4da1ce8404 Drop redundant virtual keywords on overrides 
Run clang-tidy modernize-use-override to remove all the redundant
virtual keywords from overridden methods, and add some missing
overrides.

Another benefit is that this has also added the overrides
on destructors, which will cause a build failure if a base
class is missing a virtual destructor.

4ae9241e71 [processing] Allow providers to determine default vector/raster file 
to use for their algorithm's parameters

Because some providers do not have support for all output types,
we need to give providers a way to restrict the default format
choices to those which are supported by the provider.

6afe25ef0f [processing] Proper progress reports during model execution 
Instead of showing the progress reports for each child algorithm
individually, which leads to repeated 0->100% progress for every
step of a model, we proxy the progress reports and account for the
overall progress through a model as well. This means that
the progress accounts for both the progress within the current
model step AND the total number of steps left to execute.

383422f069 Fix "wrapped object has been deleted" errors in Processing 
Ownership of Python subclass algorithm instances was getting
mangled due to passing through multiple functions with /Factory/
annotations.

As per Phil Thomson's advice on
https://www.riverbankcomputing.com/pipermail/pyqt/2017-July/039450.html:
"
/Factory/ is used when the instance returned is guaranteed to be
new to Python. In this case it isn't because it has already been
seen when being returned by createInstance(). (However for a different
sub-class implemented in C++ then it would be the first time it was seen
by Python so the /Factory/ on create() would be correct.)

You might try using /TransferBack/ on create() instead - that might be
the best compromise.
"

Changing to /TransferBack/ indeed fixes the error for me.
