[PULL 11/13] linux-user: Add support for selecting alsa timer using ioctl |

From: Filip Bozuta <address@hidden>
This patch implements functionality of following ioctl:
SNDRV_TIMER_IOCTL_SELECT - Selecting timer
Selects the timer which id is specified. The timer id is specified in the
following strcuture:
struct snd_timer_select {
struct snd_timer_id id; /* timer ID */
unsigned char reserved[32]; /* reserved */
};
A pointer to this structure should be passed as the third ioctl's argument.
Before calling the ioctl, the field "tid" should be initialized with the id
information for the timer which is to be selected. If there is no timer
device with the specified id, the error ENODEV ("No such device") is
returned.
Implementation notes:
Ioctl implemented in this patch has a pointer to a
'struct snd_timer_select' as its third argument.
That is the reason why a corresponding definition
was added in 'linux-user/syscall_types.h'. The rest
of the implementation was straightforward.
