c814e2e7e8 Remove template matching and pseudo opcodes 
The current code contains a rather complex script template matching engine,
which is only used for 3 particular script types (P2PK, P2PKH, multisig).
The first two of these are trivial to match for otherwise, and a specialized
matcher for multisig is both more compact and more efficient than a generic
one.

The goal is being more flexible, so that for example larger standard multisigs
inside SegWit outputs are more easy to implement.

As a side-effect, it also gets rid of the pseudo opcodes hack.

da894ab5da Accept any sequence of PUSHDATAs in OP_RETURN outputs 
Previously only one PUSHDATA was allowed, needlessly limiting
applications such as matching OP_RETURN contents with bloom filters that
operate on a per-PUSHDATA level. Now any combination that passes
IsPushOnly() is allowed, so long as the total size of the scriptPubKey
is less than 42 bytes. (unchanged modulo non-minimal PUSHDATA encodings)

Also, this fixes the odd bug where previously the PUSHDATA could be
replaced by any single opcode, even sigops consuming opcodes such as
CHECKMULTISIG. (20 sigops!)
