Implement direct and reverse map lookups.
Not all maps support reverse lookups generically (for
example, gdbm does not), therefore introduce a new
"bidi" (bi-directional) map, which is a compound of
two maps, each one used for a particular lookup direction.
* lib/Makefile.am (maps): List all maps here.
* lib/bidimap.c: New file. Implementation of a
bi-directional map.
* lib/filemap.c: Update to the changes in API.
Implement reverse lookup.
* lib/gdbmmap.c: Update to the changes in API.
* lib/nullmap.c: Likewise.
* lib/seqmap.c: Likewise.
* lib/ldapmap.c: Update to the changes in API.
Implement reverse lookup.
New configuration keywords: reverse-filter, reverse-attr.
* lib/libeclat.h (eclat_map_drv) <map_get>: Change signature,
take search direction as a new argument.
(eclat_map_get): Likewise.
(eclat_map) <eclat_map_bad_dir>: New status code.
(MAP_DIR, MAP_REV): New macros.
(eclat_map_name_split): New function.
(eclat_map_drv_bidi): New extern.
* lib/map.c (eclat_map_get): Change signature,
take search direction as a new argument.
Pass new keyword to the "key" translation: "dir".
(eclat_map_strerror): Handle new status code.
(eclat_map_name_split): New function.
* src/eclat.c (main): Register eclat_map_drv_bidi.
* src/util.c (translate_ids): Use eclat_map_name_split
to obtain direction code from the map name.
(translate_resource_ids): Use direct lookups.
* tests/Makefile.am: Add new testcases.
* tests/testsuite.at: Likewise.
* tests/bidimap.at: New testcase.
* tests/filemap.at: Test reverse lookups.
