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

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

Leonid Vasiliev (5):
  error: Add a Lua backtrace to error
  error: Add the custom error type
  error: Increase the number of fields transmitted through IPROTO
  iproto: Add session settings for IPROTO
  iproto: Update error MsgPack encoding
