src/sbbs3/ftpsrvr.c
Log Message:
Create the pack*.now with fmutex() to prevent simultaneous QWK packs

Probably only a problem on Vertrauen, but some QWKnet nodes, for some unknown reason, like to FTP-connect multiple times concurrently and request to download a QWK packet. This creates a race condition where the QWK packet gets created/downloaded/deleted before the second FTP connection can successfully download the same file, thus logging an error "opening file " on the server (VERT). So if the pack*.now file already exists, reject the download request. "What are doing?" is what I really want to ask these nodes, but better just throw them an error response and quietly move on.

Log Message:
Remove 3 second delay before disconnecting when max clients reached

This seems to be misguided and would only increase the chances of a DoS-type attack on TCP session resources.

A second 3-second delay upon malloc failure is also removed.

Log Message:
Don't delete pack####.now upon FTP-logoff

When a user logins to the FTP server concurrently, this creates a
race condition with an/the other FTP session that may be creating/
downloading a QWK packet. On Vertrauen, this results in the
occasional error removing the file since it was removed unexpectedly:
!ERROR 2 (No such file or directory) in main.cpp line 2747 (event_thread) removing "/sbbs/data/pack1111.now" access=0

Modified Files:
src/sbbs3/ftpsrvr.c
Log Message:
Detect TLS startup errors correct/fully

We can't (apparently) only rely on the return value of start_tls(), we have to check the value of the crypt session too.
This fix the possibility of this happening:
Jun 7 18:07:26 sbbs synchronet: ftp 0058 TLS ERROR 'No permiss.to perform this operation' (-21) opening keyset
Jun 7 18:07:26 sbbs synchronet: ftp 0058 <192.168.1.25> initialized TLS successfully

Instead, we'll detect the failure and disable FTPS support, logging "failed to initialize TLS successfully".

Log Message:
Fix segfault reported with ftpalias.cfg support in some cases

ftpalias() can return true even when the directory is not set to a valid directory index (i.e. set to -1), so using as an array index would definitely segfault. Part of commit 8ad30b6c by Deuce 3 years ago.

I didn't test this as I'm not sure exactly the combination of ftpalias.cfg content and FTP command received that would trigger this, but it's most definitely a bug.

So should fix the segfault reported in issue #288.

Log Message:
Fix FTPS upload failure: !DATA ERROR 0 receiving on data socket

Don't treat CRYPT_ERROR_COMPLETE (-24) as a socket error during upload since it's an indication that the remote closed the connection and is the normal "end of file/transfer" indicator, not an error. 'rd' is already 0 in this case, so no need to set at all (since recv() returns 0 upon disconnect and that's what we're emulating here).

Fixes issue #309 reported by Jas Hud.

Actually, this assessment was wrong. fmutex_open() was memsetting the fmutex_t to zero.
