fix mounting /app_home

[bibarub]

webMAN didn't mount /app_home correctly (it was mounting USRDIR to /app_home. i don't know the reason behind this, but it does not work at all), this commit fixes it

USRDIR-related code has been removed from both map_app_home and set_app_home, the multidisc logic from map_app_home has been commented out (it's completely broken), the conditions in set_app_home have been edited a bit

(i only tested it on HEN 3.3.0, not sure if it works on CFW)

@bibarub Thank you for your pull request. I have applied almost all your changes, except the removal of the multi-disc logic.

I added comments explaining how it works. Maybe you didn't get how the logic works. I tested it on CFW some years ago.
Basically it requires to mount the same ISO multiple times to mount PS3_GM02, PS3_GM03, etc.

If the code is broken as you mentioned in your comments, it needs to be fixed not removed 😃

sorry, didn't think about that at all xD. thank you for merging the code

by the way, change '18' to '11' at line 941 in include/mount/mount.h. the 7 extra bytes were used for "/USRDIR", which we don't touch anymore

also, you forgot to change the comment at line 921 in the same file

regarding the multi-disc code
don't multi-game discs still use PS3_GAME for the first game? i don't have any multi-game ISOs so i don't know how it works, just asking you to make sure

Yes. This DisgeaTriplePlayCollectionFilelist.txt is supposed to be the directory structure from the multi-game disc "Disgea Trilogy Collection" .

I obtained it from this post https://www.psx-place.com/threads/make-multidisc-ps3-game.41758/

Current code seems to cycle only from PS3_GM01 to PS3_GM99, ignoring PS3_GAME if they exist.

I think the line 947 should be changed to gm = 01; sprintf(mpath, "%s/PS3_GAME", path); to fix the issue but I don't have a multi-game ISO to test.

Anyway this only affect noBD consoles that require mount JB games through /app_home. /dev_bdvd show multi-game discs in separated disc icons.
