alsa: more tapdancing to enumerate physical hardware devices.
Apparently some systems see "hw:", some see "default:" and some see
"sysdefault:" (and maybe others!). My workstation sees both "hw:" and
"sysdefault:" ...
Try to find a prefix we like and prioritize the prefixes we (think) we want
most. If everything else fails, if there's a "default" (not a prefix) device
name, list that by itself so the user gets _something_ here.
If we can't find a prefix we like _and_ there's no "default" device, report
no hardware found at all.

ALSA_snd_pcm_drop() can hang on some systems (Steam Link) so don't use that when shutting down the ALSA audio driver.

fix deadlock on close device
James Zipperer
snd_pcm_drain doesn't always drain when you unplug a usb device. Use snd_pcm_drop instead

audio: Clean up some CloseDevice() interface details.
- It's now always called if device->hidden isn't NULL, even if OpenDevice()
failed halfway through. This lets implementation code not have to clean up
itself on every possible failure point; just return an error and SDL will
handle it for you.
- Implementations can assume this->hidden != NULL and not check for it.
- implementations don't have to set this->hidden = NULL when done, because
the caller is always about to free(this).
- Don't reset other fields that are in a block of memory about to be free()'d.
- Implementations all now free things like internal mix buffers last, after
closing devices and such, to guarantee they definitely aren't in use anymore
at the point of deallocation.

audio: Removed internal SDL_audiomem.h and macros.
I think this was important for SDL 1.2 because some targets needed
special device memory for DMA buffers or locked memory buffers for use in
hardware interrupts or something, but since it just defines to SDL_malloc
and SDL_free now, I took it out for clarity's sake.

Shouldn't this be something ALSA handles for us with channel maps, so we can
just delete this code?

alsa: Implemented basic device detection.
This is kind of nasty, because ALSA reports dozens of "devices" that aren't
really things you'd ever want, or things that should be listed this way, but
the default path still works as before, and it at least allows these devices
to be available to apps.
This does not handle hotplugging yet. You get a device list at init time
and that's it.

Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
