* SearchFree adjustments
* Robust address validation
I've adjusted IsValidAddress to take in a size, and check whether the whole range is contained in vma map.
If no size is provided, the function reverts to the old form of address validation instead.
* Map around gaps
As is, this should work mostly.
Only remaining issue is adding logic to pass the "mapped regions" to the guest vma map (and make such logic cross-platform).
* Initialize vma_map using gaps
This should allow memory code to catch any issues from address space gaps, and prevent non-fixed mappings from jumping to a location that isn't actually available.
* Clang
* Fix compile
* Clang
* Fix compile again
* Set system_managed_base and system_managed_size based on
Many places in our code use system_managed_base as the minimum mappable address, ensure this fact remains the same on Windows to prevent potential bugs.
* Reduce address validation in SearchFree
Allows SearchFree to function when a certain Windows GPU driver goes and reserves the whole system managed area.
Since SearchFree is only called on flexible addresses, allowing this particular case, where addresses are in bounds, but there's not enough space to map, should be safe enough.
* Bump address space size further
To handle Madden NFL 16 (and any games like it)
* More thorough logging of available memory regions
Should help with spotting weirdness.
* Formatting fixes
* Clang
* Slight reduction of user space
Still large enough to handle EA's shenanigans, but small enough that Linux doesn't break.
* Assert on VirtualQuery failure
* Extra debugging information
* Further reduce user space
This will unfix most of EA's titles, but UFC will still work.
Older windows versions support the high addresses, but trying to actually use them causes significant performance issues.
* Extra debugging info
Just in case other testers still run into issues.
* Remove debug logging
* Revert user space increases
Technically this constant is still higher than before, but weird side effects of our old logic resulted in a max address somewhere around this in main.
* address_space: Support expanded virtual memory space on macOS.

* Move address space constants to address_space.cpp
This ensures that all code must use the calculated address space memory values instead of the constants, since the calculated values can differ based on the platform.
This does require slight modification to thread state and gnmdriver code, since both were already using these constants directly.
* Workaround Windows 10 limitations
If a Windows 10 device is detected, use a lower value for USER_MAX to prevent system-wide hangs in VirtualAlloc2 calls.
* Fix compile for Windows-Qt
* Move tessellation_factors_ring_addr initialization to sceGnmGetTheTessellationFactorRingBufferBaseAddress
* Set image base address on Windows
This seems to work fine on Windows 11, needs testing from Windows 10 due to the previously discussed bugs.
* Set Linux executable base to 0x700000000000
This allows Linux to map the full user space without any workarounds.

* Basic formatting changes
* Reduce USER_MAX on Linux
Seems like finding a reliable way to move shadPS4's position in memory is difficult, for now limit the user size so we aren't trying to overwrite ourselves.
* Move memory and address_space variables.

* Remove checks for module version_major and version_minor
Following this rule broke linking for some libraries, and introduced extra effort needed to get some homebrew running.
* Clang
* Fix rebase
* Disable libSceSsl HLE
Real hardware uses a title workaround to determine if base libSceSsl is needed. Currently, this title workaround applies to absolutely nothing.
* posix_pthread_attr_getschedparam
* Fixes for scePthreadGetAffinity and scePthreadSetAffinity
Looking at FreeBSD source, and our other pthread functions, we should be using our FindThread function to get the appropriate thread if thread != g_curthread.
* core: Split error codes into separate files
* Reduces build times and is cleaner
* core: Bring structs and enums to codebase style
* core: More style changes
* 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
