Forcing the alignment prevents gcc from generating byte reads for word
member variables. Lack of this caused issues when the app processor
modified struct members and the modem saw a partial word write.

Some smd clients may write from multiple threads, in which case it's
not safe to call smd_write without holding a lock.  smd_write_atomic()
provides the same functionality as smd_write() but obtains the smd
lock first.

Don't mark a channel as allocated if we failed to allocate it
(perhaps the modem updated one table but not the other, etc)

This code provides the low level interface to the "shared memory
state machine" (smsm), and the virtual serial channels (smd), used
to communicate with the baseband processor.  Higher level transports
(rpc, ethernet, AT command channel, etc) ride on top of this.
