textproc/xmlada: Update to 26.0.0
Update to 26.0.0:
- Complete License block
- Convert to GPRBuild, which enables removal of gmake (except from do-test), GNU configure and cleans up the file system hierarchy in ${PREFIX}
- Install Sphinx generated manual page
- Install Ada Library Information files (.ali) into ${PREFIX}/libdata/xmlada instead of in ${PREFIX}/lib/xmlada, this respects the default layout described in hier(7)
- Integrate testing, including the W3C's XML test suites
- Some minor updates to pkg-descr
- Remove hard dependency on GNAT-12 from ${USES} and ${NO_SHLIB_REQUIRES_GLOB} enabling XML/Ada use for any of the GNAT tool-chains
