Instead it should just default to Autodetect
Given how the algorithm uses this parameter this change does not
result in any difference to scripts/etc running this tool, as
before/after this change the algorithm will use Autodetect mode
when the parameter isn't specified explicitly.
This just avoids the confusing situation where both "Not specified"
and "Autodetect" were exposed as options for the geometry type
parameter in the UI, with both having the same result.

The crash here is coming from sip internals -- somewhere it is
triggering a Python SystemError. I can't solve this one, so just
port the algorithm to c++ and deal with the much improved performance
instead.
At model debug log level we'll show all the generic
logs for step preparation, inputs and outputs for every
child algorithm, including those which we normally skip
(eg raise warnings/outputs, string concatenation, etc).
This gives model designers more useful information to
debug their models.
Use this new log level when running models through the
model designer window.

We were passing a float to a PyQt method requiring int in newer
Python versions, which raises an exception instead of silently
truncating.
SIP is totally messed up here -- the dialog wrapper or something
is always prematurely cleaned which results in broken QObject
connections throughout.
Hack around this by storing dialog instances in a global list to
prevent too early wrapper garbage collection
digital elevation model in order to classify pixels into ground
and non-ground cells
This is a port of the SAGA "DTM Filter (slope-based)" tool to a native
QGIS algorithm.
It also serves as a nice reference algorithm for raster based tools
which operate on a neighbourhood of pixels.
A shapefile can have a .cpg file to determine its encoding.
However, in processing, this file is not created when the
encoding is set to the magic "System" value.
This PR aims to propose to automatically determine the system
encoding using QT's codecForLocale.
So, even when using the magic "System" value, the cpg file
will be created with the true system encoding name.
