Changes 4.7.0:
* Added in memory caching of init file search results for substantial
  acceleration in some application environments (like MapServer).
* Regenerated nad/epsg init file with EPSG 7.1 database, including new
  support for Google Mercator (EPSG:3857).
* Various thread safety improvements, including preliminary support for
  a mutex lock around some operations, like grid loading.

Remove @dirrm entries from PLISTs

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Update to 4.6.1.

4.6.1 Release Notes
-------------------

 o Upgraded to EPSG 6.17 version for nad/epsg.  Also corrected the precision
   problem introduced in the last version.

 o Added logic for tmerc projection to fail rather than return crazy results
   if more than 90 degrees away from the central meridian (#5).  This change
   may only be temporary till a more comprehensive solution is found.

 o Fixed handling of extra text in cs2cs.

 o Renamed INSTALL to INSTALL.TXT.

 o The eqc projection has been generalized to include a latitude of origin.

 o Added the glabsgm (Gauss Laborde / Sphere Geometric Mean) projection,
   and gstmerc variation.

 o nad/IGNF init catalogue created.

 o added the ntf_r93.gsb datum shift file.

 o Add /Op in nmake.opt compile options to avoid VC7 optimization bug (#12)

 o Fix testvarious test script so it works properly when grid files available

Update to 4.6.0.  NOTE ESPECIALLY the behavior change in the first
bullet below.

4.6.0 Release Notes
-------------------

 o MAJOR: Rework pj_transform() to avoid applying ellipsoid to ellipsoid
   transformations as a datum shift when no datum info is available.

 o Avoid applying "change of ellipsoid" during datum shifting based on
   ellipsoids getting changed to spheres for spherical projections.

 o Upgrade to EPSG 6.13

 o Added "900913" "Google Mercator" code in nad/esri.extra.

 o Avoid some static variable based multi-threading problems.

 o Improve error recovery if ctable style datum shift grid fails to load.

 o Support drive letters properly in PROJ_LIB paths for win32.

 o Fix occasional problem with DMS parsing.

 o Removed non-functional mpoly projection.

 o add lonlat, and latlon as aliases for longlat.
