CLEANUP: Nothing for non-Android here? ;)

Should this be folded into CommonMediaMimeTypes?

[servolk, 2015/05/06 01:13:39]

Yep, but it was like that in net/base/mime_util_unittest.cc and initially I just
moved some code with minimal changes as David suggested. I'll move this into
CommonMediaMimeTypes.

CLEANUP: It seems this is no longer needed, as we now require AT LEAST SDK
version 15 (aka ICS), AFAICT. I think we require version 16 (JB).

I would not recommend it for this CL, but something to do immediately after.

This would also let you remove the buildinfo include.

[servolk, 2015/05/06 01:13:39]

Ok, will do after this CL

[servolk, 2015/05/06 17:03:56]

Done as a separate CL:
