I am adding braces around the for statement that are now needed to due the
new sa_assert immediately following the for statement.

Triggered by gnulib when compiling with MinGW.

* This patch implements a memory allocator to obtain memory for
  structures whose last member is a variable length array.  C99 refers
  to these variable length objects as structs containing flexible
  array members.
* Fixed macro parentheses per Eric Blake

* src/util/conf.c (virConfParseValue): Add an sa_assert.

* src/xen/xend_internal.c (xend_parse_sexp_desc_char): Add three
uses of sa_assert, each preceding a strchr(value,... to assure
clang that "value" is non-NULL.

* src/qemu/qemu_driver.c (qemudDomainAttachSCSIDisk):
Initialize "cont" to NULL, so clang knows it's set.
Add an sa_assert so it knows it's non-NULL when dereferenced.

* src/util/util.c (virGetHostnameLocalhost): Add an sa_assert
to tell clang it's ok to dereference "info" after a non-failing
getaddrinfo call.

* src/nwfilter/nwfilter_ebiptables_driver.c (ebiptablesApplyNewRules):
Don't dereference a NULL or uninitialized pointer when given
an empty list of rules.  Add an sa_assert(inst) in each loop to
tell clang that the uses of "inst[i]" are valid.

* configure.ac (STATIC_ANALYSIS): Define when run via clang's
scan-build or coverity-prevent's cov-build.
Use the CLANG_CC and COVERITY_BUILD_COMMAND envvars as witnesses.

Among some here, there is a strong aversion to the use of "assert", yet
some others think it is essential (when applied judiciously) even --
perhaps "especially" -- at the heart of libraries and core hypervisor-
related code.
Here is a compromise that lets us make assertions about the code (e.g.,
to tell static analyzers about invariants) without even a hint of risk
of an abort.
* src/internal.h [STATIC_ANALYSIS]: Include <assert.h>.
(sa_assert): Define.  A no-op most of the time, but equivalent
to classical assert when STATIC_ANALYSIS is nonzero.

* src/esx/esx_vi_methods.h: Placate cppi.

* tests/virt-aa-helper-test (testme): Use printf instead.

* tests/schematestutils.sh: Use printf rather than echo -e.

* src/storage/storage_backend_fs.c (virStorageBackendFileSystemMount):
Use virAsprintf only when needed.  In this case, strdup works fine.

* src/storage/storage_backend_fs.c (virStorageBackendFileSystemMount):
Clang was not smart enough, and mistakenly reported that "options"
could be used uninitialized.  Initialize it.

Somehow the backend of this function was never implemented in
libvirt's netcf driver, and nobody noticed until now. (The required
netcf function was already in place, so nothing needs to change
there.)
* src/interface/netcf_driver.c: add in the backend function, and point
                                to it from the table of driver functions.

* src/openvz/openvz_driver.c (openvzGetProcessInfo): Reorganize
so that unexpected /proc/vz/vestat content cannot make us use
uninitialized variables.  Without this change, an input line with
a matching "readvps", but fewer than 4 numbers would result in our
using at least "systime" uninitialized.

* tools/virsh.c (vshCommandRun): Test only the initial value of
ctl->timing, so that static analyzers don't have to consider that
it might be changed by cmd->def->handler.

I am getting rid of determining the path to necessary CLI tools at
compile time. Instead, now the firewall driver has an initialization
function that uses virFindFileInPath() to determine the path to
necessary CLI tools and a shutdown function to free allocated memory.
The rest of the patch mostly deals with availability of the CLI tools
and to not call certain code blocks if a tool is not available and that
strings now have to be built slightly differently.

Generate almost all SOAP method mapping code.

Update the driver code to use the complete paramater list of some methods
that had parameters skipped before.

Improve the ESX_VI__METHOD marco to do automatic output deserialization
based on output occurrence. Also incorporate automatic _this binding and
output pointer check.

* src/esx/esx_vmx.c (esxVMX_GatherSCSIControllers): Do not dereference
a NULL disk->driverName.  We already detect this condition in another
case.  Check for it here, too.

When building libvirt on RHEL-5, I saw this error:

cc1: warnings being treated as errors
openvz/openvz_conf.c: In function 'openvzGetVPSUUID':
openvz/openvz_conf.c:835: warning: 'saveptr' may be used uninitialized in this function
make[3]: *** [libvirt_driver_openvz_la-openvz_conf.lo] Error 1

gcc in RHEL-5 gets upset about this usage of strtok_r (even though
it is perfectly valid).  Just set *saveptr to NULL at the
start to quiet it down.

Changes from v1 to v2:
- changed function name prefixes to 'iface' from previous 'Iface'

- Further to make make syntax-check pass:
 - indentation fix in interface.h
 - added entry to POTFILES.in

I am consolidating network interface related functions used in nwfilter
and macvtap code in utils/interface.c. All function names are prefixed
with 'Iface'. The following functions are now available through
interface.h:

int ifaceCtrl(const char *name, bool up);
int ifaceUp(const char *name);
int ifaceDown(const char *name);

int ifaceCheck(bool reportError, const char *ifname,
               const unsigned char *macaddr, int ifindex);

int ifaceGetIndex(bool reportError, const char *ifname, int *ifindex);

I added 'int ifindex' as parameter to ifaceCheck to the original
function and modified the code accordingly.

The nodeinfotest was reliant on the host NUMA topology, but all
the test data files assumed 1 single NUMA node. This test thus
failed on any NUMA machine with > 1 node

* tests/nodeinfotest.c: Hardcode 1 single numa node

Without this module, attempts to sleep for 1 or more seconds
on mingw instead become a no-delay no-op.

* bootstrap.conf (gnulib_modules): Add usleep.

* libvirt.spec.in: fix a cut and paste error

* .x-sc_prohibit_gettext_noop: Add new exemption.
* .x-sc_prohibit_test_minus_ao: Likewise.
* Makefile.am (EXTRA_DIST): Distribute new files.
* .gitignore: Ignore built file.

With Eric Blake's spelling corrections applied.

Unfortunately after the 0.8.0 release, but here's a beginning of the
documentation of the nwfilter functionality.

* configure.ac docs/news.html.in libvirt.spec.in src/libvirt_public.syms:
  updates for release of 0.8.0
* po/*.po po/libvirt.pot: updated a lar set of localizations, and merge
  the messages

* docs/sitemap.html.in: add in navigation under
  Documentation/Deployment/Hooks
* docs/hooks.html.in: new doc describing current support for 0.8.0

* tools/virsh.pod: add two missing 's' and section about 'dominfo' is
  duplicated

This patch fixes a memory leak on daemon init and shutdown. The module
was initialized twice and not shut down.

I mistakenly took the op field in the DHCP message as the DHCP_OFFER
type. Rather than basing the decision to read the VM's IP address on
that field, process the appended DHCP options where option 53 indicates
the actual type of the packet. I am also reading the broadcast address
of the VM, but don't use it so far.

* Dan Kenigsberg requested explicit support for the qemu default disk error policy which is enospace
