fix some bugs with -C flag; one with queuing from Teus

back out attempt to use flock in the queue -- we don't in gerneral have
an open file descriptor available.

Try to use flock call (this doesn't work because we don't always have an
open fd); security and performance fixes from Kirk Smith at Purdue; "a"

change macro expansion character from $ to \001 so that $'s can be
used in headers -- the .cf file is unchanged by mapping $ to \001.
\001 is now a manifest constant.

4.2 release version

include fix

%d => %ld in mailq for PDP-11's

Minor formatting change so that the entire text of the message can
be printed.

Don't put Resent-*: lines in queue file to prevent outputing them
inappropriately in the sent message.

Don't artifically add a "from: $q" when running the queue -- this seems
to cause the from line in the qf file to be ignored.

implement classes and mailer flags as a bit map; define new class 'w'
as the set of all hosts we are known by

define a newline in "nullmailer" so that queue files get written with
newlines between the "H" lines.

release daemon resources when running the queue

be sure to open a new transcript on every queue run; when returning
an SMTP transcript, only send the last half (i.e., that part which
describes the sending half).

split up FULLSMTP flag -- now have "X" (M_XDOT, use hidden dot algorithm),

"p" (M_FROMPATH, use reverse-path in MAIL FROM:<> command), and "L"
(M_LIMITS, enforce SMTP line limits). I would like to change the format
of the mail defn one more time to make named fields so that it would
be more extensible.

fix botch that causes sendmail to core dump when there are large
numbers of requests

give more useful error messages (including the errno that caused
a temporary failure); reflect these messages out to mailq

print "request" instead of "requests" if there is only one request

process timeouts like normal errors, so that they will get delivered to
the correct address (i.e., the Errors-To: address)

fix botch in reading the queue that caused it to throw away the last
entry it read -- this was particulary obvious with only one entry in
the queue.

clean up output of mailq mode

Put CRLF on all lines in user SMTP. Pass this info down to
innumerable routines.
