add way to lock portion of plugin buffer for TSR plugins

Browse source 
Some things in core that should probably be plugins steal the plugin buffer
for their own use, TSR plugins have no way to detect or prevent this
lock buffer reserves buffer_size bytes directly after the plugin itself
returns the unreserved bytes still available from the plugin buffer
