Make virtTestLoadFile allocate the buffer to read the file into.

Fix logic error in virtTestLoadFile, stop reading on the first empty line.

Use virFileReadLimFD in virtTestCaptureProgramOutput to avoid manual
buffer handling.

A few of the tests were missing basic sanity checks, while most
of them were doing copy-and-paste initialization (in fact, some
of them pasted the argc > 1 check more than once!).  It's much
nicer to do things in one common place, and minimizes the size of
the next patch that fixes getcwd usage.

Remove the <stdbool.h> header from all source files / headers
and just put it into internal.h

* src/internal.h: Add <stdbool.h>

The new names comply more with the fact that they are all members of
enum qemuCapsFlags.

QEMU supports serving VNC over a unix domain socket rather than traditional
TCP host/port. This is specified with:

<graphics type='vnc' socket='/foo/bar/baz'/>

This provides better security access control than VNC listening on
127.0.0.1, but will cause issues with tools that rely on the lax security
(virt-manager in fedora runs as regular user by default, and wouldn't be
able to access a socket owned by 'qemu' or 'root').

Also not currently supported by any clients, though I have patches for
virt-manager, and virt-viewer should be simple to update.

v2:
    schema: Make listen vs. socket a <choice>

* qemuargv2xmltest.c, qemuhelptest.c,
  qemuxml2argvtest.c, testutilsqemu.c: Update includes and
  cope with API renames

Before this patch, the testsuite was noisy:

TEST: qemuargv2xmltest
      ........................................ 40
      ................20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument '-unknown', adding to the qemu namespace
20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument 'parameter', adding to the qemu namespace
.                        57  OK
PASS: qemuargv2xmltest

It's not a real failure (which is why the test was completing
successfully), so much as an intentional warning to the user that use
of the qemu namespace has the potential for undefined effects that
leaked through the default logging behavior.  After this patch series,
all tests can access any logged data, and this particular test can
explicitly check for the presence or absence of the warning, such that
the test output becomes:

TEST: qemuargv2xmltest
      ........................................ 40
      .................                        57  OK
PASS: qemuargv2xmltest

* tests/testutils.h (virtTestLogContentAndReset): New prototype.
* tests/testutils.c (struct virtTestLogData): New struct.
(virtTestLogOutput, virtTestLogClose, virtTestLogContentAndReset):
New functions.
(virtTestMain): Always capture log data emitted during tests.
* tests/qemuargv2xmltest.c (testCompareXMLToArgvHelper, mymain):
Use flag to mark which tests expect noisy stderr.
(testCompareXMLToArgvFiles): Add parameter to test whether stderr
was appropriately silent.

Since commit 107a7bd0, the extraFlags argument was unused.

* tests/qemuargv2xmltest.c (DO_TEST): Drop extraFlags argument.
Adjust all callers.

Thanks to DV for knocking together the Relax-NG changes
quickly for me.

Changes since v1:
 - Change the domain.rng to correspond to the new schema
 - Don't allocate caps->ns in testQemuCapsInit since it is a static table

Changes since v2:
 - Change domain.rng to add restrictions on allowed environment names

Changes since v3:
 - Remove a bogus comment in the tests

The QEMU flags are commonly stored as a signed or unsigned int,
allowing only 31 flags. This limit is rather close, so to aid
future patches, change it to a 64-bit int

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c,
  tests/qemuargv2xmltest.c, tests/qemuhelptest.c, tests/qemuxml2argvtest.c:
  Use 'unsigned long long' for QEMU flags

The current QEMU code allocates PCI addresses incrementally starting
at 4. This is not satisfactory because the user may have given some
addresses in their XML config, which need to be skipped over when
allocating addresses to remaining devices.

It is thus neccessary to maintain a list of already allocated PCI
addresses and then only allocate ones that remain unused. This is
also required for domain device hotplug to work properly later.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating
  list of existing PCI addresses, and allocating new addresses.
  Refactor address assignment to use this code
* src/qemu/qemu_driver.c: Pull PCI address assignment up into the
  qemuStartVMDaemon() method, as a prelude to moving it into the
  'define' method. Update list of allocated addresses when connecting
  to a running VM at daemon startup.
* tests/qemuxml2argvtest.c, tests/qemuargv2xmltest.c,
  tests/qemuxml2xmltest.c: Remove USB product test since all
  passthrough is done based on address
* tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.args,
  tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.xml: Kil
  unused data files

QEMU always configures a VGA card. If no video card is included in
the libvirt XML, it is neccessary to explicitly turn off the default
using -vga none

* src/qemu/qemu_conf.c: Pass -vga none if no video card is configured
* tests/qemuargv2xmltest.c, tests/qemuxml2argvtest.c: Test for
  handling -vga none.
* tests/qemuxml2argvdata/qemuxml2argv-nographics-vga.args,
  tests/qemuxml2argvdata/qemuxml2argv-nographics-vga.xml: Test

Nearly all of the methods in src/util/util.h have error codes that
must be checked by the caller to correct detect & report failure.
Add ATTRIBUTE_RETURN_CHECK to ensure compile time validation of
this

* daemon/libvirtd.c: Add explicit check on return value of virAsprintf
* src/conf/domain_conf.c: Add missing check on virParseMacAddr return
  value status & report error
* src/network/bridge_driver.c: Add missing OOM check on virAsprintf
  and report error
* src/qemu/qemu_conf.c: Add missing check on virParseMacAddr return
  value status & report error
* src/security/security_selinux.c: Remove call to virRandomInitialize
  that's done in libvirt.c already
* src/storage/storage_backend_logical.c: Add check & log on virRun
  return status
* src/util/util.c: Add missing checks on virAsprintf/Run status
* src/util/util.h: Annotate all methods with ATTRIBUTE_RETURN_CHECK

* src/xen/xm_internal.c: Add missing checks on virAsprintf
* tests/qemuargv2xmltest.c: Remove bogus call to virRandomInitialize()

This adds simple support for configuring a guest with a QEMU/KVM
virtual hardware watchdog device.

* tests/qemuargv2xmltest.c, tests/qemuxml2argvtest.c: Free

PCI device assignment is only supported in KVM's fork of qemu, so we
should really detect its availability and give a nice error if its
not supported.
