* While I'm there also replace ed(1) with red(1) because we do
not need the unrestricted functionality.

patch(1): Sync with FreeBSD

FreeBSD has taken our patch(1) completely (29 JAN 2013), forked it, and
has improved on it. It's a relatively simple sync. Selected change log:

More user friendly:
- Ask only once for "apply anyway"
- Tell user which patch failed rather than only # of hunk failures

Handle lines with null character:
- read buffer for pgets properly populated
- callers of pgets still misprocess buffer contents, but at least
pgets is more accurate

Make "patch < fubar" and "patch -i fubar" equivalent:
- previous behavior was source of "unexpected end of file in patch"
errors when null characters came from stdin

Fixed error handling where final fclose got skipped
Fixed target selection logic to match was was documented on man page
Synced with OpenBSD base

Introduce a new variable to hold the size of buf.

Improve portability of patch(1):
- basename(3) and dirname(3) can either return a pointer to
static storage (like on all BSDs) or modify the argument
(like on Linux). strdup the argument to suppo

Instead of i_ptr[++iline][0] = '\0', I've used a special empty char array
instead. I'm not sure if i_ptr[++iline] points to a valid memory location
under all circumstances and this is a safer bet.
