Fix win trybot errors due to r4729.

The addition of logging.h in r4729 was causing the win trybot to fail
with "#pragma deprecated" errors in standard library headers. This
turned out to be due to including strsafe.h (via audio_device_config.h)
before sstream (via logging.h).

strsafe.h was only being included for the unused DEBUG_PRINT macro. I
removed all references to it.

This incidentally removes a bunch of other unneeded headers discovered
while trying to track the problem down.

This didn't show up in the commitbots; my guess is that the trybots are
using the VC10 toolchain and the commitbots the VC11 toolchain.
