Converts a raster layer into a vector layer, with a polygon feature
corresponding to each pixel from the raster and a single field
containing the band value from the raster.

It turns out that an empty QComboBox evaluates to False:
>>> t=QLineEdit()
>>> bool(t)
True
>>> c=QComboBox()
>>> bool(c)
False
Due to that, the 'TABLE' parameter was missing if its (editable) combo box was empty.
Original error - while updating an algorithm's parameters (gdal:importvectorintopostgisdatabaseavailableconnections)

existing folder match for a path
E.g. if \a path is "/home/user/projects/2018/P4343"
and "/home/user/projects" exists but no "2018" subfolder
exists, then the function will return "/home/user/projects".
(Suprisingly no existing Qt method for this!)
A pseudo color renderer was getting created in classify() but never deleted.

As a bonus switched a for loop from mixed constBegin()/end() usage to range for.
when clicking on ok of an attribute form, tell all embedded widgets (all
widgets actually) that we are going to close the form and it's the last
call to push changes to the edit buffer or they will be lost.
Fix#19137
message log critical/warning messages
These messages are still logged, but the log indicator is not
modified to flag their appearance.
This allows certain error messages to be logged (e.g. on startup)
which cannot be fixed by users/developers (e.g. those caused
by upstream Qt issues, 3rd party Python libraries, etc) but
without flagging them.
Currently, we get so many of these warnings on startup that the
log indicator loses all impact, and newly introduced, VALID
errors go unnoticed/ignored.
We never call this method using nullptrs, so there's no need
for this to be a pointer argument in the first place. And
having it a pointer encourages leaky code, such as the
leak this commit fixes in server.
