Log:
Add some code I wrote while bored on a train.  Basically, it introduces a
second container for iax2 pvt structures.  It puts active pvt structs in a hash
table as soon as the peer's call number is known, or when it changes due to a
transfer or something.  The hash is done on the peer's IP address, port number,
and their call number.  Then, the operation that is done to find the pvt struct
for each incoming media frame is *highly* optimized.  Instead of doing a linear
search through every possible call number, locking and unlocking each one, it
just calculates the hash, and finds it in the hash table.  Each hash bucket is
just a linked list, but the number of objects in each bucket will be
relatively small compared to what was done before.
