Description Sven Gothel 2014-02-20 17:39:07 CET

We already have several locations where bitstream operations are required and 
partially implemented (JPEG decoder, media parsing, ..)
as well as endian related conversion (elf parser, ..).

Create a versatile Bitstream class allowing:
  - Utilize I/O operations on I/O streams, buffers and arrays
  - Consider MSBfirst / LSBfirst mode
  - Linear bit R/W operations
  - Bulk R/W operations w/ endian related type conversion
  - Allow mark/reset and switching streams and input/output mode
  - Optimized operations

   Use Bitsream class for jogamp.common.os.elf.**

  Use Bitsream class for JPEGDecoder

  Refine Bitstream API 'signed' and 'unsigned' semantics - readUInt32(..) must return long due to EOF

Adapt:
