net80211: prefix get_random_bytes() with net80211_

Both linux/random.h and net80211 have a function named
get_random_bytes(). With overlapping files included these collide.
Arguably the function could be renamed in linuxkpi but the generic
name should also not be used in net80211 so rename it there.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Add a DFS debugging mode which is useful when doing automated DFS
compliance testing.

In order to allow for radar pattern matching to occur, the DFS CAC/NOL
handling needs to be made configurable. This commit introduces a new
sysctl, "net.wlan.dfs_debug", which controls which DFS debug mode
net80211 is in.

* 0 = default, CSA/NOL handling as per normal.
* 1 = announce a CSA, but don't add the channel to the non-occupy list
(NOL.)
* 2 = disable both CSA and NOL - only print that a radar event occured.

This code is not compiled/enabled by default as it breaks regulatory
handling. A user must enable IEEE80211_DFS_DEBUG in their kernel
configuration file for this option to become available.

Add 802.11h quiet time element support into net80211.

This supports both station and hostap modes:

* Station mode quiet time element support listens to quiet time
IE's and modifies the local quiet time configuration as appropriate;
* Hostap mode both obeys the locally configured quiet time period
and includes it in beacon frames so stations also can obey as needed.
