free app inspect engines for a signature
For lists that are registered multiple times, like http_header and http_cookie, making the engines owner of the lists is complicated. Multiple engines in a sig may be pointing to the same list. To address this the 'free' code needs to be extra careful about not double freeing, so it takes an approach to first fill an array of the to-free pointers before freeing them.

Check content byte array compatibility with transforms.
The "content" array is presented to the transforms so that each transform may validate that it's compatible with the transform.
When a transform indicates the byte array is incompatible, none of the subsequent transforms, if any, are invoked. This means the first validation failure terminates the loop.
