This commit adds all the changes made to the 3GX plugin loader fork of Luma3DS. The most important features are:
- Add 3GX plugin loader support. New service added to rosalina: plg:ldr
- Add svcControlProcess, svcControlMemoryUnsafe and improve svcMapProcessMemoryEx (breaking change)
- Allow applications to override certain configurations depending on their needs:
- Disable core2 thread redirection
- Disable game patching for the next app
- Force New 3DS speedup
- Force next application in a specific memory mode
- Block the opening of the Rosalina menu
- Add GDB commands to list all process handles and catch all SVC (latter is for IDA Pro as gdb client supports it)
- Other changes necessary for plugins to work properly. Please check changed files in this PR for more details.
