Adrian Chadd 2fe1131c7b Add a threadid to the ah_decode API.
This adds the current thread ID to each logged register and mark entry,
allowing for easier debugging of concurrent/overlapping NIC operations.

* Register tracing support.

* Setting hw.ath.hal.alq=1 enables tracing of all register reads and
* writes to the file /tmp/ath_hal.log. The file format is a simple
* fixed-size array of records. When done logging set hw.ath.hal.alq=0
* and then decode the file with the arcode program (that is part of the
* HAL). If you start+stop tracing the data will be appended to an
* existing file.
