(Fdbus_call_method, Fdbus_send_signal): Apply type cast in
dbus_message_new_method_call and dbus_message_new_signal.
(Fdbus_register_signal): Rename unique_name to uname. Check
handler for FUNCTIONP instead of CHECK_SYMBOL. Handle case of
non-existing unique name. Fix typos in matching rule. Return an
object which is useful in Fdbus_unregister_signal.
(Fdbus_unregister_signal): Reimplementation, in order to remove
only the corresponding entry.
(Vdbus_registered_functions_table): Change the order of entries.
Apply these changes in xd_read_message and Fdbus_register_signal.
(Fdbus_call_method, Fdbus_send_signal, xd_read_message): Use
`unsigned int' instead of `uint'.
(xd_read_message, Fdbus_register_signal): Split expressions into
multiple lines before operators "&&" and "||", according to the
GNU Coding Standards.
registered handler. There might be several handlers registered
for the same signal.
(Fdbus_register_signal): Don't overwrite a registration for the
same signal. Add a new registration if handlers are different.
(Vdbus_registered_functions_table): Rework doc string.
(Fdbus_register_signal): Use DBUS_MAXIMUM_NAME_LENGTH and
DBUS_MAXIMUM_MATCH_RULE_LENGTH for string lengths.
(Fdbus_call_method, Fdbus_send_signal, Fdbus_register_signal):
Unify argument lists.
(xd_read_message, Fdbus_register_signal) Reorder and extend event
arguments and hash table keys. Use unique name for service.
(Fdbus_unregister_signal): Remove checks.
(Vdbus_registered_functions_table): Fix doc string.
Move check for Vdbus_registered_functions_table to
xd_read_queued_messages.
(xd_read_queued_messages): Protect xd_read_message calls by
internal_condition_case_1.
Qdbus_system_bus and Qdbus_session_bus, respectively.
(Vdbus_intern_symbols): Removed.
(Vdbus_registered_functions_table): New hash table.
(XD_SYMBOL_INTERN_SYMBOL): Removed.
(xd_read_message, Fdbus_register_signal, Fdbus_unregister_signal):
Rewritten in order to manage registered functions by hash table
Vdbus_registered_functions_table.
