Fix for ungetc() issues flagged by ext/Encode/t/perlio.t on VMS.
ungetc() and buffer snooping may not mix. So use buffer snoop
hooks to avoid ungetc() where available.
unread() falls back to using :pending layer, and fill has
VMS specific code (which should not get used) or ungetc()
which should work.
