Update to 2.2.0

Disable address standardizer, which seems to build if some of what it
requires (pcre) happens to be installed, until I figure out if it should
be built and require the dependencies.

Add patches (already reported upstream) to work around upstream using
PERL from pgxs, which is "missing" in pkgsrc, because the
postgresql-client build didn't require perl, and to use @PERL@, found
by postgis configure instead.

Passes tests on NetBSD-6 i386 with postgresql93.

PostGIS 2.2.0
2015/10/07

* Important / Breaking Changes *

  - PROJ4 4.6 and higher only
  - #2703, KNN <-> operator now returns the correct distance ordering
          for all geometry types, not just for points. Code that expects
          the looser "centroid distance" ordering should be updated.
  - #3022, ValidateTopology swapped meaning of id1 and id2 for the
          'edge crosses node' error (now edge_id,node_id)
  - #2565, ST_SummaryStats(tablename, rastercolumn, ...) uses
          ST_SummaryStatsAgg()
  - #2567, ST_Count(tablename, rastercolumn, ...) uses ST_CountAgg()
  - #2842, raster - Hide unselectable tables from raster_overview
        and raster_columns
  - By default, PostGIS raster disables all GDAL drivers affecting
    out-db rasters, ST_FromGDALRaster() and ST_AsGDALRaster() variants
  - #3181, POINT EMPTY is now stored as POINT(NaN NaN) in WKB, instead of as MULTIPOINT EMPTY
  - Java binding moved to separate repository:
    https://github.com/postgis/postgis-java
