Patches: Virtual move/remove/create game files patches

[elad335]

Two new patch types, "move_file" and "hide_file":

"hide_file":
Specify the PS3 path of the file to mark as non-existant in offset field, the value field is unused. This can be used to "remove" cutscenes for example without needing to make any modification to game files. When specifying an already non-existant file this will prevent its creation further on. (ENOENT error code)

"move_file":
Specify the PS3 path of the file to "move" in offset field, and the destination path in value field. The original PS3 path does not have to exist for this operation to work. This can be used to install configurable mods and texture packs without modifying the original game files.

Do note that this can also be used on directories and PS3 partitions.
You do not have to specify "/dev_" at the start of path.

Examples:

• [ hide_file, /dev_hdd0/game/SERIAL/USRDIR/Video.mp4, "" ] # Mark the video as non-existant
• [ hide_file, hdd0/game/SERIAL/USRDIR/Video.mp4, "" ] # Same
• [ move_file, /dev_hdd0/game/SERIAL/USRDIR/Textures.tex, /dev_usbd/SERIAL/Textures.tex ] # Replace 'Textures.tex' with another file at /dev_usbd

I wanted to test this on a game, but I have been unable to get RPCS3's patch system to recognize it:

• [ move_file, hdd0/game/NPUA80908/USRDIR/built/game/scripts/arenas/pest_control.lc, usb000/pest_control.lc ]

Which spits out the error:
E PAT: Skipping patch data entry: [ move_file, 0x00000000, usb000/pest_control.lc ] (key: PPU-fadb0af6fb7bd0113e88fb9af3eb78fe3be05d08, location: line 68, column 8) yaml-cpp: error at line 69, column 92: bad conversion
Is this properly implemented with the patch manager? Because it seems like the offset doesn't want to take the string I've provided and instead replaces it with "0x00000000".

I wonder, does this VFS patching include support for files that are located within container files(like PSARC commonly), or is it only loose files that your own file browser can see?
