In MultiStageProgressReporter, set a guard when we start the progress
so that it can't happen more than once. This fixes "Initialising
tasks.." being shown twice in succession when running bitbake in
non-interactive terminal mode.

Implement progress reporting support specifically for the fetchers. For
fetch tasks we don't necessarily know which fetcher will be used (we
might initially be fetching a git:// URI, but if we instead download a
mirror tarball we may fetch that over http using wget). These programs
also have different abilities as far as reporting progress goes (e.g.
wget gives us percentage complete and rate, git gives this some of the
time depending on what stage it's at). Additionally we filter out the
progress output before it makes it to the logs, in order to prevent the
logs filling up with junk.
At the moment this is only implemented for the wget and git fetchers
since they are the most commonly used (and svn doesn't seem to support
any kind of progress output, at least not without doing a relatively
expensive remote file listing first).
Line changes such as the ones you get in git's output as it progresses
don't make it to the log files, you only get the final state of the line
so the logs aren't filled with progress information that's useless after
the fact.
Part of the implementation for [YOCTO #5383].

The init function of the parent class fires a progress event for 0
progress rather than a start event. UI code was assuming that progress
events should always have a start event first. This change ensures that
the start event is correctly generated.
This fixes crashes that were seen in knotty in some configurations.

When "Preparing RunQueue" shows up you can expect to wait up to 30
seconds while it works - which is a bit long to leave the user waiting
without any kind of output. Since the work being carried out during this
time is divided into stages such that it's practical to determine
internally how it's progressing, replace the message with a progress
bar.
Actually what happens during this time is two major steps rather than
just one - the runqueue preparation itself, followed by the
initialisation prior to running setscene tasks. I elected to have the
progress bar cover both as one (there doesn't appear to be much point in
doing otherwise from a user perspective). I did however describe it as
"initialising tasks".

Add a class to help report progress in a task that consists of multiple
stages, some of which may have internal progress (do_rootfs within
OpenEmbedded is one example). Each stage is weighted to try to give
a reasonable representation of progress over time.

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.
