[Insight-developers] Update of GDCM library

[Mathieu Malaterre]

Hi,

	I have just updated the GDCM library from 0.6 branch to 1.0 branch. I 
also removed the GDCM option so from now on GDCM is always build as part 
of ITK.

	Changes include:

- Better big endian support (in particular for jpeg image)

- Full support of fragmented jpeg images (where jpeg stream was split in 
small chunks)

- Lots of API cleanup (remove the redundant gdcm at begining of functions)

- Complete removal of the accessors by DICOM name. This was considered 
dangerous since DICOM name is not guarantee to be unique, and the name 
could change from one revision to another. Not a notion of generelized 
key is used intead. Ex. insteasd of "Patient's Name", now you should use 
  "0010|0010"

- dicomDirV3.dic was update to also take into account the VM (value 
multiplicity).

- Enhance support for DICOMDIR file

- Partial support for Papyrus image (very close to Dicom V3 specification)

- Huge number of memory leaks were fixed.
