bitbake: lib: implement basic task progress support

2016-07-08T08:57:26+00:00

For long-running tasks where we have some output from the task that gives us some idea of the progress of the task (such as a percentage complete), provide the means to scrape the output for that progress information and show it to the user in the default knotty terminal output in the form of a progress bar. This is implemented using a new TaskProgress event as well as some code we can insert to do output scanning/filtering. Any task can fire TaskProgress events; however, if you have a shell task whose output you wish to scan for progress information, you just need to set the "progress" varflag on the task. This can be set to: * "percent" to just look for a number followed by a % sign * "percent:" to specify your own regex matching a percentage value (must have a single group which matches the percentage number) * "outof:" to look for the specified regex matching x out of y items completed (must have two groups - first group needs to be x, second y). We can potentially extend this in future but this should be a good start. Part of the implementation for [YOCTO #5383].

Since we're going to make some minor extensions to it, it makes sense to bring in the latest version of python-progressbar. Its structure has changed a little but the API hasn't; however we do need to ensure our overridden _needs_update() function's signature in BBProgress() matches properly.
