Implement GetUserAttributes in the InfoPipe

This patch adds support for requesting user data in the sysdb via
the InfoPipe. It currently has support for reading defined entries
of integral, floating-point or string types.

Tasks remaining:
1) Implement call to the provider when cache is out of date
2) Support byte arrays for userpic and similar

I modified sysdb_search_ctx in sysdb_search.c to accept an array of
attributes to pass into the LDB search.

I also made one additional related fix: the btreemap now sorts in the
correct order. Previously I had accidentally transposed the two
values for sorting, so the map would always have been in exact
reverse order.
