for socket buffer can accept the message, helps
when syslogd is working hard. If it's stalled/SIGSTOPed, message will be sent
to errout as before. After that, further non-blocking /dev/log connect attempts
will fail immediately with EAGAIN error until syslogd reads some from it.

Fix syslog messages lost after syslogd restarts
If syslogd is stopped and restarted while a process has the log open, the next
message that process produces will be logged to the console and not to the new
instance of syslogd. Further messages will be routed correctly, but not the
first one.
