Changes made for FT3 of UCX Majordomo V1.93:
1) Cent sign hack
   Date into CMS:       10-Nov-1996
   Engineer:            Karol Zielonko

Change '¢' to '"'. This allows the -C option in the listname-DIGEST forwarding
entry to be passed via the PIPE% mechanism to the VMS Majordomo digest script
with its case intact.

2) Minor diagnostics procedural change
   Date into CMS:       12-Dec-1996
   Engineer:            Karol Zielonko

If UCX$PIPE_MAILSHR_DEBUG logical is >= 20 then it won't delete the .TMP files
it creates. This is similar to behavior of UCX$MAJORDOMO_DEBUG logical.

Changes made for FT6 of UCX Majordomo V1.93:

3) Security/Privilege changes
   Date into CMS:       
   Engineer:            Karol Zielonko

Use new SYS$SYSTEM:PIPE_MAILSHR_REGISTRY.DAT to see if a particular username can
pipe to a particular .COM file in a username.

Require user that we are piping *from* to have the proper privileges (actually
it's just CMKRNL) explicitly turned on. CMKRNL is required when the pipe to
username is not the same as the pipe from username. The old code did require
CMKRNL so if a user with no privs tried to run the PIPE code directly (ie. send
to PIPE%"file someotherusername") they'd get an error. However with the old code
if the piping user had CMKRNL priv but didn't have it turned on the PIPE_MAILSHR
code would turn it on automatically, and then not turn it off. The new code
simply expects that the caller has the right privileges *and* that they are
turned on.

If the username we are piping to is the same as the one we are piping from then
no CMKRNL priv is required. This allows unprivileged users to send to PIPE%
directly as long as they aren't piping to another username. (Note that in order
to do this the protection on the PIPE_MAILSHR_REGISTRY.DAT file must allow world
read.)

If the username is left out of the PIPE% "address" string then we now default it
to the username of the process we are piping from.(The old default was to the
UCX$MAJORDOM account.)
