Initial code commit for fixing up sleds.

1. There are now two functions to identify
   the size of the dollop entry.
2. The plugin must identify whether or not
   it plopped the actual instruction as 
	 opposed to just bytes in the dollop entry's
	 opening and/or closing.

FallthroughPatched: This is whether or not the
fallthrough to the subsequent dollop has been
converted into a jump instruction that has
been added to the dollop. This affects future
size calculations.

Coalesced: This is whether or not this dollop
has been coalesced with its fallthrough dollop.
This affects size calculations.

Add support for tracking dollop entry membership in dollop and retrieving a dollop entry's fallthrough in a dollop.
