Make as much as possible static, and remove use of talloc_reference and
allocation/deallocation of memory when not necessary.
Fix also responder use of rctx->conn, was mistakenly used for both
monitor and dp connections.

This reduce code duplication as it allows to use one set of watch and timeout
functions, and at the same time also allow not to use a secondary structure just
to unify these functions.

Any client of the SBUS that wants to implement automatic
reconnection may now call sbus_reconnect_init to set it up.
The clients will need to set up a callback to handle the result
of the reconnection and (in the case of a successful reconnection)
readd the method handlers to the connection context.

SetUserAttributes is now available for use in the Infopipe.
I also reorganized a few of the internal InfoPipe objects to
reduce code duplication.
One very simple test is included in this checkin to validate that
the parser is working.

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1) Implement call to the provider when cache is out of date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.

sbus_message_handler is not responsible anymore for sending
back data in any case.
Transfer this responsibility to the handler function called.
This way both synchronous and asynchronous funstions use the
interface the same way and can properly free memory referenced
by the reply after the send buffer has been filled in and all
copies are done in sbus_conn_send_reply()

This reverts commit 13421cbe0af4343f9d110600755ffa756690b282.
Conflicts:
server/infopipe/infopipe.c
server/infopipe/infopipe.h
While this solution fixed the contingent memory problem it introduced
other problems in handling asynchronous replies.
Reverting in preparation for a different way to solve it.
Conflicts have been taken care of.

with D-BUS clients built in multiple languages. It will read in the XML file on the first request and store the returned XML as a component of the sbus_message_handler_ctx for the connection. All subsequent requests during the process' lifetime will be returned from the stored memory. This is perfectly safe, as the available methods cannot change during the process lifetime.

dbus_message_append_args() adds a reference to memory that is not
copied to the outgoing message until dbus_connection_send() is
called. Since we compile our reply messages in functions and then
return the reply, we need a mechanism for deleting allocated
memory after invoking dbus_connection_send. I have changed the
arguments to sbus_msg_handler_fn so that it takes a talloc ctx
containing the sbus_message_handler_ctx and a pointer to a reply
object. We can now allocate memory as a child of the reply context
and free it after calling dbus_connection_send.

sbus_method_ctx entries, meaning that the next connection to attempt to disconnect would receive a segmentation fault also trying to delete them. They are now talloc_reference()-ed to their connection context and talloc_unlink()-ed upon deletion.
I have also modified the sbus_new_server() call to take a reference
to an sbus_srv_ctx object as a return argument, so that the calling
function can keep track of the SBUS server context if it so chooses.

Fix memory hierarchy, set the destructor on the server context so
that it is called before any memory attached to it is freed. Before
this change a talloc_free() on the event context would end in a double
free and and an abort() inside talloc.

sbus_conn_ctx to all message handling functions.
This will allow connection-specific data to be passed in by taking advantage
of the sbus_conn_set_private_data() function on the sbus_conn_ctx struct.
Presently this private data is global to all methods of the connection context.
