Update to 4.1.3:

--- 4.1.3 2011/01/27

Update yaz.spec to operate on both SLES11 / Centos 5.5.

RPM: Release includes 'indexdata' name. Use indexdata in release name so
this package can be distinguished from other vendors.

yaz-config: Use exec_prefix, libdir, includedir .  Use these variables
as determined by configure

yaz-config: set YAZ_VERSION env. php_yaz relies on it.

GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
returns no error and no record, the present request is considered
partial (only a subset of the records could be returned by backend), and
so it is appropriate to set Present Status to partial-4.
