sh: Remove output.c's reset() handler.

These cleanup operations are not needed because they are already performed
after an optimized command substitution (whether there was an error or not).
sh: Remove mkinit.

Replace the RESET blocks with regular functions and a reset() function that
calls them all.

This code generation tool is unusual and does not appear to provide much
benefit. I do not think isolating the knowledge about which modules need to
be reset is worth an almost 500-line build tool and wider scope for
variables used by the reset functions.

Also, relying on reset functions is often wrong: the cleanup should be done
in exception handlers so that no stale state remains after 'command eval'
and the like.
ext2fs: Don't assume that on-disk format of a directory is the same
as in <sys/dirent.h>

ext2_readdir() has always been very fs specific and different
with respect to its ufs_ counterpart. Recent changes from UFS
have made it possible to share more closely the implementation.

MFUFS r252438:
Always start parsing at DIRBLKSIZ aligned offset, skip first entries if
uio_offset is not DIRBLKSIZ aligned. Return EINVAL if buffer is too
small for single entry.

Preallocate buffer for cookies.

Skip entries with zero inode number.

Avoid trashing IP fragments:
- Only enable UDP/TCP hardware checksums if CSUM_UDP or CSUM_TCP is set.
- Only enable IP hardware checksums if CSUM_IP is set.

Set the device description after we call uart_probe(). In uart_probe()
we call device-specific probe functions, which can (and typically will)
set the device description based on low-level device probe information.
In the end we never actually used the device description that we so
carefully maintained in the PCI match table. By setting the device
description after we call uart_probe(), we'll print the more user-
friendly description by default.
Fix typo.

Enhance the description of NOTE_TRACK:
- NOTE_TRACK has never triggered a NOTE_TRACK event from the parent pid.
  If NOTE_FORK is set, the listener will get a NOTE_FORK event from
  the parent pid, but not a separate NOTE_TRACK event.
- Explicitly note that the event added to monitor the child process
  preserves the fflags from the original event.
- Move the description of NOTE_TRACKERR under NOTE_TRACK as it is not a
  bit for the user to set (which is what this list pupports to be).
  Also, explicitly note that if an error occurs, the NOTE_CHILD event
  will not be generated.
