This disables the WASAPI, DirectSound and WinMM backends which means
you will not get any actual audio output working. An Xbox backend will
need to come later. The main purpose of this commit is to get the main
library compiling.
The main complication arises from the fact that both _WIN32 and
_MSC_VER are defined which makes miniaudio think it's using a normal
desktop Windows build. In practice it mostly works, but there's a few
things needing to be changed specifically for NXDK:
- `fopen_s()` is not a thing with NXDK. It always uses `fopen()`.
- There is no `_wfopen()`, nor `wcsrtombs()`, so attempting to open
a file from a wide character string will fail.
- There is also no `CreateFileW()`, so this code path will also
result in an error if you attempt to open a file from a wide
character path.
- `CoInitialize()` is not a thing with NXDK and has therefore been
excluded from the build.
- `GetFileInformationByHandle()` does not exist, and neither does
`struct stat` or `stat()`. Since the only file information miniaudio
attempts to retrieve is the file size, I've implemented a fall back
which uses the seek/tell/seek pattern when info retrieval is
unavailable.
- A fall back has been implemented for comparing wide character path
extensions which performs a case-sensitive compare instead. This
means that if you are using wide character paths, miniaudio will not
detect an extension like "wav" and "WAV" as the same thing. This
might be made more robust later if there is enough demand.

In ma_resource_manager_data_buffer_node_acquire_critical_section, a job which releases already acquired fences is either processed or posted based on MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_WAIT_INIT. However on job post or process failure, the fences were being unconditionally released.
This commit moves the fence releases in acquire_critical_section down into a nested branch which only executes if MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_WAIT_INIT is not set, causing the fence release to take place only if the job failed to post while relying on the job itself to release the fences if it processes rather than causing a duplicate ma_fence_release and thus an eventual assertion failure.
All Miniaudio static libraries now install their headers such that they can
still use relative paths, but external code can #include "miniaudio/miniaudio.h"
Also adds a CMake macro to simplify adding static libraries
My understanding is that "pause" was introduced with the Pentium 4 and
assembles to opcode F390 which is the same as "rep; nop". I believe this
should be backwards compatible.
Using "pause" here introduces an compilation error when targeting
architectures older than Pentium 4.
