[dpdk-dev] [PATCH v3] scripts: add git hook scripts for checkpatch and auto doc generation

[Ferruh Yigit <ferruh.yigit@intel.com>]

These scripts are to automate some common tasks, scripts needs
to be deployed to specific folder to become active.

Scripts:
post-commit: Triggers after commit complete, re-generates api and
guides html documents. "RTE_DOC_OUT" environment variable configures
document output folder. Same script can be used on server side with
name "post-update", so documentation can auto updated after each push
to server.

post-merge: Same script as "post-commit", but triggered after git pull

pre-commit: Does a checkpatch check before commit started. This script
relies on scripts/checkpatches.sh script. checkpathes.sh should be
running well to use this git hook script.
This script can bypassed by commit "--no-verify" argument.

Deployment:
To make scripts active they need to be in <dpdk>/.git/hooks folder.
Alternatively "deploy.sh" script can be used, it simply links all
scripts into proper folder. Script names are significant and
shouldn't changed.
