Move all the iwlXXX_abgn_cfg forward declaration to a separate file
so that iwl-pci.c doesn't need to include iwl-agn.h that includes
all iwl-dev.h
This allows to provide real encapsulation. Dereferencing iwl_priv
in the bus layer will now lead to a compilation error.

Remove iwl_transport_register which was a W/A. The bus layer knows what
transport to use. So now, the bus layer gives the upper layer a pointer to the
iwl_trans_ops struct that it wants to use. The upper layer then, allocates the
desired transport layer using iwl_trans_ops->alloc function.
As a result of this, priv->trans, no longer exists, priv holds a pointer to
iwl_shared, which holds a pointer to iwl_trans. This required to change all the
calls to the transport layer from upper layer. While we were at it, trans_X
inlines have been renamed to iwl_trans_X to avoid confusions, which of course
required to rename the functions inside the transport layer because of
conflicts in names. So the static API functions inside the transport layer
implementation have been renamed to iwl_trans_pcie_X.
Until now, the IRQ / Tasklet were initialized in iwl_transport_layer. This is
confusing since the registration doesn't mean to request IRQ, so I added a
handler for that.

It will hold declaration of functions and forward declaration of struct that
are used by several layers.
This will allow modules not to include iwl_priv. iwl_bus and iwl_trans are
still visible to all.
All the layers share the module parameters, move the struct to iwl-shared.h.
Also add all module parameters to iwl_mod_params instead of having them as
global static. This includes
* debug_level
* ant_coupling
* bt_ch_announce
* wanted_ucode_alternative

which is obviously wrong, the user should not see the *_UCODE_API_MAX

The problem are the
#define *_MODULE_FIRMWARE(api) *_FW_PRE #api ".ucode"

Fixed by using __stringify() from linux/stringify.h.

We use priv->mutex to avoid race conditions between iwl_chswitch_done()
and iwlagn_mac_channel_switch(), when marking channel switch in
progress. But iwl_chswitch_done() can be called in atomic context
from iwl_rx_csa() or with mutex already taken from iwlagn_commit_rxon().

To fix remove mutex from iwl_chswitch_done() and use atomic bitops for
marking channel switch pending.

2.4GHz only devices.

There's no need to keep both normal and BT statistics
versions around all the time in memory when we only
use a subset of both. So keep only the subsets that
we need in memory, depending on the debug config).
Also, in doing so, we can remove all the calls to
iwl_bt_statistics() in the driver as we'll just
access the copied statistics now.
Finally, also remove this call from the one place
where it might still be needed and automatically
detect what kind of statistics the device is sending
based on their size. This way, we don't need to keep
track of which devices do what any more, which is
good since this is subject to change based on the
ucode version (as some ucode even for non-BT devices
will in fact use BT statistics).
Warn upon encountering a statistics command from the
ucode that isn't known, so we will find such issues
earlier in the future.
