[PATCH v2 7/7] Introducing fetchall, unpackall and unpack_debian tasks.

[Benedikt Niedermayr <benbrenson89@googlemail.com>]

- fetchall, unpackall:
These tasks offer the possibility for running fetch or unpack tasks for each recipe
in Isar.
After running bitbake "<image>:do_unpackall" Isar will fetch all sources and also unpack them into
related WORKDIRs.

In order to be able to apply the mirror prefetching mechanism, all debian control files must be available
for Isar (Build-Depends required). With all control files available do_cache_config() task should be able to collect
all Build-Depends.

- unpack_debian:
This task should be implemented within each recipe if needed. After the task has run the control file should be located at
${WORKDIR}/${SRC_DIR}/debian/control.
When fetching already debianized sources this task can be omitted.
Locating the control file at the correct position is needed for the dependency collector.
