removal of C++isms from libabrt, part 1

This patch converts libabrt usage of C++ map<string, string>
to a glib-based container, GHashTable.

It is typedef-ed to map_string_h.
We can't typedef it to map_string_t, since other parts of ABRT
(daemon, cli) still use that name for C++ container.

Also, exceptions are removed everywhere.
