Update osm2pgsql to 0.92.1

Release 0.92.1
	This fixes two important bugs which impacted relations with
	excessive members and consuming updates with the multi backend

Release 0.92.0, a new stable branch
	Major changes since 0.90.0 are

	- PostgreSQL 9.1 + PostGIS 2.0 or later are now required, which has
	  allowed performance improvements and cleanups
	- EPSG 3857 is now default. You can get the old behavior by manually
	  specifying 900913
	- Invlid geometries are re-checked for validity after buffering, instead
	  of assuming GEOS returns a valid geom

	Other changes are
	- A new option to change the max bbox size at which polygons will expire
	  all the tiles in them, not just the boundary
	- Behavior fixes for C transforms and tables with no columns
	- More numeric datatypes are allowed for table columns in C tagtransforms
	- Lua is now required by default
	- Code fixes, particularly replacement of C memory management
