Accessing an AID requires opening a channel to that application.
This patch implements session management API's so that other atoms
can access a given AID. Now any atom can get a session ID from the
sim atom. This will either reuse an existing session or open a new
channel. Once done, the atom should release the session which will
automatically close the channel when no atoms are using it.
The major functional change to the sim atom is the AID discovery
phase of initialization. Now, the sim atom is not 'ready' until AID
discovery finishes where before, the sim was 'ready' after the IMSI
had been obtained. If application discovery is not supported then
the the sim atom behaves as it did before.

Several file read API's were re-using the same code to append
a file path. This code was moved into a helper API.
