BIP440: Varops Budget for Script Runtime Constraint, BIP441: Restoration of disabled Script (tapleaf 0xc2) (#2118)

Browse Source 
* Varops: Two BIPs for Script Restoration: varops calculations and tapleaf version (0xc2).

Special thanks to Murch for teaching me mediawiki, and so much great
formatting and clarity advice.

* script restoration: fix MUL cost to account to round up B to word boundary.
Julian points out that the implementation does this, which improves accuracy
for the case of small B (since the term is multiplied: for normal OP_ADD etc
we don't bother, since the difference is very bounded).

* BIP 440, 441: official numbers, into README.mediawiki and renamed.
