Jon Griffiths 4b38696613 pull_length: Take structure size into account when checking max 
When a serialized length refers to an array of structures, the trivial
DOS prevention can be out by a factor of sizeof(serialized struct). Use
the size of the serialized structure as a multiplier to prevent this.

Transaction inputs are the motivating example, where the check is out by
a factor of ~40.

These are standard bitcoin manipulation routines which should be
provided by any normal bitcoin library in whatever language you choose.

The ones here are standalone ones taken from bitcoin core and some I
wrote, many taken from bitcoin-iterate and pasted in here.
