Qemu_savevm_state_cleanup takes about 300ms in my ram migration tests
with a 8U24G vm(20G is really occupied), the main cost comes from
KVM_SET_USER_MEMORY_REGION ioctl when mem.memory_size = 0 in
kvm_set_user_memory_region. In kmod, the main cost is
kvm_zap_obsolete_pages, which traverses the active_mmu_pages list to
zap the unsync sptes.
It can be optimized by delaying memory_global_dirty_log_stop to the next
vm_start.
Changes v2->v3:
- NULL VMChangeStateHandler if it is deleted and protect the scenario
of nested invocations of memory_global_dirty_log_start/stop [Paolo]
Changes v1->v2:
- create a VMChangeStateHandler in memory.c to reduce the coupling [Paolo]

Clang static analyzer reports a memory leak. Actually, the allocated
memory escapes here:
record->attribute_list[record->attributes].pair = data;
but clang is correct that the memory might leak if len is zero. We
know it isn't; assert that it is the case.
The craziness doesn't end there. The memory is freed by
bt_l2cap_sdp_close_ch:
g_free(sdp->service_list[i].attribute_list->pair);
which actually should have been written like this:
g_free(sdp->service_list[i].attribute_list[0].pair);
The attribute_list is sorted with qsort; but indeed the first
entry of attribute_list should point to "data" even after the qsort,
because the first record has id SDP_ATTR_RECORD_HANDLE, whose
numeric value is zero.
But hang on. The qsort function is
static int sdp_attributeid_compare(
const struct sdp_service_attribute_s *a,
const struct sdp_service_attribute_s *b)
{
return (int) b->attribute_id - a->attribute_id;
}
but no one ever writes attribute_id. So it only works if qsort is
stable, and who knows what else is broken, but we can fix it by
setting attribute_id in the while loop.

Commit 04bf2526ce (exec: use
qemu_ram_ptr_length to access guest ram) start using qemu_ram_ptr_length
instead of qemu_map_ram_ptr, but when used with Xen, the behavior of
both function is different. They both call xen_map_cache, but one with
"lock", meaning the mapping of guest memory is never released
implicitly, and the second one without, which means, mapping can be
release later, when needed.
In the context of address_space_{read,write}_continue, the ptr to those
mapping should not be locked because it is used immediatly and never
used again.
The lock parameter make it explicit in which context qemu_ram_ptr_length
is called.

The deprecation of features in QEMU is totally adhoc currently,
with no way for the user to get a list of what is deprecated
in each release. This adds an appendix to the doc that records
when each deprecation was made and provides text explaining
what to use instead, if anything.
Since there has been no formal policy around removal of deprecated
features in the past, any deprecations prior to 2.10.0 are to be
treated as if they had been made at the 2.10.0 release. Thus the
earliest that existing deprecations will be deleted is the start
of the 2.12.0 cycle.

Code that checks dstate is unaware of SystemTap and LTTng UST dstate, so
the following trace event will not fire when solely enabled by SystemTap
or LTTng UST:
if (trace_event_get_state(TRACE_MY_EVENT)) {
str = g_strdup_printf("Expensive string to generate ...",
...);
trace_my_event(str);
g_free(str);
}
Add trace_event_get_state_backends() to fetch backend dstate. Those
backends that use QEMU dstate fetch it as part of
generate_h_backend_dstate().
Update existing trace_event_get_state() callers to use
trace_event_get_state_backends() instead.

QEMU keeps track of trace event enabled/disabled state and provides
monitor commands to inspect and modify the "dstate". SystemTap and
LTTng UST maintain independent enabled/disabled states for each trace
event, the other backends rely on QEMU dstate.
Introduce a new per-event macro that combines backend-specific dstate
like this:
#define TRACE_MY_EVENT_BACKEND_DSTATE() ( \
QEMU_MY_EVENT_ENABLED() || /* SystemTap */ \
tracepoint_enabled(qemu, my_event) /* LTTng UST */ || \
false)
This will be used to extend trace_event_get_state() in the next patch.
[Daniel Berrange pointed out that QEMU_MY_EVENT_ENABLED() must be true
by default, not false. This way events will fire even if the DTrace
implementation does not implement the SystemTap semaphores feature.
Ubuntu Precise uses lttng-ust-dev 2.0.2 which does not have
tracepoint_enabled(), so we need a compatibility wrapper to keep Travis
builds passing.
