[svn-r8423] Purpose: New feature

Description:  A new exception handler for datatype conversion(set through
H5Pset_type_conv_cb) to replace the old overflow callback function(set
through H5Tset_overflow).  This new handler can deal with overflow, precision
loss and fraction truncate during datatype conversion.


Platforms tested: h5committest

Misc. update:  release_docs
