2022-01-14hle: kernel: Fix service_threads access to be thread safe V2.bunnei
- PR #7699 attempted to fix CreateServiceThread and ReleaseServiceThread to be thread safe, but inadvertently introduced a possible dead-lock. - With this PR, we use a worker thread to manage the service thread list, allowing it only to be accessed by a single thread, and guaranteeing threads will not destroy themselves. - Fixes a rare crash in Pokemon Sword/Shield, I've now run this game for ~12 hours non-stop and am quite confident this is a good solution for this issue.

2022-01-13hle: kernel: Fix service_threads access to be thread safe.bunnei
- CreateServiceThread and ReleaseServiceThread can be accessed by different threads, uses a lock to make this thread safe. - Fixes a rare crash in Pokemon Sword/Shield that can occur when a new service thread is being created while an old one is being destroyed.

2021-12-30core: hle: kernel: Implement thread pinning.bunnei
- We largely had the mechanics in place for thread pinning, this change hooks these up. - Validated with tests https://github.com/Atmosphere-NX/Atmosphere/blob/master/tests/TestSvc/source/test_thread_pinning.cpp.
2021-12-28core: hle: kernel: Updated implementation of svcSetHeapSize.bunnei
- Updates our svcSetHeapSize with latest HOS, furthermore allowing heap size to properly be extended/shrunk. - Validated with tests https://github.com/Atmosphere-NX/Atmosphere/blob/master/tests/TestSvc/source/test_set_heap_size.cpp.

- Not seen in any games yet, but validated with kernel tests.
2021-12-23 core: hle: kernel: KThread: X18 should be a cryptographically random number.bunnei
- This was added with firmware 11.0.0 (https://switchbrew.org/wiki/11.0.0). - X18 is OR'd by kernel with 1, to make sure it is odd.

- Enforce tha the supplied handle is invalid, not valid. - This gets Witcher 3 booting.

Avoids a memory leak.
2021-12-17core: hle: Remove global HLE lock.bunnei
- This was added early on as a hack to protect against some concurrency issues. - It's not clear that this serves any purpose anymore, and if it does, individual components should be fixed rather than using a global recursive mutex.
