Localpatch

This is just workprint. Feel free to contribute.

By default, localpatch will look into /etc/portage/patches in order to search for patches, it can be changed by setting LOCALPATCH_OVERLAY variable.

Priority in choosing right patches source

1. ${CATEGORY}/${PN}-${PV}-${PR} - example 'app-foo/bar-1.0-r1'
2. ${CATEGORY}/${PN}-${PV} - example 'app-foo/bar-1.0'
3. ${CATEGORY}/${PN} - example 'app-foo/bar'
