[DBAL-1058] Fix database and namespace introspection for SQL Server

[deeky666]

It looks like some SQL Server versions / setups need system tables to be queried lowercased otherwise causing errors.

Looks sane to me. Did you have a chance to test this on your setup, @deeky666?

[deeky666]

@Ocramius yes I tested this and it works. But it worked before for me, too so I have no clue why some people get an error there. Either way, this patch does no harm and system tables are documented lowercase in the SQL Server docs so this should be fine.

Waiting for travis and then pressing zeh button

[deeky666]

@Ocramius thanks!

[Ocramius]

Also to check: merge back to 2.4

[Ocramius]

New test fails, sadly :-(

[stof]

It should also be backported to 2.5, not only to 2.4

[deeky666]

@stof I have that on my list.
@Ocramius will have a look later

[deeky666]

@Ocramius failing tests fixed now :)

[Ocramius]

Looking good. Will merge today.

[Ocramius]

Merged, thanks!

This won't be backported to 2.4.x due to conflicts - see http://www.doctrine-project.org/jira/browse/DBAL-1061
