3ee97e2206 staging: rtl8712: switch to common ieee80211 headers
This patch switches to <linux/ieee80211.h> and <net/cfg80211.h> and
deletes a lot of duplicate definitions plus many unused ones.

Non obvious changes:
- struct ieee80211_ht_cap is different enough that I preferred to keep
  (and rename) it for now.
- mcs_rate in translate_scan was not read after being set, so I deleted
  that part rather than using the renamed struct
- WLAN_CAPABILITY_BSS is replaced with WLAN_CAPABILITY_ESS which is the
  corresponding one with same value

15ea976a1f staging: rtl8712: Fix IEEE80211_ADDBA_PARAM_BUF_SIZE_MASK
The value in shared headers was fixed 9 years ago in commit 8d661f1e46
("ieee80211: correct IEEE80211_ADDBA_PARAM_BUF_SIZE_MASK macro") and
while looking at using shared headers for other duplicated constants
I noticed this driver uses the old value.

The macros are also defined twice in this file so I am deleting the
second definition.

5979afa2c4 staging: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

6cfed59848 staging: rtl*: Remove tasklet callback casts
In order to make the entire kernel usable under Clang's Control Flow
Integrity protections, function prototype casts need to be avoided
because this will trip CFI checks at runtime (i.e. a mismatch between
the caller's expected function prototype and the destination function's
prototype). Many of these cases can be found with -Wcast-function-type,
which found that the rtl wifi drivers had a bunch of needless function
casts. Remove function casts for tasklet callbacks in the various drivers.

b1198cca29 Staging: rtl8712: rtl8712_recv: fixed 80 character length warning
When the checkpatch.pl script was run, it showed lines with length
more than 80 characters in rtl8712_recv.c file. Fixed by
breaking it up into two lines within 80 characters.
