Create columns only for the first value, support null (not clear how supported in the rest of the code), test

More tests, fix optional aggregation and multiple column creation

Create and update all columns at once

Create transaction in a function

Support direct SQL as a backend besides v.db.univar. Handle cleanup from the main function. Remove global variables. Use PID and node name for the temporary vector.

Functions for common aggregation functionality; shorter code. Simplify dev null in cleanup code. Modernize and Pylint generic error message.

Test for dissolve/merge of areas without shared boundaries.

Support any layer, not just 1

Do not generate all combinations when all options are provided, add documentation

Remove duplicate columns and methods for non-explicit automatic (interactive) result column handling

Support SQL expressions as columns (as in v.db.update query_column or v.db.select columns)

Support also text-returning aggregate function such as SQLite group_concat.

Support general SQL syntax just like v.db.select for the price of less checks. Now depends on v.db.select producing the list of column names OSGeo#3090 . Test and example included.
