A side effect is the git submodules are not cloned

Clone and build can be forced with --enable-fdt and
--enable-slirp.

linux-user: Use `qemu_log' for non-strace logging
Since most calls to `gemu_log` are actually logging unimplemented features,
this change replaces most non-strace calls to `gemu_log` with calls to
`qemu_log_mask(LOG_UNIMP, ...)`. This allows the user to easily log to
a file, and to mask out these log messages if they desire.
Note: This change is slightly backwards incompatible, since now these
"unimplemented" log messages will not be logged by default.

Log Message:

linux-user: Use `qemu_log' for strace
This change switches linux-user strace logging to use the newer `qemu_log`
logging subsystem rather than the older `gemu_log` (notice the "g")
logger. `qemu_log` has several advantages, namely that it allows logging
to a file, and provides a more unified interface for configuration
of logging (via the QEMU_LOG environment variable or options).
This change introduces a new log mask: `LOG_STRACE` which is used for
logging of user-mode strace messages.

linux-user: Add support for getting alsa timer version and id
This patch implements functionalities of following ioctls:
SNDRV_TIMER_IOCTL_PVERSION - Getting the sound timer version
Read the sound timer version. The third ioctl's argument is
a pointer to an int in which the specified timers version
is returned.
SNDRV_TIMER_IOCTL_NEXT_DEVICE - Getting id information about next timer
Read id information about the next timer device from the sound timer
device list. The id infomration is returned in the following structure:
struct snd_timer_id {
int dev_class; /* timer device class number */
int dev_sclass; /* slave device class number (unused) */
int card; /* card number */
int device; /* device number */
int subdevice; /* sub-device number */
};
The devices in the sound timer device list are arranged by the fields
of this structure respectively (first by dev_class number, then by
card number, ...). A pointer to this structure should be passed as
the third ioctl's argument. Before calling the ioctl, the parameters
of this structure should be initialized in relation to the next timer
device which information is to be obtained. For example, if a wanted
timer device has the device class number equal to or bigger then 2,
the field dev_class should be initialized to 2. After the ioctl call,
the structure fields are filled with values from the next device in
the sound timer device list. If there is no next device in the list,
the structure is filled with "zero" id values (in that case all
fields are filled with value -1).
Implementation notes:
The ioctl 'SNDRV_TIMER_IOCTL_NEXT_DEVICE' has a pointer to a
'struct snd_timer_id' as its third argument. That is the reason why
corresponding definition is added in 'linux-user/syscall_types.h'.
Since all elements of this structure are of type 'int', the rest of
the implementation was straightforward.
The line '#include <linux/rtc.h>' was added to recognize
preprocessor definitions for these ioctls. This needs to be
done only once in this series of commits. Also, the content
of this file (with respect to ioctl definitions) remained
unchanged for a long time, therefore there is no need to
worry about supporting older Linux kernel version.

linux-user: Add support for getting/setting specified alsa timer parameters
using ioctls
This patch implements functionalities of following ioctls:
SNDRV_TIMER_IOCTL_GINFO - Getting information about specified timer
Read information about the specified timer. The information about the
timer is returned in the following structure:
struct snd_timer_ginfo {
struct snd_timer_id tid; /* requested timer ID */
unsigned int flags; /* timer flags - SNDRV_TIMER_FLG_* */
int card; /* card number */
unsigned char id[64]; /* timer identification */
unsigned char name[80]; /* timer name */
unsigned long reserved0; /* reserved for future use */
unsigned long resolution; /* average period resolution in ns */
unsigned long resolution_min; /* minimal period resolution in ns */
unsigned long resolution_max; /* maximal period resolution in ns */
unsigned int clients; /* active timer clients */
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 information is to be obtained. After the
ioctl call, the rest of the structure fields are filled with values from
the timer device with the specified id. If there is no device with the
specified id, the error ENODEV ("No such device") is returned.
SNDRV_TIMER_IOCTL_GPARAMS - Setting precise period duration
Sets timer precise period duration numerator and denominator in seconds. The
period duration is set in the following structure:
struct snd_timer_gparams {
struct snd_timer_id tid; /* requested timer ID */
unsigned long period_num; /* period duration - numerator */
unsigned long period_den; /* period duration - denominator */
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 period duration is to be set. Also, the
fileds "period_num" and "period_den" should be filled with the period
duration numerator and denominator values that are to be set respectively.
If there is no device with the specified id, the error ENODEV ("No such
device") is returned.
SNDRV_TIMER_IOCTL_GSTATUS - Getting current period resolution
Read timer current period resolution in nanoseconds and period resolution
numerator and denominator in seconds. The period resolution information is
returned in the following structure:
struct snd_timer_gstatus {
struct snd_timer_id tid; /* requested timer ID */
unsigned long resolution; /* current period resolution in ns */
unsigned long resolution_num; /* period resolution - numerator */
unsigned long resolution_den; /* period resolution - denominator */
unsigned char reserved[32]; /* reserved for future use */
};
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 period resolution is to be obtained. After
the ioctl call, the rest of the structure fields are filled with values
from the timer device with the specified id. If there is no device with the
specified id, the error ENODEV ("No such device") is returned.
Implementation notes:
All ioctls in this patch have pointer to some kind of a structure as their
third argument. That is the reason why corresponding definitions were added
in 'linux-user/syscall_types.h'. All of these strcutures have some fields
that are of type 'unsigned long'. That is the reason why separate target
structures were defined in 'linux-user/syscall_defs.h'. Also, all of the
structures have a field with type 'struct snd_timer_id' which is the reason
why a separate target structure 'struct target_snd_timer_id' was also
defined. The rest of the implementation was straightforward.

Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which information is to be obtained. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.
SNDRV_TIMER_IOCTL_PARAMS - Setting parameters for selected timer
Sets parameters for the selected timer. The paramaters are set in the
following structure:
struct snd_timer_params {
unsigned int flags; /* flags - SNDRV_TIMER_PSFLG_* */
unsigned int ticks; /* requested resolution in ticks */
unsigned int queue_size; /* total size of queue (32-1024) */
unsigned int reserved0; /* reserved, was: failure locations */
unsigned int filter; /* event filter */
unsigned char reserved[60]; /* reserved */
};
A pointer to this structure should be passed as the third ioctl's argument.
Before calling this ioctl, the ioctl "SNDRV_TIMER_IOCTL_SELECT" should be
called first to select the timer which parameters are to be set. If no
timer is selected, the error EBADFD ("File descriptor in bad shape") is
returned.
SNDRV_TIMER_IOCTL_STATUS - Getting status of selected timer
Read status of the selected timer. The status of the timer is returned in
the following structure:
struct snd_timer_status {
struct timespec tstamp; /* Timestamp - last update */
unsigned int resolution; /* current period resolution in ns */
unsigned int lost; /* counter of master tick lost */
unsigned int overrun; /* count of read queue overruns */
unsigned int queue; /* used queue size */
unsigned char reserved[64]; /* reserved */

Implementation notes:
All ioctls in this patch have pointer to some kind of a structure
as their third argument. That is the reason why corresponding
definitions were added in 'linux-user/syscall_types.h'. Structure
'snd_timer_status' has field of type 'struct timespec' which is why
a corresponding definition of that structure was also added in
'linux-user/syscall_types.h'. All of these strucutures have some
fields that are of type 'unsigned long'. That is the reason why
separate target structures were defined in 'linux-user/syscall_defs.h'.
Structure 'struct timespec' already had a separate target definition
so that definition was used to define a target structure for
'snd_timer_status'. The rest of the implementation was straightforward.
