Monster.

I wanted a couple of features for filters (e.g. blocked IP addreses):
- expiration date, optionally (only block for a limited time)
- display details of reason for filter in log messages (at time of block)

I've been thinking for some time that these files should be converted to .ini,
but then it occurred to me that I could do a sort of hybrid where the metadata
was key/value pairs tab-delimited from the search-pattern (first text on the
line). This is backward comaptible, relatively easy to view/edit by hand, and
extensible (easy to add/remove metadata fields in the future). So they'll
remain as text/*.can files.

The maximum line length for findstr/trashcan parsed files extended from 255 to
1000 characters.

Moved all trashcan-related functions from scfglib1.c to (new file) trash.c.

For the first time, I actually tested a build on WSL *before* committing to
Git. So, this *should* pass CI the first time. :-O

Also a bit more constification and cleared up the legacy sbbs_get_ini_fname()
usage: the hostname argument hadn't be used in a long, long time.

Don't return an error if the node#/node.cnf file can't be opened for all uses of load_cfg() except from the terminal server. This fixes #214 for Tracker1
