[PATCH v2 0/1] MR9262: Revert setting macOS QoS class in main thread.

[Marc-Aurel Zent (＠mzent)]

Server will overwrite this anyways (with also a boosted main thread priority/QoS class).

[PATCH v2 1/1] ntdll: Do not set main thread QoS class on macOS.

[Marc-Aurel Zent]

From: Marc-Aurel Zent <mzent(a)codeweavers.com>

Server already does so for us. This reverts the following two commits:

Revert "ntdll: Fix runtime availability check for pthread_attr_set_qos_class_np."

This reverts commit e605bc17a5657814a8f9a99e2a94d3222e03ba9d.

Revert "ntdll: Set the QoS class of the main Wine thread on macOS."

This reverts commit ed666db8d8d6afd740a266584a38e08622474821.
