afeecec2e8 Add rate limiting of RTC_CHANGE, BALLOON_CHANGE & WATCHDOG events
Allow certain event types to be rate limited to avoid flooding
monitor clients. The monitor_protocol_event() method is changed
such that instead of immediately emitting the event to Monitor
instances, it will call a new monitor_protocol_event_queue()
method.

This will check to see if the rate limit for the event has been
exceeded, and if so schedule a timer to wakeup at the end of the
rate limit period. If further events arrive before the timer fires,
the previously queued event will be discarded in favour of the new
event. The event will eventually be emitted when the timer fires.

This logic is applied to RTC_CHANGE, BALLOON_CHANGE & WATCHDOG
events, since the data associated with these events is stateless

 * monitor.c: Add support for rate limiting
 * monitor.h: Define monitor_global_init for one-time setup tasks
 * vl.c: Invoke monitor_global_init
 * trace-events: Add hooks for monitor event tracing

96dd9aac37 usb-host: rewrite usb_linux_update_endp_table
This patch carries a complete rewrite of the usb descriptor parser.
Changes / improvements:

 * We are using the USBDescriptor struct instead of hard-coded offsets
   now to access descriptor data.
 * (debug) printfs are all gone, tracepoints have been added instead.
 * We don't try (and fail) to skip over unneeded descriptors.  We parse
   them all one by one.  We keep track of which configuration, interface
   and altsetting we are looking at and use this information to figure
   which desciptors are in use and which we can ignore.
 * On parse errors we clear all endpoint information, which will
   disallow any communication with the device, except control endpoint
   messages.  This makes sure we don't end up with a silly device state
   where half of the endpoints got enabled and the other half was left
   disabled.
 * Some sanity checks have been added.

The new parser is more robust and also leaves complete device
information in the trace log if you enable the ush_host_parse_*
tracepoints.

250196f19c qcow2: Reduce number of I/O requests
If the first part of a write request is allocated, but the second isn't
and it can be allocated so that the resulting area is contiguous, handle
it at once. This is a common case for sequential writes.

After this patch, alloc_cluster_offset() only checks if the clusters are
already allocated or how many new clusters can be allocated contigouosly.
The actual cluster allocation is split off into a new function
do_alloc_cluster_offset().

6e4f59bd0d qed: replace is_write with flags field
Per-request attributes like read/write are currently implemented as bool
fields in the QEDAIOCB struct.  This becomes unwiedly as the number of
attributes grows.  For example, the qed_aio_setup() function would have
to take multiple bool arguments and at call sites it would be hard to
distinguish the meaning of each bool.

Instead use a flags field with bitmask constants.  This will be used
when zero write support is added.

f08f2ddae0 block: add .bdrv_co_write_zeroes() interface
The ability to zero regions of an image file is a useful primitive for
higher-level features such as image streaming or zero write detection.

Image formats may support an optimized metadata representation instead
of writing zeroes into the image file.  This allows zero writes to be
potentially faster than regular write operations and also preserve
sparseness of the image file.

The .bdrv_co_write_zeroes() interface should be implemented by block
drivers that wish to provide efficient zeroing.

Note that this operation is different from the discard operation, which
may leave the contents of the region indeterminate.  That means
discarded blocks are not guaranteed to contain zeroes and may contain
junk data instead.
