build,travis: add script from openwrt/packages.git

[aparcar]

add .travis.yml and a slightly modiefied .travis_do.sh to fit the
luci.git repository structure.

Builds all changed packages of the applications/ folder.

Script is adapted from openwrt/packages.git based on @lynxis work.

Changes of script are mostly:

• 68: PKGS var is set differently due auto versioning of luci packages
• 88: use Githubs openwrt/packages.git as feed
• 101, 112: no need to parse pkg_name
• 186: use different first commit hash

• line 101/112: why do you removed it?
  It's set via line 68, no need for any further modifications.

@jow-
any thoughts on activating travis also here in LuCI, like on packages feed?

@lynxis @champtar
Any further comments from the travis specialists?

[lynxis]

@aparcar why do you want to filter the files? Do you have any example when the script would otherwise fail?

[aparcar]

@lynxis the other folders do not contain Makefiles so I thought no packages can result -> nothing to build

[aparcar]

@lynxis please see line 188. It reads the first commit id so it could be used for packages.git as well.

[lynxis]

@aparcar LGTM. Do you tested it?

[aparcar]

@lynxis yes I created this rather useless PR for testing. It changes packages/files at different locations. The scripts finds all changes correctly.

[lynxis]

thanks for your work!

[champtar]

Hi @aparcar
Just want to double check that the FIRST_COMMIT_ID works in all cases.
Also maybe we can make this script generic enough to share it between repos?

[aparcar]

@champtar what do you mean with all cases? I tried it and it works as (I) expected.

I started on a more generic approach but it got a bit messy as https://github.com/openwrt-routing/packages uses a different structure/depth of packages.
There where some ideas about merging to openwrt/packages but stopped for a while openwrt/routing#184

I think this could be closed because of

@feckert thanks for reviewing, when I created the other PR I totally forgot about this one!
