Paolo Bonzini 471f7e30a4 libcacard: improve documentation
Using the file-backed smartcard backend is black magic, but it can
be useful if your only smartcard bricks itself if it is accessed
the wrong way too many times.

Complete the documentation to include the art of creating certificates
and using them with QEMU, based on Ray Strode's useful tutorial at
https://blogs.gnome.org/halfline/2013/09/08/another-smartcard-post/
but with ccid-card-emulated or vscclient instead of SPICE.

Lluís Vilanova 5b808275f3 trace: Multi-backend tracing
Adds support to compile QEMU with multiple tracing backends at the same time.

For example, you can compile QEMU with:

  $ ./configure --enable-trace-backends=ftrace,dtrace

Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.

This patch allows having both available without recompiling QEMU.

Ján Tomko 38dbd48b24 virtio-balloon: return empty data when no stats are available
If the guest hasn't updated the stats yet, instead of returning
an error, return '-1' for the stats and '0' as 'last-update'.

This lets applications ignore this without parsing the error message.

Related libvirt patch and discussion:
https://www.redhat.com/archives/libvir-list/2014-May/msg00460.html

Tested against current upstream libvirt - stat reporting works and
it no longer logs errors when the stats are queried on domain startup.
(Note: libvirt doesn't use the last-update field for anything yet)

Benoît Canet 24fd848950 qapi: skip redundant includes
The purpose of this change is to help create a json file containing
common definitions; each bit of generated C code must be emitted
only one time.

A second history global to all QAPISchema instances has been added
to detect when a file is included more than one time and skip these
includes.
It does not act as a stack and the changes made to it by the
__init__ function are propagated back to the caller so it's really
a global state.

Markus Armbruster 297a3646c2 qapi: Replace uncommon use of the error API by the common one
We commonly use the error API like this:

    err = NULL;
    foo(..., &err);
    if (err) {
        goto out;
    }
    bar(..., &err);

Every error source is checked separately.  The second function is only
called when the first one succeeds.  Both functions are free to pass
their argument to error_set().  Because error_set() asserts no error
has been set, this effectively means they must not be called with an
error set.

The qapi-generated code uses the error API differently:

    // *errp was initialized to NULL somewhere up the call chain
    frob(..., errp);
    gnat(..., errp);

Errors accumulate in *errp: first error wins, subsequent errors get
dropped.  To make this work, the second function does nothing when
called with an error set.  Requires non-null errp, or else the second
function can't see the first one fail.

This usage has also bled into visitor tests, and two device model
object property getters rtc_get_date() and balloon_stats_get_all().

With the "accumulate" technique, you need fewer error checks in
callers, and buy that with an error check in every callee.  Can be
nice.

However, mixing the two techniques is confusing.  You can't use the
"accumulate" technique with functions designed for the "check
separately" technique.  You can use the "check separately" technique
with functions designed for the "accumulate" technique, but then
error_set() can't catch you setting an error more than once.

Standardize on the "check separately" technique for now, because it's
overwhelmingly prevalent.

Markus Armbruster f9bee751be qapi: Normalize marshalling's visitor initialization and cleanup
Input and output marshalling functions do it differently.  Change them
to work the same: initialize the I/O visitor, use it, clean it up,
initialize the dealloc visitor, use it, clean it up.

This delays dealloc visitor initialization in output marshalling
functions, and input visitor cleanup in input marshalling functions.
No functional change, but the latter will be convenient when I change
the error handling.

Juan Quintela 35d08458a9 savevm: Remove all the unneeded version_minimum_id_old (rest)
After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Peter Maydell 767adce2d9 savevm: Ignore minimum_version_id_old if there is no load_state_old
At the moment we require vmstate definitions to set minimum_version_id_old
to the same value as minimum_version_id if they do not provide a
load_state_old handler. Since the load_state_old functionality is
required only for a handful of devices that need to retain migration
compatibility with a pre-vmstate implementation, this means the bulk
of devices have pointless boilerplate. Relax the definition so that
minimum_version_id_old is ignored if there is no load_state_old handler.

Note that under the old scheme we would segfault if the vmstate
specified a minimum_version_id_old that was less than minimum_version_id
but did not provide a load_state_old function, and the incoming state
specified a version number between minimum_version_id_old and
minimum_version_id. Under the new scheme this will just result in
our failing the migration.

acpi,pci,pc,virtio fixes and enhancements

This includes new unit-tests for acpi by Marcel,
hotplug for pci bridges by myself (piix only so far)
and cpu hotplug for q35.
And a bunch of fixes all over the place as usual.

I included the patch to fix memory alignment for q35
as well - even though it limits 32 bit guests to 3G (they
previously could address more memory with PAE).
To remove the limit, this will have to be fixed in seabios.

I also added self as virtio co-maintainer so I don't need
to troll the list for patches to review.

Peter Maydell 6f1ce94a29 docs/memory.txt: Clarify and expand priority/overlap documentation
The documentation of how overlapping memory regions behave and how
the priority system works was rather brief, and confusion about
priorities seems to be quite common for developers trying to understand
how the memory region system works, so expand and clarify it.
This includes a worked example with overlaps, documentation of the
behaviour when an overlapped container has "holes", and mention
that it's valid for a region to have both MMIO callbacks and
subregions (and how this interacts with priorities when it does).

Marcel Apfelbaum 8002ccd6e4 docs/memory: Explictly state that MemoryRegion priority is signed
When memory regions overlap, priority can be used to specify
which of them takes priority. By making the priority values signed
rather than unsigned, we make it more convenient to implement
a situation where one "background" region should appear only
where no other region exists: rather than having to explicitly
specify a high priority for all the other regions, we can let them take
the default (zero) priority and specify a negative priority for the
background region.

Stefan Hajnoczi 8593898109 Use qemu-project.org domain name
qemu.org is held by a third-party and no core community contributor has
access to the DNS configuration.  This leaves the website exposed to
outages due to DNS issues or IP address changes.  For example, if the
web server IP address needs to change we cannot guarantee qemu.org will
point to it!

The newer qemu-project.org domain name is owned by Anthony Liguori
<anthony@codemonkey.ws>.  You can confirm this by querying the whois
information.  Also note that the #qemu IRC channel topic already
references qemu-project.org.

Short of having a dedicated legal entity to hold the domain name on
behalf of the community, qemu-project.org seems like the safest bet.

Let's replace references to qemu.org with qemu-project.org.

Note that git-submodule(1) does not detect URL changes.  The following
commands clear out and re-initialize all submodules to ensure you are
using the latest URLs:

  $ git submodule deinit . # you'll be warned if you have local changes
  $ rm -rf .git/modules    # also clear cached .git/ directories
  $ git submodule update --init

Kevin Wolf 622f557f5a qapi-types/visit.py: Inheritance for structs
This introduces a new 'base' key for struct definitions that refers to
another struct type. On the JSON level, the fields of the base type are
included directly into the same namespace as the fields of the defined
type, like with unions. On the C level, a pointer to a struct of the
base type is included.
