Emulate memory behavior of libSceGnmDriver initialization (#2807)
* Emulate memory behavior of libSceGnmDriver _DT_INIT

Due to the unique way some games check for sceKernelAllocateDirectMemory failures, emulating this properly is necessary.

* Clang

* Fix address input for direct memory call

* Fix bug with DirectQueryAvailable

Missed this in my prior PR.

* DirectQueryAvailable fix

Fixes error cases to be more hardware accurate.

* AllocateDirectMemory fixes

search_start and search_end were ignored in certain cases, this fixes that issue.
I've also basically rewritten the function in the process, since the lack of documentation made it difficult to make the proper adjustments.

* DirectQueryAvailable fixes

remaining_size was calculated incorrectly in cases where a free dmem_area had a base earlier than search_start, or an end after search_end.

* Reduce sceKernelGetDirectMemorySize log severity

By this point, we've confirmed that sceKernelGetDirectMemorySize is hardware-accurate. There's no reason to clog logs with this function, which games usually call before every sceKernelAllocateDirectMemory call.

* Clang

* Fix phys_addr_out

phys_addr_out should be equal to search_start in cases where search_start is greater than the dmem_area base.

* Dividing by zero is fun

Need to check for alignment when aligning things.

* Update memory.cpp

* Clang

sceKernelReleaseDirectMemory fix (#2623)
* Fix error return on sceKernelMunmap

FreeBSD docs state that len <= 0 is a EINVAL return.

* Early return on ReleaseDirectMemory with len = 0

Calls to these two functions with len = 0 cause an assert in CarveDmemArea. Since there's no memory to release, an early return should be safe here.

* Remove check for negative length in munmap

Improved error handling in sceKernelAllocateDirectMemory (#2037)
* Handle errors in sceKernelAllocateDirectMemory

* Improve accuracy of error cases

Some of our existing cases are normally EAGAIN returns.

* Improve logging on errors

* Clang

* TEMPORARY HACK FOR NBA TESTS

This will be removed before this PR is marked as ready, and is only here to make sure the other NBA games (and perhaps DOA3) work if some missing init behavior is handled.

* Revert "TEMPORARY HACK FOR NBA TESTS"

This reverts commit a0e27b0229.

* Change error message

7e525a59e4 Kernel Fixes (#1605)
* scePthreadSetprio Changes

FindThread uses posix error codes, so the function export should apply the ORBIS wrapper to convert these. Since it uses posix codes, I've also renamed the function to align with other posix functions. Lastly, this fixes a compile warning about ret sometimes not getting initialized.

* Implement posix_munmap

Used by Hatsune Miku Project Diva X during intros. May help with stability on Linux, probably won't change anything on Windows.

* Exports

Some missing function exports I've seen in my tests.
sceKernelAvailableFlexibleMemorySize export is used in Final Fantasy XV Episode Duscae
posix_pthread_setprio and posix_pthread_getschedparam are used by Spider-Man Miles Morales
scePthreadKeyDelete is used in UE4 games.

I've also added in a typo fix related to my previous PR.

* libScePosix export for posix_pthread_attr_setguardsize

Used in Hatsune Miku Project Diva X v1.02
