Add the SIGGEN_LOCKEDSIGS_TASKSIG_CHECK and
SIGGEN_LOCKEDSIGS_SSTATE_EXISTS_CHECK variables to replace
SIGGEN_LOCKEDSIGS_CHECK_LEVEL.
SIGGEN_LOCKEDSIGS_TASKSIG_CHECK will no control whether there is a
warning or error if a task's hash in the locked signature file doesn't match
the computed hash from the current metadata.
SIGGEN_LOCKEDSIGS_SSTATE_EXISTS_CHECK will control whther there is a
warning or error if a task that supports sstate is in the locked
signature file, but no sstate exists for the task.
Previously you could only have warning/errors for both controlled by
SIGGEN_LOCKEDSIGS_CHECK_LEVEL. This was an issue in the extensible sdk,
because we know sstate won't exist for certain items in the reverse
dependencies list for tasks. However, we still want to error if task
signatures don't match.

The previous message when signatures didn't match between the metadata
and the locked signatures file, the message output was a bit confusing.
Now the message should be of the form:
The zlib-native:do_install sig is computed to be
53531910a2a7848432da89def942a91a, but the sig is locked to
d25ba9035f7ccb308e51bbe1066e8d27 in SIGGEN_LOCKEDSIGS_t-x86-64
which will hopefully be more useful in understanding the problem.

With the extensible sdk we want there to be an error if a task tries to
run without signatures that match locked-sigs.inc. This patch enables
that error.

In order to support workflows using devtool where a user might want to
modify tasks that exist in locked-sigs.inc, there must be a way to unlock
recipes.
This patch adds that support by allowing the user to add recipes to
SIGGEN_UNLOCKED_RECIPES. Recipes that exist in that variable will have
all their tasks unlocked, as well as any tasks that depend on that
recipe.
For example if foo->bar->baz, if you unlock baz, it will also unlock bar
so that foo can be rebuilt without explicitly specifying bar as being
unlocked.

When a recipe is added to the workspace, the signatures for the tasks
will change. This means that bitbake must be told to allow the
signatures to be different if they are in locked-sigs.inc.
This is done by creating an unlocked-sigs.inc file which contains all
the recipes in the workspace each time devtool reads the workspace.
So not only will necessary things get added, previously added items will
be removed by virtue of them no longer being in the workspace.
This also makes sure that the extensible sdk picks up unlocked-sigs.inc
as part of the configuration.
