Also reversed the order of newsgroup name and area-tag options for a sub-board.

Updated help text too to specify that sub's area-tag can be derived from newsgroup name, if one is specified.

So this started with addressing CID 174264: Big parameter passed by value (PASS_BY_VALUE), but then I fell down the constification rabbit hole. :-)

Addresses CID 350312

Addresses CID 350316

Addresses CID 350318 

But good practice anyway

with lseek() argument types, ftell() return type, etc.

Likely none of these would be actual issues with files < 2GiB in size.

resolved CID 350321

Before the "new filebase" merge of 2021, a user's batch download queue would be cleared when a QWK packet was successfully packed for them via the event thread (i.e. triggered via semaphore file). That was lost in the new filebase change (the batch download queue would not be cleared) - caught by Coverity (CID 350336).

It appears pre-packed QWK packets never cleared the batch download queue (does anyone actually use this feature in this day and age?) - fixed.
