pid/eid before releasing from the reloads/reserve table, since an
admin initiated reload might be pending when a user does his own
load. Don't want to clear the reload state, or even worse, the
reserved state. There is a cross dependency created bewteen tmcd.c
and sched_reload on the pid/eid testbed/reloading. No biggie. I put in
a warning in both places.

postparse now uses tbcmds
sim.tcl is updated to close (and flush) the tbcmds output stream if it
exists.
tb_compat.tcl is the TB version that should be included by newstyle ns scripts.
tb_compat_nop.tcl is the NS version that should be renamed to tb_compat.tcl

  The DB is created with /users/stoller/cslogins.pl like this:

    ypcat passwd | awk -F : '{print $1}' | cslogins.pl cslogins

  This creates cslogins.db, which I then copied to /usr/testbed/etc.

  As soon as I get a clear idea of whether ypcat is going to work
  in the future, I will automate this part.
* Also added some sanity checking to make sure the email address looks
  reasonable (since I needed the domain anyway).
