Added the syscalls for sys_read_dir(), and sys_rewind_dir().

sys_read_dir() now has a parameter for the maximum number of dirents that
are handled by the upper layer - which is currently 1.
Added a comment in fd.h to ease the location of the sys|user prototypes
of the corresponding functions in fd.c.
