fb811766f8 Add framework for algorithm outputs 
This somewhat changes the meaning of outputs from processing 2.x.
In 2.x processing outputs were used both as a method of specifying
inputs to algorithms (file paths to destination layers created
by the algorithm) AND pure outputs (such as statistics calculated
by the algorithm).

This is now split. The old input-type-outputs (destination layers)
are now input parameters (since the parameter value IS an input to the
algorithm). To differentiate them from parameters indicating pure
input layers a new "isDestination()" method was added to
QgsProcessingParameterDefinition.

Output definitions are now purely indications of values CREATED
by the algorithms. Suitable candidates are the existing calculated
stats and actual file path/URI of any layers created by the algorithm.
Moving forward we should ensure all algorithms output as much
useful information as possible - e.g. number of features processed,
number of skipped features, count null geometries encountered, etc...

56c8baaccb Provide a standard string comparison method in QgsLocatorFilter 
Subclasses should use this method instead of directly calling
QString::contains or using Python 's in search' type matches.
This ensures consistent matching behaviour across different filters.

6649d2b1ed Sort filter results so closer matches appear higher 
A closer match means more of the text is matched, ie
a short string inside a long string is penalised

102a46662b Implement prefix based locator searching 
Filters can indicate their preferred search prefix. Searches which
begin with this character will be restricted to the single matching
filter.

E.g. entering 'l buffer' will searching only layers containing 'buffer'

Other prefixes are:
- . search actions
- pl search print layouts
- a search algorithms

Plugins are restricted to a minimum 3 character prefix. We do this
to avoid plugins 'stealing' desirable prefixes, and instead we
want to reserve them for future core filters.

b33ce0bf47 Allow speciyfing the priority for filters 
Higher priority (i.e. more important) filter results get shown
first. This means filters like project layers & composers will
show above 'cruder' filters like the actions/processing filters.
