[openal] OpenAL Soft 1.23.1 released!

[Chris Robinson]

OpenAL Soft 1.23.1 has been released:

https://openal-soft.org/

Not as much in the way of any critical fixes this time around, but it 
does fix some compilation issues with older GCC versions, with newer 
Oboe on Android, and when building as a submodule.

Some new features have also been added, which have either been waiting 
for a while or were simple additions on what was already there. These 
include the extensions AL_SOFT_UHJ_ex, AL_SOFT_buffer_length_query, 
AL_SOFT_source_start_delay, and AL_EXT_STATIC_BUFFER[1], along with 
improved EAX API compatibility and a new compatibility option to restore 
the AL_SOFT_buffer_sub_data extension for apps that need it (Arma Cold 
War Assault being one such instance).

The homepage and the ChangeLog from the source package contain a more 
comprehensive list of changes.

Assuming no severe or significant issues arise, work will move on to 
1.24. As mentioned in earlier messages, 1.24 will be switching to C++17, 
which will likely require GCC 7 or newer, Clang 4 or newer, and VS 2017 
or newer.

Thanks for your continued interest and support! Great things are planned 
and coming in the future, stay tuned.
