IMPALA-2070: include the database comment when showing databases

Browse Source 
As part of change, refactor catalog and frontend functions to return
TDatabase/Db objects instead of just the string names of databases -
this required a lot of method/variable renamings.

Add test for creating database with comment. Modify existing tests
that assumed only a single column in SHOW DATABASES results.
