Optimize lookup of EPSG projection codes

Description (last modified by dmorissette) (diff)
A few weeks ago I was doing some benchmarks with MapServer 4.10 on a mapfile with about 10 layers in it and replacing the 10 "init=epsg:xxxx" defns with native PROJ.4 definitions made the WMS GetCapabilities requests go from 3 hits/seconds to 12 hits/seconds (4 times faster!). Since EPSG codes are used a lot by all OGC services, optimizing the EPSG lookup (or caching them at a minimum) is something that would be very valuable for all OGC service users.
