John Preston 8e89486fbc Error handling changed, 'auto' keyword used for MTP types.
All errors that lead to MTP request resending by default
error handler now can be handled differently. For example
inline bot requests are not being resent on 5XX error codes.
+ extensive use of auto keyword in MTP types handling.
