MULTI-PLATFORM CHANGES (all OS)
===========================================================================

--- Bug fixes ---

binkd.c:
- Fixed null pointer dereference: added null check after strdup() on SSH_CONNECTION
- Fixed potential use-after-free: mypid declaration moved to shared scope (HAVE_FORK || AMIGA)
- Added config file validation: reject filenames that look like FTN addresses

readcfg.c:
- Fixed null pointer dereference: added null check after calloc() in print_node_info_1()
- Fixed use-after-free: checkcfg() error path restructured (unlock before log)
- Fixed config reload storm: mtime stability check + 5s minimum between reloads (prevents partial-file parse and bind() failures)

inbound.c:
- Fixed double PATH_SEPARATOR: strnzcat(PATH_SEPARATOR) now checks if path already ends with separator (5 locations)

server.c:
- Fixed use-after-free: config->rescan_delay saved to local variable before main loop, re-read from new config after checkcfg() reload
- Fixed ENOTSOCK/EOPNOTSUPP recovery: extended OS/2-only ENOTSOCK handler to also cover EOPNOTSUPP

ftnq.c:
- Fixed try file deletion: only delete if file exists (prevents error on missing .try files)
