is now ignored for special files, so that mounting root with option
noatime doesn't break reporting of idle times in programs like `w'.
The problem of execessive disk updates just to stamp atimes will be
handled for special files by only writing atimes to disk when inodes
become active. This works well because special files are relatively
uncommon and their atimes are even more disposable at panic time than
regular files' atimes.
1. mark atimes and mtimes of special files and fifos for update upon
successful completion of non-null i/o, not at the beginning of the
syscall.
2. never update file times for readonly filesystems. They were updated
for stats and closes but not for syncs. The updates were of course
only in-core and were thrown away when the inode was uncached, so
the times sometimes appeared to go backwards.
Improved comments in code related to (1) (mostly by removing them).
Unmacroized ITIMES(). The test in (2) bloated it even more. Don't
call getmicrotime() in the function version of it when we only need
the time in seconds.

This fixes a latency problem pointed out by: Bruce Evans <bde@zeta.org.au>
is allocated or not, rather than keeping a count and attempting to
know it it is in-use. POSIX says that once a key is deleted, using the
key again results in undefined behaviour.
The slices "struct" isn't really a struct; we allocate only part of
it in the fully dangerously dedicated case. Since the "struct" is
malloced, the page beyond it may not be mapped, so attempts to copy
it would crash. This problem became larger when the full struct was
bloated from < 1K to > 3K by the addition of (mostly unused) DEVFS
tokens some time before 2.2.0 was released.
(in particular, if DESTDIR is empty or "/"), then the host's ldconfig will
be the target's ldconfig by the time it is run.
Fixed disordering of env.
Don't know too much about libcrypt. Use exactly the same definition of
_libcrypt as lib/Makefile.
Don't build strip twice.

of bootstrapping lex, and don't forget what we were doing and build
some lex obj dirs twice.
so that the new behaviour is now default.
Solves the "infinite loop in diversion" problem when more than one diversion

Man page changes follow.
The new code is in -stable as the NON default option.
printf() of "Out of mbuf clusters - adjust NMBCLUSTERS or increase
maxusers" so that the message is more informative and so that it will
appear in the kernel message buffer.
the alloc is not M_DONTWAIT, then panic with "Out of mbuf clusters".
Callers that specify M_WAIT can't deal with getting a NULL buffer, so this
is a more graceful failure than randomly page faulting in the socket code
or elsewhere.
hard coded into too many things), it's not nice to go and change /home/src

the releases), but won't touch them once they are changed.
to be created if it's missing, otherwise completely ignore it's modes and
owners. Primary intended targets: /usr/src and /usr/obj.
Adjust the 'not created: File exists' message to mention that it's a
directory that's the problem, otherwise it doesn't make sense.
I had created chown-style -L and -P flag to control logical/physical mode
(ie: whether symlinks were followed), but the nochange flag is enough to
get the blasted thing out of my hair so I took them back out.
