Return int value for "string not found" rather than crash/segfault. Seems the better option.

Addresses CID 319116 and 319090

This started with a Coverity issue (CID 33230) which got me looking at this function and wondering: why is str2 being NUL-terminated here? Why is the length of str2 to be calculated on successive lines? What is with this (long)((long)((long)((long)) typecast?

This was some of the oldest code in Synchronet (along with a lot of the other functions in this file). I tried to keep as much intact as possible while still improving the logic and readability.

Do nothing if online != ON_REMOTE. Eliminates some if(online == ON_REMOTE) clauses.

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.

If a callback deletes the one-shot event that invoked it, the
event pointer in the caller would be to free()d memory with
hilarious results.

Upon connecting, a client will be sent a list of who's online on
the local BBS as well as other systems (if you and they are set
up for instant messaging). Updates will be sent for subsequent
events (logon, update, logoff).

Mostly intended for use by local consumers; you probably don't
need to open any ports for this.

Nothing uses this at the moment and you do not need to add it
to your config. Eventually it'll bring interBBS presence and
messaging back to webv4 and probably introduce a fancier textmode
imsg module.

Properly throw an error instead.

Fixes issue #252.

Just don't check the python version at all.  If your python is older
than 2.5, you're already having other issues.

but round-up non-zero values to 1K.

Appended very important trailing linefeed.

It's a wrapper for filedat.c -> format_filename() which can truncate and pad a filename for display purposes.

Tweak the poll() implementation to match.

Should fix #248

The biggest difference is that you can combine all files from multiple dirs
into a single sorted list and you can sort on any property (field) value.

The byte/credit format is very customizeable, the output format is completely
customizeable.

By default, just the filenames are output, but either use '-ext' or one or
more '-v' values to add more fields. Use -p=list to specify a comma-separated
list of properties to print.

Instead, return the fractional size in KB's with 2 digits of precision.

Fixed up some of the variable names.

Prevents weird issues with getting remote address.

When only reading the index (detail = file_detail_index), smb_getfile() just sets the file->name convenience pointer to point to the name in the index. Then when loadfiles() would sort the list, these pointers would not be adjusted (so they would point to the wrong names) resulting in a corrupted file list (e.g. name/size mismatches and no logical sort order).

The solution is to call smb_getfile() on each file *after* the read index records have been sorted.

This also means that the sort-by-name routines needed to always sort using the index name and not the convenience pointer (which is NULL in this case).

While fixing this, I noticed there was no bounds checking in the loadfiles() and loadfilenames() read-loops, so if the indexes happened to be longer than the total_files value from the status header, a buffer under-alloc/overflow would occur and a likely crash as a result. So stop reading the index when the expected maximum number of index records have been read.

Returns a floating-point formatted size estimate more in-line with my
preference (e.g. 17.0G instead of 17,000M).

Can find duplicate files in your file bases by name and/or hash sum - fast!
Can output simple text or JSON format.
Run 'jsexec dupefind' to search just for duplicate files by hash (SHA-1)
or run 'jsexec dupefind -help' for the various usage options.

Adds from/tags/desc/extdesc properties, even when absent or blank.

When parsing a file object, set the from, desc, tags and cost properties only if they already have been set or the new values is non-blank/0.
