libretro: set up the FPU before the first frame
...
save_fpu() and restore_fpu() call the FPU emulation through function
pointers that fpu_reset() only sets up when the first m68k_go() resets
the CPU. A frontend may ask for the state size, or save or load a state,
before the first retro_run() - Kodi does when a game starts - and the
core crashed calling a null pointer.

libretro: open stdout and stderr as the streams
...
File_Open() opened "stdout" and "stderr" as files in the current
directory. Log_Init() opens both by default, so where that directory
isn't writable (Kodi on LibreELEC runs in /) logging failed to start,
Main_ErrorExit() set bQuitProgram and the core never ran a frame.
Return the standard streams for the special names as src/file.c does,
and don't close them in File_Close().

libretro: option to disable the virtual keyboard
...
A core option Virtual Keyboard (enabled by default) turns the on-screen
keyboard off altogether, for when a real keyboard is used; it replaces
the Disabled choice of Virtual Keyboard Button.

libretro: carry out RetroArch's reset on the CPU too
...
retro_reset() reset the devices and asked the CPU to reset, but the next
retro_run() set quit_program to 0 before m68k_run(), dropping the
request: only m68k_go() carries a reset out. The CPU went on with the
code from before on devices reset under it - the machine did not
restart, and the mouse no longer moved (the reset had also cleared the
interrupt that sends the IKBD's mouse packets).
retro_run() now enters m68k_go() when a reset is pending, as it already
does after a CPU setting changed. m68k_go() always clears the memory on
entry, so retro_reset() asks for a cold reset, which is what it gets.

Move filename related functions into a separate file

file.c is a mixture between filename handling functions and file access

but switch to different file access functions there. To make this possible,
split the filename handling functions into a separate file first.
