XMRig 89cf1424a4
v6.9.0
v6.8.3

Added `pause-on-active` option

Windows only for now. When set to true, pauses mining when user touches mouse or keyboard.

Allow result submission to origin daemon with self-select

With `self-select` mode enabled, the `submit-to-origin` config option
will let the `SelfSelectClient` submit the solution to both
the daemon where it got the template from as well as to
the connected pool, for miners that want to do pool minining
with Monero and solo mining with an altcoin (merged mining variant).

Thank you and special credit to @StriderDM (https://github.com/StriderDM)!

Code and copyright cleanup.

Fixed macOS build.

v6.9.0

Fixed crash when GPU mining cn-heavy on Zen3 system

Simplified code, fixed broken pause.

Added idle time detection for macOS.
