[svn-r10931] Purpose: Adjust Test Program and Rename

Description: Renamed test/dt_atomic.c to test/dt_arith.c(an abbreviation
of "arithmetic data types") to better describe the program.  This checkin
broke down into three sections when the floating-point numbers are the
source, normalized, denormalized, and special values.  If there's any
difference of destination values, only normalized value test reports
failure.  The other 2 report only as warning.


Platforms tested: h5commitest and fuss

Misc. update: MANIFEST
