[Leonid Vasiliev]

https://github.com/tarantool/tarantool/issues/4398
https://github.com/tarantool/tarantool/tree/lvasiliev/gh-4398-expose-error-module-5

Changes from previous:
- traceback patch has been removed
- Vlad patches have been applied
- Update old tests and add new
- Make iproto errors reuse mp_error module

According to https://github.com/tarantool/tarantool/issues/4398
(and after some discussion) we would like box.error to have:
* Ability to create new error types
* Transparent marshalling through net.box

@Changelog
Added:
Posibility to create errors of a custom user type
Transparent marshalling error through net.box(gh-4398)

  error: add custom error type
  error: add session setting for error type marshaling
  error: update constructors of some errors
  error: add error MsgPack encoding
  error: fix iproto error stack overlapped by old error

Vladislav Shpilevoy (5):

  box: move Lua MP_EXT decoder from tuple.c
  error: export error_unref() function
  error: make iproto errors reuse mp_error module
  iproto: rename IPROTO_ERROR and IPROTO_ERROR_STACK
