Release osm2pgsql 0.84.0

Release version 0.82.0

[osm2pgsql] Enable 64bit IDs by default

Databases generated in 64bit and 32bit ID mode are not compatible with each other,
including applying diffs.

It is therefore necessary to reload the database to switch from 32bit ID mode to 64bit.

Also bump version number to 0.81.1

rename osm2pgsql-64 to osm2pgsql. this is now the new default branch.

a define in osmtypes.h has been commented out so that it builds for 32bit IDs
by default. bumped version to 0.80. 
todo: add 32/64 bit distinction to build process

* improved configure setup (including automake and libtool)

* support for different input readers besides libxml2 OSM XML parsing
* "primitive" XML parser integrated into the main binary
* OSM PBF parser
