Linaro Android Media Create hardware pack config support

[milo, 2012-11-07] Hwpack v3 format: https://wiki.linaro.org/HardwarePacksV3
[milo, 2012-11-07] First draft of Android Hwpack syntax and fields: https://wiki.linaro.org/AndroidHardwarePacksV3
[milo, 2012-11-08] Linked branch with ongoing code work.
[milo, 2012-11-09] Spoke with Vishal: Android hwpack definition is OK, will update next week where to store the extracted board configurations (maybe in the same way as done with normal hwpack: a project in Launchpad with each board its own branch, accessibile by the Infrastructure and Android teams).
[milo, 2012-11-12] Extracted config values and created temporary repository at lp:~milo/linaro-infrastructure-misc/android-hwpacks
[milo, 2012-11-16] Continue work and refactoring: some tests still failing. Wrote email to the team to pick up work from here.
[dzin, Nov 20, 2012] Probably will not make this cycle, pushed out by vacation. To be retargeted to 12.12.
[vishalbhoj, 2012-11-22] Can we get the hwpacks templates/configs in git repository android.git.linaro.org. This way it will be easy for the team to update them the usual way through gerrit.
[milo, 2012-12-04] Discussed with Vishal on IRC: configuration files will be hosted and android.git.linaro.org, as suggested the location could be " device/linaro/hwpack".
[milo, 2012-12-04] Instructions on Gerrit and how to set up a project: https://wiki.linaro.org/Platform/Android/Gerrit
[danilo, 2012-12-28] Move to 2013.01, mostly completed in the Christmas week of 2012. However, considering the validation and testing we'll want to do, leaving for next cycle completely.
[milo, 2013-01-04] All code has been merged into trunk, validation tests have been done with l-m-c and l-a-m-c starting from release 12.12 down to 12.09, still ongoing tests being done with older releases.
[milo, 2013-01-04] Pinged also Vishal about testing the new features on boards different than panda.
[milo, 2013-01-07] Since l-a-m-c is backward compatible, it is not necessary to change anything on LAVA, as long as new boards are introduced.
[milo, 2013-01-07] Create also github branch with the config files to easily clone it: https://github.com/MiloCasagrande/android-hwpacks (I cannot create repositories in the Linaro GitHub group).

Meta:
Headline: Provide support for an Android hwpack configuration file that holds Android board parameters to be used with linaro-android-media-create.
Acceptance: A new Android hwpack configuration format is defined based on the existing hwpack format v3. Actual board configurations are extracted from the code, and Android hwpack config files are provided. linaro-android-media create has been updated to use the config file. Backward compatibility is guaranteed.
Roadmap id: CARD-242
