COMBOOT API: Add calls for directory functions; Implement for FAT
COMBOOT API: Add calls for directory functions; Implement most only
for FAT (SYSLINUX).
Uses INT 22h AX= 001Fh, 0020h, 0021h and 0022h to prepare for the
COM32 C functions getcwd(), opendir(), readdir(), and closedir(),
respectively. INT22h, AX=001Fh will return a valid value for all
variants. INT22h, AX= 0020h, 0021h, and 0022h are only implemented
for SYSLINUX while other variants will call comapi_err for these 3.
