[svn-r28138] Add first support for _Bool and make hbool_t a "real" _Bool if available

Fix tests accordingly and fix misuse of hbool_t in various places

Fix initialization of H5Pgcpl/ocpl structs in property decoding routines

Tested on:
    Linux/32 (jam)
    Linux/64 (platypus)
    Linux/PPC64 (ostrich)
    MacOSX/64 10.11
