Log Message:
Debug the "thread_back field missing" error

Some QWKnet vote messages are failing:
evnt unpackREP <ENSEMBLE> !ERROR 2 (No such file or directory) in qwk.cpp line 1146 (qwk_vote) writing "/sbbs/data/subs/dove-gen" access=-105 info=smb_addvote thread_back field missing

Catch this problem a little higher up (in votemsg()) and log the message's reply-IDs to help determine what's the root-cause here. Don't bother calling smb_addvote() if thread_back is 0.

Modified Files:
src/sbbs3/postmsg.cpp
Log Message:
Bounds-check subnum in savemsg()

It's possible to use savemsg() (from JS MsgBase.save_msg()) to add a message
to a message base that's not a sub-board (not configured in SCFG->Message
Areas and not the "mail" base), but in that case, savemsg() would dereference an invalid sub in the scfg->sub array and crash. So use is_valid_subum()
to insure the subnum is a valid sub before using as an index.
