Simplify and improve 'list' property

When a source/output/etc has a property of a 'list' type, there was no
way to get the names associated with its values.  That, and it only
supported lists of either text, or enums (0..[value] only).

Now, you can associate translated names with those values, and use
integer, float, or string values.  Put it all in to one function as well
to simplify its usage.

I plan on using this to help get enumerations from devices/etc for
certain types of sources.  For example, if I get the properties of an
audio source, I'd like to have a list of available devices with it as
well.
Fix non-VS compile issues

As usual, microsoft treats all enums as integers, rather than actually
even checking the enum type.  Worthless compiler.  Just complete
garbage.
Check for duplicate names (function parser)
Remove categories from properties

Categories added an unnecessary complexity to making properties, and
would very likely almost never be used in most cases, and were more of a
display feature.  The main issue is that it made property data more
complex to work with, and I just didn't feel comfortable with that.

Also, added a function to allow you to retrieve a porperty just by its
name.
Split output/input audio capture sources

 - Split input and output audio captures so that they're different
   sources.  This allows easier handling and enumeration of audio
   devices without having to do some sort of string processing.

   This way the user interface code can handle this a bit more easily,
   and so that it doesn't confuse users either.  This should be done for
   all audio capture sources for all operating systems.  You don't have
   to duplicate any code, you just need to create input/output wrapper
   functions to designate the audio as input or output before creation.

 - Make it detect soundflower and wavtap devices as mac "output" devices
   (even though they're actually input) for the mac output capture, and
   make it so that users can select a default output capture and
   automatically use soundflower or wavtap.

   I'm not entirely happy about having to do this, but because mac is
   designed this way, this is really the only way to handle it that
   makes it easier for users and UI code to deal with.

   Note that soundflower and wavtap are still also designated as input
   devices, so will still show up in input device enumeration.

 - Remove pragma messages because they were kind polluting the other
   compiler messages and just getting in the way.  In the future we can
   just do a grep for TODO to find them.

 - Redo list property again, this time using a safer internal array,
   rather than requiring sketchy array inputs.  Having functions handle
   everything behind the scenes is much safer.

 - Remove the reference counter debug log code, as it was included
   unintentionally in a commit.
CoreAudio: Fail if no output device found

Also, don't have it repeat trying to reconnect if no devices are found
CoreAudio: Don't reconnect if no output devices

Somehow this code didn't get included with the last commit.
Add WASAPI audio capture

 - Add WASAPI audio capture for windows, input and output

 - Check for null pointer in os_dlopen

 - Add exception-safe 'WinHandle' and 'CoTaskMemPtr' helper classes that
   will automatically call CloseHandle on handles and call CoTaskMemFree
   on certain types of memory returned from windows functions

 - Changed the wide <-> MBS/UTF8 conversion functions so that you use
   buffers (like these functions are *supposed* to behave), and changed
   the ones that allocate to a different naming scheme to be safe
CoreAudio: Separate enumeration code

The enumeration code being up at the top was making things quite messy,
so I split that code out to a separate set of files.
WASAPI: Check the HRESULT values with FAILED

I can't believe I did !res there.  Well I suppose I can believe it, but
still.
