Subject: Apply patch from Georg Magschok to fix syslog behavior so that the
 '>' charactor can be logged, per rfc3164.

Also, a small patch from me to fix it so we use MAXLINE when allocating the
buffer, which is consistant with use everywhere else.  This is needed since
uClibc defines BUFSIZE as 255, causing lines to be truncated at 255...
