528a060709 Core: Memory code cleanup and further direct memory fixes (#3655)
* Remove mapped dmem type

Since physical addresses can be mapped multiple times, tracking mapped pages is not necessary.
This also allows me to significantly simplify the MapMemory physical address validation logic.

* Proper implementation for sceKernelMtypeprotect

I've rewritten SetDirectMemoryType to use virtual addresses instead of physical addresses, allowing it to be used in sceKernelMtypeprotect.

To accommodate this change, I've also moved address and size alignment out of MemoryManager::Protect

* Apply memory type in sceKernelMemoryPoolCommit

* Organization

Some potentially important missing mutexes, removed some unnecessary mutexes, moved some mutexes after early error returns, and updated copyright dates

* Iterator logic cleanup

Missing end check in ClampRangeSize, and adjusted VirtualQuery and DirectMemoryQuery.

* Clang

* Adjustments

* Properly account for behavior differences in MapDirectMemory2

Undid the changes to direct memory areas, added more robust logic for changing dma types, and fixed DirectMemoryQuery to return hardware-accurate direct memory information in cases where dmas split here, but not on real hardware.

I've also changed MapMemory's is_exec flag to a validate_dmem flag, used to handle alternate behavior in MapDirectMemory2. is_exec is now determined by the use of MemoryProt::CpuExec instead.

* Clang

* Add execute permissions to physical backing

Needed for executable mappings to work properly on Windows, fixes regression in RE2 with prior commit.

* Minor variable cleanup

* Update memory.h

* Prohibit direct memory mappings with exec protections

Did a quick hardware test to confirm, only seems to be prohibited for dmem mappings though.

* Update memory.cpp

f4531fd927 Core: Remove checks for symbol version_major and version_minor (#3540)
* 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.

fed064931a Core: Fix module load addresses (#2879)
* Fix module map addresses

Most modules are mapped starting at 0x800000000, with no gaps between mappings.

* Hardcode hardware accurate base address

Looking at our address space, all platforms will have this base address mapped, so there shouldn't be any problem in using it.

* Clang

* Swap module mapping to NoFlags, remove offset code

Since real hardware has no gap between module mappings, the Fixed flag is just an annoyance to work around, and has no impact on the actual mappings.
Swapping the module mappings to use flags NoFlags instead simplifies our code slightly.

* Fix module mapping names

On real hardware, the file extension is part of the mapping name. Easiest way to manage this is to swap the name to be `file.filename().string()` instead of `file.stem().string()`

* Fix patches

Completely missed this, whoops.

410313ca87 Implement sceKernelGetModuleInfo, sceKernelGetModuleInfoInternal, and sceKernelGetModuleList (#2850)
* Fix GetModule exception

Simple mistake

* Prevent OOB writes in add_segment

Due to mistakes in our linker logic, OpenOrbis' libSceFios2 causes OOB writes here.
While the ideal solution would be to fix the erroneous behavior, the best I'm capable of right now is just preventing the OOB writes.

* Implement sceKernelGetModuleInfo, sceKernelGetModuleInfoInternal, sceKernelGetModuleList

These are implemented based on hardware observations and a homebrew sample made by red_prig. I've yet to test what error cases can show up.

* Clang

* Accurate error returns

If there are more modules than provided space, then return kernel ENOMEM.
If either handles or out_count are null, return kernel EFAULT.

* Accurate error checks in ModuleInfo functions

* Clang

614a23b369 Cheats/Patches (#493)
* Cheats/Patches

Adds the possibility of applying cheats/patches according to the specific game serial+version

The logic for adding modifications has not yet been implemented!

Interface based on issues/372 https://github.com/shadps4-emu/shadPS4/issues/372

[X]Front-end
[]Back-end

Create a synchronized fork of the cheats/patches repository

* Clang Format

* separate files

The code has been separated into separate files as suggested by georgemoralis.
Added the Patch tab, which has not been implemented yet.
Added the 'applyCheat' area to apply the modification, not implemented yet...
And added LOG_INFO.

* reuse

* initial implementation of cheat functionality

* Update cheats_patches.cpp

sets all added buttons to the size of the largest button.
and fixes some aesthetic issues.

* move eboot_address to module.h

fixes the non-qt builds and makes more sense to be there anyway

* Patchs menu and fixes

adds the possibility to download Patches, it does not modify the memory yet.
and some other fixes

* MemoryPatcher namespace, activate cheats on start

* format

* initial patch implementation

* format

* format again...

* convertValueToHex

* Fixes

Choosing which cheat file to use.
And some other fixes

* fix bytes16, bytes32, bytes64 type patches

If a patch is any of these types we convert it from little endian to big endian

* format

* format again :(

* Implement pattern scanning for mask type patches

* add check to stop patches applying to wrong game

previously if you added a patch to a game, but closed the window and opened a different game it would still try to apply the patch, this is now fixed

* format

* Fix 'Hint' 0x400000 |  and Author

* Management |save checkbox | shadps4 repository

MENU - Cheats/Patches Management (implementing Patches)
save patches checkbox
add shadps4 repository

* Load saved patches, miscellaneous fixes

* Fix an issue with mask patches not being saved

* format + remove debug log

* multiple patches | TR translation for cheats/patches

* clang

* ENABLE_QT_GUI

* OK

* move memory_patcher to qt_gui

* clang

* add cheats hu_HU

* fix log

* Remove the item from the patchesListView if no patches were added (the game has patches, but not for the current version)
