backports: add led_trigger_blink{_oneshot}()

Upstream commit: d38bcbb3b440de751e1b76a3c528feec96921d36

When led support is deactivated in the kernel and
CPTCFG_BACKPORT_BUILD_LEDS is set mac80211 references
led_trigger_blink_oneshot() but it is not declared anywhere.

This fixes the following build error:
net/mac80211/led.c: In function 'ieee80211_led_rx':
net/mac80211/led.c:25:2: error: implicit declaration of function 'led_trigger_blink_oneshot' [-Werror=implicit-function-declaration]

backports: update sch_fq_codel_core.c

Upstream commit: 4845ca0dd8ae26492de80756665f898a240b6c02

This brings sch_fq_codel_core.c to the version used in kernel 3.14-rc1.
Most of the changes were done many kernel versions before 3.14-rc1, but
in kernel 3.14-rc1 net_random() was removed and not it does not even
compile any more.
