use same field expression in feature queries and min()/max()/distinct.
char fields were trimmed differently otherwise.

- allow editing of where clause in database selection dialog
- don't open query builder with invalid layer
- reallow oid type as primary key type
- preset where clause with current one in query builder
- actually show error message when QgsPostgresProvider::getGeometryDetails() fails

- add query support for OGR and spatialite layers (additional to postgres)
- QgsDataProvider::setSubsetString() now returns if the query is successful.
- add optional parameter to limit number of values returned from QgsVectorDataProvider::uniqueValues()
- rename QgsDbSourceSelect to QgsPgSourceSelect, use QgsVectorLayer for layer queries and make it wider
- QgsDataSourceURI: improve quoting
- fix relative path support for SpatiaLite on windows
- rename QgsPgQueryBuilder to QgsQueryBuilder and use QgsVectorLayer for
queries instead of postgres
cleanups:
- rename QgsServerSourceSelect to QgsWMSSourceSelect

- only use typlen for char fields
- use subset string when checking for key uniqueness and recheck in setSubsetString() (fixes#1933)

- postgres provider: report field width -1 for everything except strings (fixes#1131)
- in vector file writer, ogr provider choose field width:
- 255 for strings, when given width is negative or larger.
(was 80 in ogr provider and OGR determined-default for vector file writer).
- 10 for integers, when given width is negative or larger.
- 32 for reals, when given width is negative or larger.

- don't link GSL's CBLAS. We don't use it.
- don't link GEOS and GDAL into python bindings. They don't use them directly.
- link libdl on unix when internal spatialite is used
- update SONAMEs
- fix some warnings and typos

All providers should have now correctly set capability for fast access to features by id (SelectAtId).
Until now, attribute table was using memory model for Postgres provider (i.e. very slow open)
From now it uses the "good" model, so the attribute table opens much faster.

- update vector data providers accordingly
- postgres provider:
- add support for more native types and setting of column comments
- catch errors on retrieval of defaults values (fixes#1713)

- handle secondary geometry columns as text in EWKT.
- improve handling of errornous queries.
- kudos to Stefanie Tellex for the initial patch

- more API cleanups
- single click (instead of drag) to select a feature (fixes#1154)
- fixes for topological editing
