3b3cc5736a Add .type and .size pseudo-ops to system call macros so that dynamic binaries
will link.  They must be used for weak symbols as well as strong ones.

946708bbea Remove a sentence from the BUGS section that claims non page-aligned
offsets don't work. It should really be documented that the returned
pointer can be in the middle of a fully-valid page when the offset
is not page-aligned, but I couldn't come up with suitable wording.

5acb7446b0 o Reflect repo-copy of extattr.[c3] from libutil to libc, moving
extattr namespace routines to the libc/posix1e directory.  While
  the extattr calls are not strictly POSIX.1e, POSIX.1e wasn't
  strictly ever approved, so I think that's OK.

- Renumber labels since the previous revision removed one.
- Remove useless and wrong comment.
  - Repeating the function name is just redundant.
  - The previous revision made the comment about %edx useless.
  - The comment about %eax was wrong (but did explain why %eax used to be
    fixed up).

7bfd54ac0f The kernel already fixes up %eax for parents that return from fork, so
don't bother manually fixing up %eax for the parent process by testing
the value in %edx and zeroing and already zeroed %eax.

ac8e56a7f9 Fixed namespace pollution related to `err' in libc in the same way as for
`warn'.  Now a whole 2 members of the err() family don't cause pollution.

This fixes world breakage in awk for NOSHARED worlds. contrib/awk/msg.c
has had its own version of err() for a long time, but this somehow
didn't cause problems until the update to awk-3.1.0.

8e2f75b833 The algorithm that computes the tables used in the BM search algorithm sometimes
access an array beyond it's length. This only happens in the last iteration of
a loop, and the value fetched is not used then, so the bug is a relatively
innocent one. Fix this by not fetching any value on the last iteration of said
loop.

70982dca88 Don't ignore unknown characters. The previous code treated a line like:
hosts:!!!!!!!!@@@@@$%^&*()()*$(files{}{}|||++!)(dns

exactly the same as:

hosts: files dns

Recover from parse errors by looking for the end of a line; this
allows entries without errors to still be parsed even if there is
an erroneous entry earlier in the file.

237c4e3a9e Add routines to convert time_t to/from fixed-bit fields. These routines
serve two purposes: (1) so we can maintain backwards compatibility with
protocols (rwhod, dump, etc...) that either assume time_t is 32 bits or
assume sizeof(time_t) == sizeof(int), or make other similar assumptions.
(2) To tag such routines (by the presence of these calls) for future
cleanup/extension work.

The 32->64 routine, time32_to_time() (when time_t is 64 bits, that is),
is defined specifically to implement temporal locality to properly set the
msb bits of a 64 bit time_t quantity, using the 50 year rule.  The locality
code has not been implemented yet (and doesn't need to be for a while),
but that is the intent.   This will allow us to maintain backwards protocol
compatibility past 2038.

These routines are intended to be platform and time_t agnostic.

we need to.
