bitbake: bitbake: add -C option to invalidate a task and rebuild the target

Browse Source 
This new command line option forces the specified task and all dependent
tasks up to the default task to re-run. This means that the following
single step:

bitbake -C compile somerecipe

is equivalent to the following two steps (with the recent change to -f):

bitbake -c compile -f somerecipe
bitbake somerecipe

Note that to work this option needs full hashing enabled (i.e.
BB_SIGNATURE_HANDLER must be set to a signature handler that inherits
from BasicHash). If this is not the case, -C effectively does nothing.

Based on a previous implementation of this option by Jason Wessel
<jason.wessel@windriver.com>.

Implements [YOCTO #2615].
