synth syscalls patch

Just a little patch I wrote when I needed to use shared memory from 
within the synth target.

2009-09-30  Simon Kallweit  <simon.kallweit@intefo.ch>

         * include/hal_io.h: added resource get request flags, using
         struct cyg_hal_sys_new_stat for cyg_hal_sys_newstat().
         * src/synth_syscalls.c: using cyg_hal_sys_newstat() instead
         of cyg_hal_sys_oldstat() in cyg_hal_sys_mmap().
