Andrey Lushnikov 75a8d7b0c3 [doclint] Prepare doclint for more checks
This patch refactors doclint so that more checks and more generators
could be added.

This patch:
- Introduces 'Source' class, which holds file content in-memory and
  allows it to be updated.
- Introduces 'Message' class - which is a pair of a text and a type.
  Messages could have either 'error' type or 'warning' type.
