Introduces USER_CREATABLE interface that must be implemented by
objects which are designed to created with -object CLI option or
object-add QMP command.
Interface provides an ability to do an optional second stage
initialization of the object created with -object/object-add
commands. By providing complete() callback, which is called
after the object properties were set.
It allows to:
* prevents misusing of -object/object-add by filtering out
objects that are not designed for it.
* generalize second stage backend initialization instead of
adding custom APIs to perform it
* early error detection of backend initialization at -object/
object-add time rather than through a proxy DEVICE object
that tries to use backend.

The trace-events "disable" keyword turns an event into a nop at
compile-time. This is important for high-frequency events that can
impact performance.
The "disable" keyword is currently broken in the simple trace backend.
This patch fixes the problem as follows:
Trace events are identified by their TraceEventID number. When events
are disabled there are two options for assigning TraceEventID numbers:
1. Skip disabled events and don't assign them a number.
2. Assign numbers for all events regardless of the disabled keyword.
The simple trace backend and its binary file format uses approach #1.
The tracetool infrastructure has been using approach #2 for a while.
The result is that the numbers used in simple trace files do not
correspond with TraceEventIDs. In trace/simple.c we assumed that they
are identical and therefore emitted bogus numbers.
This patch fixes the bug by using TraceEventID for trace_event_id()
while sticking to approach #1 for simple trace file numbers. This
preserves simple trace file format compatibility.

When running with trace backend e.g. "simple" the writer thread needs to be
implemented in the same process context as the trace points that will be
processed. Under libvirtd control, qemu gets first started in daemonized
mode to privide its capabilities. Creating the writer thread in the initial
process context then leads to a dead lock because the thread gets termined
together with the initial parent. (-daemonize)

The 9118 ethernet controller supports transmission of multi-buffer packets
with arbitrary byte alignment of the start and end bytes. All writes to
the packet fifo are 32 bits, so the controller discards bytes at the beginning
and end of each buffer based on the 'Data start offset' and 'Buffer size'
of the TX command 'A' format.
This patch uses the provided buffer length to limit the bytes transmitted.
Previously all the bytes of the last 32-bit word written to the TX fifo
were added to the internal transmit buffer structure resulting in more bytes
being transmitted than were submitted to the hardware in the command. This
resulted in extra bytes being inserted into the middle of multi-buffer
packets when the non-final buffers had non-32bit aligned ending addresses.

This patch changes the buffer size and offset internal state variables to be
updated on every "TX command A" write. Previously they were only updated for
the first segment, which resulted incorrect behavior for packets with more
than one segment. Each segment of the packet has its own CMD A command, with
its own buffer size and start offset.
Also update extraction of fields from the CMD A word to use extract32().

This enables support for device hotplug behind
pci bridges. Bridge devices themselves need
to be pre-configured on qemu command line.
Design:
- at machine init time, assign "bsel" property to bridges with
hotplug support
- dynamically (At ACPI table read) generate ACPI code to handle
hotplug events for each bridge with "bsel" property
Note: ACPI doesn't support adding or removing bridges by hotplug.
We detect and prevent removal of bridges by hotplug,
unless they were added by hotplug previously
(and so, are not described by ACPI).

Add ACPI based PCI hotplug library with bridge hotplug
support.
Design
- each bus gets assigned "bsel" property.
- ACPI code writes this number
to a new BNUM register, then uses existing
UP/DOWN registers to probe slot status;
to eject, write number to BNUM register,
then slot into existing EJ.
The interface is actually backwards-compatible with
existing PIIX4 ACPI (though not migration compatible).
This is split out from PIIX4 codebase so we can
reuse it for Q35 as well.
