"constants aren't, safe_strcat isn't."

This patch tries to fix a bug in the lpq parsing code that causes a
crash in lprng and BSD parsers when there are long lines in the
output.  A too-short length parameter was passed to safe_strcat, which
provoked a signedness bug.

It also makes the lpq parser consistently use fstring routines, rather
than its own hand-crafted strlen/sizeof guff.  Some variables were
renamed to make this obvious.

Finally safe_strcat is changed so that it actually does handle the
situation where strlen(dest)>maxlen, rather than crying for help by
clobbering -1 bytes of memory.
