combo-layer: allow splitting out local config
Allow splitting the local parts of the configuration (mostly
local_repo_dir and last_revision, although there is no limitation) to
a side-by-side -local.conf file, with component sections optionally
tagged with the combo layer branch name. This effectively allows you to:
* avoid polluting the history by committing the updated last revision
to the combo repository for every update
* avoid putting local repo paths into the combo repository
* manage multiple branches of the combo repository whilst avoiding the
possibility of mixing the configuration for one branch with another.
An example split configuration (note, values may be artificial):
------------------- combo-layer.conf -------------------
[bitbake]
src_uri = git://git.openembedded.org/bitbake
dest_dir = bitbake
hook = scripts/combo-layer-hook-default.sh
[oe-core]
src_uri = git://git.openembedded.org/openembedded-core
dest_dir = .
hook = scripts/combo-layer-hook-default.sh
--------------------------------------------------------
---------------- combo-layer-local.conf ----------------
[bitbake]
local_repo_dir = ../repos/bitbake
[oe-core]
local_repo_dir = ../repos/oe-core
[bitbake|master]
branch = master
last_revision =
db689a99beffea1a285cdfc74a58fe73f1666987
[oe-core|master]
branch = master
last_revision =
121a1499a81706366acc0081272a6bff634d4d62
[bitbake|denzil]
branch = 1.12
last_revision =
24b631acdaa143a4de39c6e1328849660c66f219
[oe-core|denzil]
branch = denzil
last_revision =
741146fa90f28f7ce8d82ee7f7e254872d519724
--------------------------------------------------------
It is assumed that the local config file will be added to .gitignore.
