    _______________________________________________________

Details:

We're deprecating 'nreqs' in 2.6 (patch #4662) and abolishing them in 3.0
(patch #5652).

This means that some rulesets representable in 2.5 will no longer be possible
in later versions, because each of reqs and nreqs allowed MAX_NUM_REQS==10
clauses, whereas now the combined list with present=TRUE/FALSE must be 10
clauses or less.

Bump MAX_NUM_REQS to 20 on 2.6 and later.

For what it's worth, a requirement takes up 8 octets on the wire, so this
bumps some max packet sizes by 80 octets.

(I nearly bumped into this limitation with my fixes for bug #23610 / bug
#23609, but managed to keep the relevant effect to 10 clauses.)
