* This commit solves the cellPngDec GetMemFromAddr(0x0) error when
loading PNGs from files.
* cellVideoOutGetResolution, cellRtc* syscalls rewritten to use the use
the mem*_t data types.
* Replaced int/uint with s32/u32 in some syscall arguments and structs.
* 41 new dummy modules created.
NOTE: I have detached the previous 4 dummy modules of my last commit
(1a85ccbbf4) from the project since they will consume space of the
executable, and compilation time and don't provide anything useful yet,
the same applies to this commit. The only reason to provide this dummy
modules is to avoid that developers have to spend too much time on
creating the template of the module before implementing functions. If
you want to implement a function of any of these modules, add the
corresponding file to the project first.
