* Add --null option (sort #defines here)
* Add process_lines function to util.c that reads newline-terminated
or null-terminated lines (with self-sizing buffers, etc) and iteratively
invokes a provided function. Use this to dramatically simplify:
-T handling for -c, --exclude-from-file, and --include-from-file.
* Add -T handling to -x (via include_from_file)
Hopefully, this will fix the openoffice port and a couple of
others that rely on -T and --null.

read_extract_dir (which creates directories in the archive). This
brings a number of advantages:
* FINALLY fix the problems creating dirs ending in "/." <sigh>
* Missing parent dirs now get created securely, just like explicit dirs.
(Created 0700 initially, then edited to 0755 at end of extraction.)
* Eliminate some duplicate code and some weird special cases.
While I'm cleaning, inline the regular-file creation code as well.
This change also pointed out one API deficiency: the
archive_read_data_into_XXX functions were originally defined to return
the total bytes read. This is, of course, ambiguous when dealing with
non-contiguous files. Change it to just return a status value.
Instead, display a warning, clean up, and let main() return the error.
In particular, this means that chdir() problems won't leave broken
archives, though they will prompt an error exit value.
to warn about attempts to sleep in the I/O path. This change pushes the
definition and use of 'mymutex' behind #ifdef WITNESS to avoid the cost
in non-debugging cases. This results in a clear .22% performance win for
512 byte and 1k I/O tests on my SMP test box. Not much, but every bit
counts.
This requires some non-trivial surgery to the options parsing.
While here, let people who only have getopt() access long options
through the -W longopt=value convention.
associated with performing a wakeup on the socket buffer:
- When performing an sbappend*() followed by a so[rw]wakeup(), explicitly
acquire the socket buffer lock and use the _locked() variants of both
calls. Note that the _locked() sowakeup() versions unlock the mutex on
return. This is done in uipc_send(), divert_packet(), mroute
socket_send(), raw_append(), tcp_reass(), tcp_input(), and udp_append().
- When the socket buffer lock is dropped before a sowakeup(), remove the
explicit unlock and use the _locked() sowakeup() variant. This is done
in soisdisconnecting(), soisdisconnected() when setting the can't send/
receive flags and dropping data, and in uipc_rcvd() which adjusting
back-pressure on the sockets.
For UNIX domain sockets running mpsafe with a contention-intensive SMP
mysql benchmark, this results in a 1.6% query rate improvement due to
reduce mutex costs.
The overhead of unconditionally allocating TIDs (and likewise,
unconditionally deallocating them), is amortized across multiple
thread creations by the way UMA makes it possible to have type-stable
storage.
Previously the cost was kept down by having threads created as part
of a fork operation use the process' PID as the TID. While this had
some nice properties, it also introduced complexity in the way TIDs
were allocated. Most importantly, by using the type-stable storage
that UMA gives us this was also unnecessary.
This change affects how core dumps are created and in particular how
the PRSTATUS notes are dumped. Since we don't have a thread with a
TID equalling the PID, we now need a different way to preserve the
old and previous behavior. We do this by having the given thread (i.e.
the thread passed to the core dump code in td) dump it's state first
and fill in pr_pid with the actual PID. All other threads will have
pr_pid contain their TIDs. The upshot of all this is that the debugger
will now likely select the right LWP (=TID) as the initial thread.

Yes, some devices return incorrect lengths in their string
descriptors. Rather than losing, do what Windows does: just
request the maximum size, and allow a shorter response. Obsoletes
the need for UQ_NO_STRINGS, and therefore these "quirks" are removed.

In the "seemed like a good idea until I found the fatal flaw"
department... Attempting to read a maximum-size string descriptor
causes my kue device to go completely apeshit. So, go back to the
original method, but allow the device to return a shorter string than
it claimed.

Most notably, this cleans up messages when shutting down from
single user. In such a case there are usually no daemons running,
but their pid files are still in /var/run. This causes rc.d to
output diagnostics about daemons with pidfiles, but that are
not running.

No current line disciplines have a dynamically changing hotchar, and
expecting to receive anything sensible during a change in ldisc is
insane so no locking of the hotchar field is necessary.

Failure to properly mask off UE_DIR_IN from the endpoint address
was causing OHCI_ED_FORMAT_ISO and EHCI_QH_HRECL to get set
spuriously, causing rather interesting lossage.
Suddenly I get MUCH better performance with ehci...

we have to revert to TTYDISC which we know will successfully open
rather than try the previous ldisc which might also fail to open.
Do not let ldisc implementations muck about with ->t_line, and remove
code which checks for reopens, it should never happen.
Move ldisc->l_hotchar to tty->t_hotchar and have ldisc implementation
initialize it in their open routines. Reset to zero when we enter
TTYDISC. ("no" should really be -1 since zero could be a valid
hotchar for certain old european mainframe protocols.)
Now that the devs files are marked before-depend, we can remvoe them
from a few places they were explicitly mentioned (along with
BEFORE_DEPEND).

Reduce the need for hard coded *devs in various makefiles by declaring
them before-depend.
Other bugs in the handling of *devs remain, but this is the start of
the cleanup. These will be address in future commits.
