bceae7697f qapi script: support enum type as discriminator in union
By default, any union will automatically generate a enum type as
"[UnionName]Kind" in C code, and it is duplicated when the discriminator
is specified as a pre-defined enum type in schema. After this patch,
the pre-defined enum type will be really used as the switch case
condition in generated C code, if discriminator is an enum field.

b86b05ed60 qapi script: check correctness of union
Since line info is remembered as QAPISchema.line now, this patch
uses it as additional info for every expr in QAPISchema inside qapi.py,
then improves error message with it in checking of exprs.

For common union the patch will check whether base is a valid complex
type if specified. For flat union it will check whether base presents,
whether discriminator is found in base, whether the key of every branch
is correct when discriminator is an enum type.

949ceeb31b qapi: Clean up null checking in generated visitors
Visitors get passed a pointer to the visited object.  The generated
visitors try to cope with this pointer being null in some places, for
instance like this:

    visit_start_optional(m, obj ? &(*obj)->has_name : NULL, "name", &err);

visit_start_optional() passes its second argument to Visitor method
start_optional.  Three out of three methods dereference it
unconditionally.

I fail to see how this pointer could legitimately be null.

All this useless null checking is highly redundant, which Coverity
duly reports.  About 200 times.

Remove the useless null checks.

e26110cfc6 module: implement module loading
This patch adds loading, stamp checking and initialization of modules.

The init function of dynamic module is no longer directly called as
__attribute__((constructor)) in static linked version, it is called
only after passed the checking of presense of stamp symbol:

    qemu_stamp_$RELEASEHASH

where $RELEASEHASH is generated by hashing version strings and content
of configure script.

With this, modules built from a different tree/version/configure will
not be loaded.

The module loading code requires gmodule-2.0.

Modules are searched under
 - CONFIG_MODDIR
 - executable folder (to allow running qemu-{img,io} in the build
   directory)
 - ../ of executable folder (to allow running system emulator in the
   build directory)

Modules are linked under their subdir respectively, then copied to top
level of build directory for above convinience, e.g.:
    $(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so

ff9ec34de8 QMP: allow JSON dict arguments in qmp-shell
qmp-shell hides the QMP wire protocol JSON encoding from the user.  Most
of the time this is helpful and makes the command-line human-friendly.

Some QMP commands take a dict as an argument.  In order to express this
we need to revert back to JSON notation.

This patch allows JSON dict arguments in qmp-shell so commands like
blockdev-add and nbd-server-start can be invoked:

  (QEMU) blockdev-add options={"driver":"file","id":"drive1",...}

Note that spaces are not allowed since str.split() is used to break up
the command-line arguments first.

736ec1677f trace: fix simple trace "disable" keyword
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.

3e16d14fd9 Python-lang gdb script to extract x86_64 guest vmcore from qemu coredump
When qemu dies unexpectedly, for example in response to an explicit
abort() call, or (more importantly) when an external signal is delivered
to it that results in a coredump, sometimes it is useful to extract the
guest vmcore from the qemu process' memory image. The guest vmcore might
help understand an emulation problem in qemu, or help debug the guest.

This script reimplements (and cuts many features of) the
qmp_dump_guest_memory() command in gdb/Python,

  https://sourceware.org/gdb/current/onlinedocs/gdb/Python-API.html

working off the saved memory image of the qemu process. The docstring in
the patch (serving as gdb help text) describes the limitations relative to
the QMP command.

Dependencies of qmp_dump_guest_memory() have been reimplemented as needed.
I sought to follow the general structure, sticking to original function
names where possible. However, keeping it simple prevailed in some places.

The patch has been tested with a 4 VCPU, 768 MB, RHEL-6.4
(2.6.32-358.el6.x86_64) guest:

a31a864273 acpi: add rules to compile ASL source
Detect presence of IASL compiler and use it
to process ASL source. If not there, use pre-compiled
files in-tree. Add script to update the in-tree files.

Note: distros are known to silently update iasl
so detect correct iasl flags for the installed version on each run as
opposed to at configure time.

74523b8501 i386: add ACPI table files from seabios
This adds ASL code as well as scripts for processing it,
imported from seabios git tree
commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd

Will be used for runtime acpi table generation.

Note:
This patch reuses some code from SeaBIOS, which was originally under
LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This
relicensing has been acked by all contributors that had contributed to the
code since the v2->v3 relicense. ACKs approving the v2+ relicensing are
listed below. The list might include ACKs from people not holding
copyright on any parts of the reused code, but it's better to err on the
side of caution and include them.

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

02dc4bf568 qapi-types.py: Fix enum struct sizes on i686
Unlike other list types, enum wasn't adding any padding, which caused
a mismatch between the generated struct size and GenericList struct
size. More details in a678e26cbe

This crashed qemu if calling qmp query-tpm-types for example, which
upsets libvirt capabilities probing. Reproducer on i686:

(sleep 5; printf '{"execute":"qmp_capabilities"}\n{"execute":"query-tpm-types"}\n') | ./i386-softmmu/qemu-system-i386 -S -nodefaults -nographic -M none -qmp stdio
