gentree: use git library to speed up --git-revision

If the git library is available (on many distros, just
install python-git or similar) then use it to read the
git blobs from disk if --git-revision is used.

On my system (with an SSD) this speeds up the entire
backport generation process significantly (when using
--git-revision):

before:
real 0m39.280s
user 0m13.464s
sys 0m16.644s

after:
real 0m22.554s
user 0m16.404s

python support: rename git library to bpgit

There's a python git library, and our name conflicts
with it since it's also just called "git". I want to
use the python library (optionally) to speed up the
git accesses so this is now relevant.

compat: backport soc_camera_power_[on|off] for 3.3

We are only backporting CONFIG_SOC_CAMERA for kernels >= 3.4
but there is an exported symbol from there that some media
drivers that we do support on 3.3 need. Handle this special
case.

SOC_CAMERA is only enabled on 3.4 as it depends on some
newer regulator functionality, however there are some SOC
cameras that can rely on the 3.3 regulatory built-in core
and the 3.3 SOC_CAMERA module however two routines are
not exported in that version of SOC_CAMERA that newer
SOC cameras do require. Backport that functionality.

Technically this should go into <media/soc_camera.h>
given that is where its where its exported on linux-next
but in practice only placing it on <linux/v4l2-mediabus.h>
actually fixes linking errors for 3.3 for all SOC camera
drivers we make available for 3.3:

compat: fix dma_common_get_sgtable() backport placements

be available to older kernels as of 3.6 but it was only
up to 3.8 where it was detangled from depending on
CONFIG_HAVE_GENERIC_DMA_COHERENT. Its a mess to express
this on compat files so just word it via kconfig and throw this

we may need to backport later with the same circumstances.

One last hack was required for 3.3-3.6 and that is due
to header changes between kernels.

backport: allow using backported drivers w/o LEDs

When the base kernel has LED support (partially) disabled,
currently many drivers cannot be built. Since LED support
is hardy critical, work around this by providing API stubs
