Make alcSuspendContext and alcProcessContext batch updates
This behavior better matches Creative's hardware drivers and Rapture3D's OpenAL
driver. A compatibility environment variable is provided to restore the old
no-op behavior for any app that behaves badly from this change (set
__ALSOFT_SUSPEND_CONTEXT to "ignore").
If too many apps have a problem with this, the default behavior may need to be
changed to ignore, with the env var providing an option to defer/batch instead.
