IO/HDF/Makefile.PL - Add additional library detection case.

   if (-e "$libdir/libhdf.a" && !$found_df)
   {
       $found_df = 1;
       $hdf_lib_path = $libdir;
       $hdf_libs = '-lmfhdf -lhdf';
       print "Found libhdf.a at $libdir/libhdf.a\n";
   }

Thanks kmx.
t/gis_proj.t - Provide "datum" arg for pj_init_plus()

Absence of the "datum" arg can lead to error.
t/proj_transform.t - Provide "datum" arg for pj_init_plus()

Absence of the "datum" arg can lead to error.
t/proj_transform2.t - Provide "datum" arg for pj_init_plus()

Absence of the "datum" arg can lead to error.
t/Lib/GIS/Proj/Makefile.PL - Provide "datum" arg for pj_init_plus()

Absence of the "datum" arg can lead to error. (Thanks kmx)

Lib/Transform/transform.pd - Don't include sys/time.h (MS Windows only)

Including sys/time.h (line 1 of transform.pd) on MS Windows causes
compilation errors.
IO/Browser/Makefile.PL - additional fix to library detection (Thanks kmx)

scantree.pl and mkhtmldoc.pl were not being run for installs into vendor.
Thanks kmx.
Update Known_problems and Release_Notes for 2.007_03
Update VERSION to 2.007_04 for development
Add convenience blocks to silence 'use strict' warnings during 'make test'.
Some POD changes for datatypes.

Add a link from byte, ushort, etc to Datatype_conversions.
Add indx to the hard-coded CPAN-only datatype docs.
Upgrade t/primitive2.t to use Test::More

Also add some tests for one2nd. Not complete, but it is something!
Also fix a bug in this tapprox that gave the wrong return value.
Bug never triggered because all uses of tapprox here passed in scalars, not piddles.
one2nd returns piddles of indx datatype now.

Previously the first piddle returned would have the same datatype
as the input data (e.g., double) and the remainder would be of type
long. Now we cast the index piddle to indx first.

Added some POD to document this.
Fix CallExt for android build, sf.net bug #357

This fix was proposed by Brian Fraser.  Thanks.
Maybe we can add Android as an official PDL
supported platform.
