Patch 24 slightly speeds up ECPGsetcommit() at runtime, shifting
the strcmp() cost to the ecpg preprocessor. It also avoids the
confusion coming from a manually crafted C source that sends
a string different from "on" and "off".

Patch 25 is another subfeature of the ECPG readahead code.
ECPGopen() gets the user-specified (or unspecified) scrollable flag.
ECPGfetch() gets the amount of tuples to fetch separately as
a fixed value, which may or may not be also present in the variable
argument list. It makes it unnecessary to parse the FETCH/MOVE
query and extract the amount of tuples that way.
