shada: Translate errors and add error codes

Notes:
- E136 code greatly changed its meaning: now it is write error and not read
  error.
- E195 was removed because shada_read_everything will already do all the
  necessary error reporting.
- E886 can be reported by both :rshada and :wshada, but :rshada comes first and
  AFAIR it is the only error which is not E575 and can be reported by :rshada.
