Fix misc 21 (#1573)

* Make `sNew` in (unused) `code_800FC620.c` a string

It is passed as a filename to `__osMallocDebug` so should be a nul-terminated string, not a char[3] missing an explicit \0

* Fix gcc warning in `JpegDecoder_ParseNextSymbol` about SLL on negative value

-1U is an unsigned value, aka 0xFFFFFFFF
I keep -1 because it seems that's what a jpeg standard has too

* Small cleanup

* Fix few mistakes (thanks gcc warnings)

* Add `@bug` in file select settings draw code, using the wrong array

* format

* format main

* rename arg for a happy formatter

* Move important function call out of a printf
