## Detailed Description

Pointer with length in bytes.

This has a pointer to an array and the number of bytes in array. If number of bytes==-1 then CoinConditionalNew deletes existing pointer and returns new pointer of correct size (and number bytes still -1). CoinConditionalDelete deletes existing pointer and NULLs it. So behavior is as normal (apart from New deleting pointer which will have no effect with good coding practices. If number of bytes >=0 then CoinConditionalNew just returns existing pointer if array big enough otherwise deletes existing pointer, allocates array with spare 1+64 bytes and updates number of bytes CoinConditionalDelete sets number of bytes = -size-2 and then array returns NULL
