bitbake: lib: implement basic task progress support
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:<regex>" to specify your own regex matching a percentage
value (must have a single group which matches the percentage number)
* "outof:<regex>" 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].
