b1f92fa229 META MODE: Update dependencies with 'the-lot' and add missing directories.
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

547e0acbec patch: Bring in xstrdup and use it when appropriate.
The function savestr allows NULL return values during Plan A patching so in
case of out of memory conditions, Plan B can step in.  In many cases, NULL
value is not properly handled, so use xstrdup here (it's outside Plan A/B
patching, which means that even Plan B relies on successful operations).

c1a08643e3 patch: unsign the line length to avoid overflows.
Patch(1) uses a short int for the line length, which is usually
sufficient for regular diffs, but makes no effort to signal
when there is an overflow.

Change the line length to an unsigned short int to better use
the fact that a length is never negative.  The change is loosely
inspired on a related change in DragonFly, but we avoid spending
more memory than necessary.

While here adjust the messages to be clearer on what is happening.

calloc, and therefore wasted time initializing arrays that

reallocf().

21244d5227 Make the BSD-licensed patch the default.
The BSD-licensed patch(1) command has matured and it's behaviour
can be considered equivalent to the older version of GNU patch
in the tree.

The switch has been extensively tested [1] and only two ports
presented regressions, which have since been fixed.

For convenience a new WITH_GNU_PATCH option is available,
but it will likely be removed in the near future.

6d85e39be1 Merge r252513 from src/gnu/usr.bin/patch into src/usr.bin/patch:
Properly handle input lines containing NUL characters such that pgets()
accurately fills the read buffer.

Callers of pgets() still mis-process the buffer contents if the read line
contains NUL characters, but this at least makes pgets() accurate.

0571fd57a1 Merge r252512 from src/gnu/usr.bin/patch into src/usr.bin/patch:
Make it so that 'patch < FUBAR' and 'patch -i FUBAR' operate the same.

The former makes a copy of stdin, but was not accurately putting the
content of stdin into a temp file.  This lead to the undercounting
the number of lines in hunks containing NUL characters when reading
from stdin.  Thus resulting in "unexpected end of file in patch" errors.

2360cb0eea The error handling for writes to the target file could lead to the final
fclose() being skipped. Fix this by using boolean "&" and "|" instead of
short-cut operators "&&" and "||".
While here, increment the last part of the version string. The reason is
the fixed output file selection logic in pch.c, which was committed as
r250943, yesterday.

6b239879f8 Fix target selection logic, which did not comply with the man page.
Instead of using the file with the least order of path name components,
shortest filename and finally the shortest basename (with the search
stopping as soon as one of these conditions is true), the first filename
checked was used as the reference, and another filename was only selected
if all of the above comparisons are in favour of the latter file.

This was wrong, because filenames with path less components were only
considered, if both of the other conditions were true as well. In fact,
the first filename to be checked had good chances to be selected in the
end, since it only needed to be better with regard to any one of the
three criteria ...
