Remove more legacy libast code (re: f9c127e3, 651bbd56)

Browse source 
This removes #ifdefs checking for the existence of
SH_PLUGIN_VERSION (version check for dynamically loaded builtins)
and the SFIO identifiers SF_BUFCONST, SF_CLOSING, SF_APPENDWR,
SF_ATEXIT, all of which are defined by the bundled libast.
