Algorithms don't have to be split to prepare/process/postProcess
...
Since it's safe to evaluate parameters in background threads
now, it's usually going to be ok to evaluate everything in
the processAlgorithm step.
This keeps the algorithm code as simple as possible, and will
make porting faster.
Note that the prepare/postProcess virtual methods still exist
and can be used when an algorithm MUST do setup/cleanup work
in the main thread.

Avoid QgsFeedback flooding progress report signals
...
We only emit the progress changed signal when there's been at
least a 0.1% change since the last progress report. Otherwise
it's possible that things like processing algorithms which
are reporting feedback every feature in a 500k feature dataset
cause a gazillion signals to be emitted and everything to
slow to a crawl
