[Leonid Vasiliev]

https://github.com/tarantool/tarantool/issues/4398
https://github.com/tarantool/tarantool/tree/lvasiliev/gh-4398-expose-error-module-4

Changes from previous:
- traceback patch has been removed
- Vlad patches have been applied

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
* Lua backtrace

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

Leonid Vasiliev (5):
  error: add custom error type
  error: send custom type in IProto
  error: add session setting for error type marshaling
  error: update constructors of some errors
  error: add error MsgPack encoding

Vladislav Shpilevoy (1):
  session: add offset to SQL session settings array
