If user try to remove the last reference of proxy, object, connection
or eldbus(lib) inside of message callback it was causing the
eldbus_pending_dispatch() being called 2 times, one because of the
eldbus_cancel() that is triggered when the last reference of the
message parent is removed and another after the return of the user
callback.

Now we will remove the pending from parent pending list before
call the user callback, this way only the pending messages will
be canceled.
Also we need increase the eldbus reference before call
dbus_connection_dispatch() or user could remove the last reference of
eldbus inside of a message callback when we still are
holding one reference of the connection.

Summary: Fix Coverity CID1256952: reports a null derefence here due to
eldbus_message_new returning NULL, thus causing a null dereference
when trying to set reply->dbus_msg

Some problems with the actual implementation:
- the reply should not be writable, as it can only be read.
- if an error happen dbus_connection_send_with_reply_and_block()
will return NULL so we need check before use it
- all other send calls remove one reference of the message
Now also it is creating a error message, so the caller can know why it fail.

Summary: This adds a public facing API function to make dbus calls
which will block and wait for a reply. This is needed for a couple of

Summary: This just adds the function prototype into the eldbus private

Summary:
This fixes the breakage when Eldbus_Service_Interface_Desc added a
wrongfully methods2 field to a class that is allocated by the user.
This patch adds the respective eldbus_service_interface_register2 and
eldbus_service_interface_fallback_register2 for registration of
Eldbus_Service_Interface_Desc2 which is now versioned. So future the
functions can be backwards compatible and the struct be forward
compatible and leaves the Eldbus_Service_Interface_Desc and
eldbus_service_interface_register and
eldbus_service_interface_fallback_register intact as it was in EFL
1.10.
This fixes T1408

Summary:
Removed the void* data variable from Eldbus_Method and created another
struct that has the void* data and added an array of Eldbus_Method2 in
the descriptor for the Eldbus_Service_Interface_Desc and making the
appropriate modifications in the implementation to use both
descriptions.

Summary:
Applications can:
void method_callback(void* data, const Eldbus_Service_Interface* iface,
const Eldbus_Message* message);
struct { ... } data_struct;
Eldbus_Method methods[] =
{
"method1", ELDBUS_ARGS("b", "bool"), ELDBUS_ARGS("b", "bool"), ELDBUS_METHOD_FLAG_HAS_DATA
, (Eldbus_Method_Cb)&method_callback, &data_struct
};
And method_callback will be called with data parameter pointing to data_struct global object.
Also, Eldbus-cxx supports registering an interface passing a lambda or
function object as method. For example:
edb::service_interface iface = edb::service_interface_register
(c, path, interface
, es::method("SendStringAndBool"
, [expected_string, expected_bool] (std::string const& n, bool b
, bool* out)
{
std::cout << "Running SendStringAndBool" << std::endl;
ck_assert(n == expected_string);
ck_assert(b == expected_bool);
*out = b;
return n;
}
, es::ins<std::string, bool>("string", "bool")
, es::outs<std::string, bool>("string", "bool")
)
);
When a request for "SendStringAndBool" with the proper signature is
called, executes the lambda and replies with the return value and
its bool* out parameter value.

Being annoyed by different types of eina critical macros - CRI, CRIT,
CRITICAL -, I concluded to unify them to one. Discussed on IRC and
finally, CRI was chosen to meet the consistency with other macros -
ERR, WRN, INF, DBG - in terms of the number of characters.
If there is any missing bits, please let me know.

This happen because proxy was already freed and we try print some information
about the proxy in error message.
