Remove support for version-0 calling conventions.
The V0 convention is failure prone because we've so far assumed that a
function is V0 if PG_FUNCTION_INFO_V1 is missing, leading to crashes
if a function was coded against the V1 interface. V0 doesn't allow
proper NULL, SRF and toast handling. V0 doesn't offer features that
V1 doesn't.
Thus remove V0 support and obsolete fmgr README contents relating to
it.
