fs: cast BFile support into generic file descriptors 
This paves the way for standard streams, USB streams, and some more.

kernel: tentative stack overflow panic, 14 kiB stack on G-III 
I saw a crash with the 12 kB stack. Added an error message to diagnose
further similar issues, and bumbed the stack to 14 kB. That's a lot of
space just for BFile but stability is queen... :x

hardware: expose filesystem type in the hardware info 
Filesystem type is detected with a trivial heuristic:
* fx-9860G: CASIOWIN, unless Fugue in the G-III series (OS >= 3.00)
* fx-CG 50: Always Fugue

kernel: increase stack size to 12 kB on SH4 fx-9860G 
BFile calls on the G-III series can overflow an 8 kB stack, overriding
the VBR which is located just before (!).

tmu: fix freeze when using sleep_us_spin() with interrupts on 
Because of timing the interrupt handler could run before the flag is
checked.

bfile: use non-smem syscalls for Fugue 
Not sure how the design is internally, but only these ones can find
files in subfolders.

dma: add support for standard DMA access to SPU memory 
* Mark SPU memory as sleep-blocking.
* Perform 4-byte accesses only in dma_memset() and dma_memcpy() (32-byte
  accesses freeze as one would expect).

This change does *NOT* implement support for SPU's integrated DMAC.

bopti: fix a VRAM overflow through the rightmost column 
The checks for VRAM access account for image columns intersecting the
longword before the start of a VRAM line, but not the longword after the
start of a VRAM line. This is now fixed.

cmake: add interface flags for OpenLibm and the libc 
Known limitation: OpenLibm can't be installed out of the compiler prefix
yet (because of that pesky openlibm/ prefix that it installs to but does
not use when including).
