tools lib traceevent: Add mac80211 plugin
Backporting mac80211 plugin.
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This plugin adds changed field resolving for
mac80211:drv_bss_info_changed tracepoint event.
The diff of 'perf script' output generated by old and new code:
(data was generated by 'perf record -e 'mac80211:drv_bss_info_changed' -a')
--- script.mac80211.old
+++ script.mac80211.new
- ifconfig 3711 [000] 1290.446492: mac80211:drv_bss_info_changed: phy0 vif:wlan0(2) changed:0x309f
+ ifconfig 3711 [000] 1290.446492: mac80211:drv_bss_info_changed: phy0 vif:wlan0(2)

Omitting the mac80211:drv_config tracepoint handling because the kernel
tracepoint changed its prototype and the plugin handler is no longer
working.
