version.pl: don't add an extra .00 for subminor if we don't need it
When producing the mangled version number, don't add a subminor if
there isn't a patch level or release candidate number. Thus, 2.05p1
is 2.05.00.01, but 2.05 can just be 2.05.

disasm: extension byte support in the disassembler

Add extension bytecodes to support operands 4+
The bytecode format assumes max 4 operands pretty strictly, but we
already have one instruction with 5 operands, and it's likely to get
more. Support them via extension prefixes (similar to REX prefixes).
For bytecodes which use argument bytes we encode the number directly,
however.
