COMP: Fix wrapping configuration warnings about itkMeshBase, etc.

Perform wrapping for the Mesh with the float and double types.

Commented out code about QuadEdgeMesh wrapping has been removed.  Wrapping
of Mesh classes over QuadEdgeMesh should occur within the QuadEdgeMesh
module to avoid module dependency issues.

ENH: Prevent duplicate loading of dynamic libraries

Dynamic libraries should only be loaded once. This patch warns if
there is an attempt to load an existing dynamic library.

To simulate duplicate loading, the patch modifies the arguments to an
existing test. The test argument passes in multiple paths that are
concatenated into a ITK_LOAD_PATH.

We had hoped to just pass in a single argument that had path
separators, but the window separator is a ";". We could not figure out
how to pass in an argument with embedded ;'s.

ENH:  Adding masking capabilities with confidence mask option.

This is the first of two commits aimed at improving the B-spline
image registration although this commit is an improvement in
and of itself.  This filter now has the option of specifying
a confidence mask.  This allows the user to specify the relative
weighting of the different points in the input displacement
field based on the values specified in the confidence mask
image.

BUG: Change default boundary condition to ZeroFlux

The WindoedSincInterpolateImageFunction with a constant boundary
condition produces an undesirable ring around the border of a
re-sampled image. By changing the default boundary condition to a
ZeroFluxNeumann the ringing is avoided, and unexpected results are
avoided.
PERF: Optimize loop index computations

A 10% speed-up in application using Dialation and Errosion was
achieved with these changes.

COMP: Remove unnecessary BORLAND code

A universally applied work around for the BORLAND compiler
was causing a compiler warning on Intel compiler where it was
validly detecting multiple declarations of the same forward
declared class across different scoping rules.

This patch removes the work around for the borland compiler,
simplifies the code, and removes a compiler warning when
extensive warnings are used with the Intel compiler.

COMP: Fix HDF5 unused function for long long on Unix.

Since long int provides the long long feature on Unix, this function
is unused, resulting in warnings on some compilers.

COMP: Fix compile error in PhilipsRECImageIO

The recent change 966fcb62c859229f9b421403c4faf3e6ef5e2b81 introduced
a compile error in PhilipsRECImageIO.  This was not detected because
no dashboards have this module enabled.
