genfile commands would not terminate properly or
would end up de-synced with the host in one way or
another.
to fix this, i updated the GEN_FILE data type and
sub-protocol to now define the commands as download
or upload on the NEW_CMD frame so clients can now
define the direction of the GEN_FILE data of the
various GEN_FILE commands at the very start instead
of trying to determine that at run time.
also fixed this by creating the onTerminate() virtual
function in CmdObject and have it call this function
when term() is called. this makes it possible to
properly put the command object in a reset state if
using parameters outside of the base class when
term() is called.
updated all documentation related to the GEN_FILE
sub-protocol to reflect these changes.
fixed ASYNC_DEBUG_TEXT to self correct the ipc type
to PRIV_IPC so no debug messages can accidentally be
sent to peers.
fixed some errors found in the documentation and fully updated the internal
commands docs as well.
also updated the internal module to now respond to KILL_CMD so it can now be
signaled to terminate gracefully.
-the add_mod command now requires the -mod_path argument as it should.
-the session now filter out bad NEW_CMD frames based on bad command names and incorrect
frame sizes.
-modules running in list mode can now send ERR frames to the session to log error
messages to the host database.
