The default for creating libraries is static but can be overridden
by setting BUILD_SHARED_LIBS variable. Setting it explicitly makes it
impossible to override.

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.

This applies when MA_NO_NEON or MA_NO_SSE2 is set.

Public issue https://github.com/mackron/miniaudio/issues/997

Fix leaked OggVorbis_File handle when input is not vorbis. Also implements ma_libvorbis_get_length_in_pcm_frames() for the common case of an ogg file with a single bitstream.

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.

This is untested.
