[svn-r16279] Description:
Bring revision 16278 back from revise_chunks branch:
Update layout information in DCPL to unify all information in one
underlying property and switch to using H5O_layout_t for storing it, which
simplifies things considerably.
Also, fix many compiler warnings.
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
(Original patch tested on many machines)
