bitbake: build: implement custom progress handlers injected via OE_EXTRA_IMPORTS
A separate patch to base.bbclass (in poky) will add the OE_EXTRA_IMPORTS variable. The contents are appended into OE_IMPORTS. This provides a mechanism by which layers (in their layer.conf) can make custom progress handlers available. As a backup, individual recipes can inject progress handlers into __builtins__. Custom handlers are expected to have this __init__ signature: def __init__(self, d, outfile=None, otherargs=None): Recipes can then use the handlers like this: do_task[progress] = "custom:mylayer.util.ProgressHandler[:args]" The last part (everything after and including the second colon) is optional. If provided, it is passed to HandlerClass's __init__ as otherargs="args". Otherwise, otherargs=None.
