iwlagn: clean up of transport layer

Move a few declarations needed by the transport layer to iwl-shared.h
Move iwl_cmd_meta, iwl_tx_queue and friends to the internal transport
header file.
Move iwl_device_cmd iwl_host_cmd and friends to iwl-trans.h since
these structs are used in the API to the transport layer.
Move get_cmd_string to the upper layer with a declaration in
iwl-shared.h.

- * Generic queue structure
- *
- * Contains common data for Rx and Tx queues.
- *
- * Note the difference between n_bd and n_window: the hardware
- * always assumes 256 descriptors, so n_bd is always 256 (unless
- * there might be HW changes in the future). For the normal TX
- * queues, n_window, which is the size of the software queue data
- * is also 256; however, for the command queue, n_window is only
- * 32 since we don't need so many commands pending. Since the HW
- * still uses 256 BDs for DMA though, n_bd stays 256. As a result,
- * the software buffers (in the variables @meta, @txb in struct
- * iwl_tx_queue) only have 32 entries, while the HW buffers (@tfds
- * in the same struct) have 256.
- * This means that we end up with the following:
- *  HW entries: | 0 | ... | N * 32 | ... | N * 32 + 31 | ... | 255 |
- *  SW entries:           | 0      | ... | 31          |
- * where N is a number between 0 and 7. This means that the SW
- * data is a window overlayed over the HW queue.
