On architectures not supporting the Intel specific programmable interval
timer, like e.g. S390, starting a domain with a clock definition containing
a pit timer results in the error "Option no-kvm-pit-reinjection not supported
for this target".

By moving the capability enablement for -no-kvm-pit-reinjection from the
InitQMPBasic section into the x86_64 and i686 only enablement section all
other architectures are no longer automatically enabled. In addition
architecture related capabilities enablements have refactored into a new
architecture bound capabilities initialization function.

We have seen an issue on s390x platform where domain XMLs larger than 1MB
were used. The define command was finished successfully. The dumpxml command
was not successful (i.e. could not encode message payload).

Enlarged message related sizes (e.g. maximum string size, message size, etc.)
to handle larger system configurations used on s390x platform.

To improve handling of the RPC message size the allocation during encode process
is changed to a dynamic one (i.e. starting with 64kB initial size and increasing
that size in steps up to 16MB if the payload data is larger).

I traced it to a missing entry in EXTRA_DIST.  But rather than keep
the entire list in sync, it is easier to list the three syms files
that drive .so files directly, and then reuse existing makefile
variables for the remaining files (that is, I validated that all
remaining files are added to SYM_FILES, possibly via USED_SYM_FILES,
according to makefile conditionals).

The code adaptation is not done right now, but in subsequent patches.
Hence I am not implementing syntax-check rule as it would break
compilation. Developers are strongly advised to use these new macros.
They are similar to VIR_ALLOC() logic: VIR_STRDUP(dst, src) returns zero
on success, -1 otherwise. In case you don't want to report OOM error,
use the _QUIET variant of a macro.

Add missing 'html:' namespace prefix to a few more XSL

I must have looked at this a couple dozen times before I noticed it
had "!=" instead of "==". Not doing this setup prevented qemu from
doing anything with the vfio group device.

The previous commit failed to update the XSL to take account
of fact that in XHTML mode the elements need namespace
prefixes. This caused every web page to be blank!

The rule generating the HTML docs passing the --html flag
to xsltproc. This makes it use the legacy HTML parser, which
either ignores or tries to fix all sorts of broken XML tags.
There's no reason why we should be writing broken XML in
the first place, so removing --html and adding the XHTML
doctype to all files forces us to create good XML.

This adds the XHTML doc type and fixes many, many XML tag
problems it exposes.

In the non linux case some callers like gather_scsi_host_caps needed the
return code of -1 while others like update_caps needed an empty
statement (to avoid a "statement without effect" warning). This is much
simpler solved by using a function instead of a define.

since it uses glibc's rpcgen.

A 'uri' parameter was added for the benefit of sanlock. This
causes a warning in the lockd driver though

Recent new addition of code to read/write active network state to the
NETWORK_STATE_DIR in the network driver broke startup for
qemu:///session. The network driver had several state file paths
hardcoded to /var, which could never possibly work in session mode.

This patch modifies *all* state files to use a variable string that is
set differently according to whether or not we're running
privileged. (It turns out that logDir was never used, so it's been
completely eliminated.)

There are very definitely other problems preventing dnsmasq and radvd
from running in non-privileged mode, but it's more consistent to have
the directories used by them be determined in the same fashion.

NB: I've noted before that the network driver is storing its state
(including dnsmasq and radvd state) in /var/lib, while qemu stores its
state in /var/run. It would probably have been better if the two
matched, but it's been this way for a long time, and changing it would
break running installations during an upgrade, so it's best to just
leave it as it is.

The QEMU migration code unconditionally sets the 'persistent'
cookie flag on the source host. The dest host, however, only
allows it during parsing if VIR_MIGRATE_PERSIST_DEST was
set. Make the source host only set it if this flag is
present.

The lockd plugin for the lock manager was not correctly
handling the release of resource locks. This meant that
during migration, or when pausing a VM, the locks would
not get released. This in turn made it impossible to
resume the domain, or finish migration

The F_DUPFD_CLOEXEC operation with fcntl() expects a single
int argument, specifying the minimum FD number for the newly
dup'd file descriptor. We were not specifying that causing
random stack data to be accessed as the FD number. Sometimes
that worked, sometimes it didn't.

POSIX says pthread_t is opaque.  We can't guarantee if it is scaler
or a pointer, nor what size it is; and BSD differs from Linux.
We've also had reports of gcc complaining on attempts to cast it,
if we use a cast to the wrong type (for example, pointers have to be
cast to void* or intptr_t before being narrowed; while casting a
function return of scalar pthread_t to void* triggers a different
warning).

Give up on casts, and use unions to get at decent bits instead.  And
rather than futz around with figuring which 32 bits of a potentially
64-bit pointer are most likely to be unique, convert the rest of
the code base to use 64-bit values when using a debug id.

Based on a report by Guido Günther against kFreeBSD, but with a
fix that doesn't regress commit 4d970fd2 for FreeBSD.

commit 7c9a2d88 missed adding in a few #include "virstring.h"s, causing
builds to fail.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

It's not desired to force users imagine path for a socket they
are not even supposed to connect to. On the other hand, we
already have a release where the qemu agent socket path is
exposed to XML, so we cannot silently drop it from there.
The new path is generated in form:

$LOCALSTATEDIR/lib/libvirt/qemu/channel/target/$domain.$name

for qemu system mode, and

$XDG_CONFIG_HOME/qemu/lib/channel/target/$domain.$name

for qemu session mode.
