A locking problem was found in routine _rtl92ee_cmd_send_packet() that led
to system freezes. Upon inspection, several drivers had the same problem;
however, the routines all used the same code. The common code has been
moved into rtlwifi.

Realtek released new drivers on 06/28/2014. These changes implement all their
changes into the kernel version of the driver. In addition, these modifications
are part of the process of unifying the Realtek and kernel code bases.

This patch updates the driver to match the latest Realtek release, and
it is an important step in getting the internal code source at Realtek to match
the code in the kernel. The primary reason for this is to make it easier for
Realtek to maintain the kernel source without requiring an intermediate like me.
In this process of merging the two source repositories, there are a lot
of changes in both, and this commit is rather large.

This driver was entered into staging a few cycles ago because there was
not time to integrate the Realtek version into the support routines in
the kernel. Now that there is an effort to converg the code base from Linux
and the Realtek repo, it is time to move this driver. In addition, all the
updates included in the 06/28/2014 version of the Realtek drivers are
included here.
With this change, it will be necessary to delete the staging driver. That
will be handled in a separate patch. As it impacts the staging tree, such a
patch is sent to a different destination.

When the rtlwifi family of drivers was converted to use a workqueue when
entering or leaving power save mode (commits a269913c52, a5ffbe0a19,
41affd5286, b9116b9a2b, and 6539306b2c), the code began scheduling work from
the callback routine of a different workqueue with a resulting increase in
overhead.

Macros CL_SNPRINTF and CL_PRINTF are always used in that order. The first
formats info into a buffer, and the second dumps it with printk. As the
debug system in rtlwifi has a macro that does this with a single call,
it seems reasonable to use it instead. An additional benefit is that the
debug level can be set when loading the driver used by the wifi device.

The 0-DAY kernel build testing backend reports the following warning:
drivers/net/wireless/rtlwifi/btcoexist/halbtcoutsrc.c:516 halbtc_bitmask_write_1byte()
warn: always true condition '(bit_mask != 4294967295) => (0-255 != u32max)'
This problem was introduced in commit ed364abffd6e19bec67b7ccda8237213b8b37640,
and arises because the caller of halbtc_bitmask_write_1byte() is using a
u8 rather than a u32 for the data.
