the mpmt MPM look almost exactly like the original prefork MPM.  Basically,
all that's left is re-naming the defined directives so they work with 1.3
config files.  That will come later.

   was not getting compiled into mpm_common.
this appears to keep mpmt_pthread running properly. dunno whether a similar
   issue exists for prefork or dexter. (until all are torched)

  Advisory: This patch is still anywhere but complete.  However, it
  resolves most of the big bugs of the services to mpm relocation.
  I apologize that it's taken this long to get back on this.

  Brought across; Keep console open (needs a bit of cleanup and could
  be done better now for 2.0), service error event logging, and some
  other minor threading cleanup.

  Big issues remain: logged errors (even APLOG_STARTUP) drop into the
  logfile in spite of our interest in getting them to the user's console.

  Some threading sequences may yet be out of sorts, and those will be
  cleaned up by the end of the week.

defined but ap_sendfile fails with APR_ENOTIMPL, the BUFF implementation
of ap_send_fd will get a shot at serving the request.  This fix is
required to get Apache working on 95/98 again and can also be useful on
Unix systems where sendfile is available via a servicepack/fixpack/PTF
on a particular level of the OS (e.g., AIX 4.3.2 base does not include
sendfile but is is available with a PTF).

This fix also reimplements the mod_file_cache sendfile_handler using
ap_send_fd and sets the connection aborted flag if the sendfile fails.

Future modification... Add code to ap_send_fd to hijack any data in the
client BUFF structure and send it along with the sendfile.

and removes the duplicated code from all effected MPMs.  The only this
doesn't touch, is Windows.  That MPM was using a different setup_listeners.
If one of the Windows guys would like to modify the WinNT MPM to use the
same setup_lsiteners, that would be VERY cool.

a bit and either mpmt or three separate MPMs are chosen.

the C file to determine if a module is present.  mpmt emulates three
different MPMs though.  If the default config file we have sane defaults
for each of the three MPMs that mpmt emulates.

To fix this, the build process creates a soft link to the original MPM name
during the configure process, and the build process actually compiles that
file, instead of the original mpmt.c.  This allow the mpmt MPM to work
just as well as mpmt_pthread.

said that I really wanted --with-mpm=mpmt_pthread. I made it listen :-)

the new behavior: if you explicitly state an MPM, then it is used. if it
guesses one, then it is free to replace that guess with mpmt.

[ yes, this will probably change again when mpmt works ]

and prefork.  This basically just combines a lot of common code.  This
builds and serves pages in all three modes, but I don't think killing
the server works in any of them.  The configuration system hasn't changed
at all, so using --with-mpm=(prefork|dexter|mpmt_pthread) all work.

My goal is to remove the three separate MPMs in a few days, and then work
on merging one of the BeOS and the OS/2 MPMs into this as well.  :-)
