pcm/SampleFormat: remove wrong "malloc" attribute

*: check defined(_WIN32) instead of defined(WIN32)
...
Only _WIN32 is defined by the compiler, and WIN32 is not standardized
and may be missing.
Closes #169

storage, db, mixer, command: remove more bogus "pure" attributes
...
This commit is similar to 788e3b31e1#58 was most likely about StorageDirectoryReader::GetInfo() and
Storage::GetInfo(), which still had "pure" attributes.
Closes #58

*: add "noexcept" to many, many function prototypes
...
This eliminates some overhead, because the compiler doesn't need to
consider these functions throwing.

pcm/SampleFormat: workaround for GCC 4.9 "constexpr" bug

GCC 4.9 has incomplete C++14 support. Specifically, it doesn't allow
switch/case in "constexpr" functions.

pcm/PcmChannels: silence surround channels when converting from stereo
...
Previously, there was no special code to convert stereo to
multi-channel. The generic solution for this was to convert to mono,
and then copy the result to all channels. That's a pretty bad
solution, but at least something which always renders audio. MPD does
something, instead of failing.
Now that MPD has proper support for multi-channel (by defining the
channel order), we can do better than that. It is a (somewhat) common
case to play back stereo music on a DAC which can only do
multi-channel. The best approach here is to copy the stereo channels
to front-left and front-right, and apply the "silence" pattern to all
other channels.

The byte order of DSD_U32 was wrong from the start. The oldest bits

DSD_U32 packs four bytes instead of one large "sample", thus the
sample rate is one quarter of the input sample rate. This fixes a
rather critical DSD_U32 playback problem.
