These are never seen externally, only passed into libvirt APIs, so in
practice this makes no real difference, but it's good to be
consistent.

Again completely mechanical, but a lot of lines.

Completely mechanical changes, but there were a lot of lines so I made
it a separate patch.

There were a lot of changes here, but all very mechanical. For some
reason, the virBufferPtr had been named "xml" instead of "buf" in this
file, so since the indentation changing touched almost every line
using the buffer, I took this chance to change its name for "buf" for
consistency with every other file.

This file was using multiple virBuffers, inserting the contents of
buf3 into buf2, then inserting the contents of buf2 into buf1, rather
than the more conventional method of just passing around a single
virBufferPtr and streaming everything into that single buffer. This
was unnecessary, and also made it more difficult to make indentation
relative, because when you insert a string into a buffer, the
indentation of the buffer is only applied once at the beginning of the
string, *not* each time a newline is encountered in the string.

These format functions needed the ability to be indented by an
arbitrary amount, but were written before the introduction of
virBufferAdjustIndent(). They instead used the much more clunky method
of adding a "level" arg to every format function, and padding with
spaces using the "%*s" printf format specifier (giving it the level,
and "", which has the effect of adding level spaces to the output).

While eliminating the hardcoded indentation in other xml, I decided it
was finally time to also modernize the interface formatter code to
make it more consistent.

This was very simple, since the only place that had hardcoded
indentation was a few items in the network status xml.

All leading spaces in domain snapshot xml format functions have been
replaced with appropriate calls to virBufferAdjustIndent(). This will
make it easier to call other similarly fixed format functions
(e.g. domain device format functions).

Many of the domain xml format functions (including all of the device
format functions) had hard-coded spaces, which made for incorrect
indentation when those functions were called in a different context
(for example, commit 2122cf39 added <interface> XML into the document
provided to a network hook script, and in this case it should have
been indented by 2 spaces, but was instead indented by 6 spaces).

To make it possible to insert a properly indented device anywhere into
an XML document, this patch removes hardcoded spaces from the
formatting functions, and calls virBufferAdjustIndent() at appropriate
places instead. (a regex search of domain_conf.c was done to assure
that all occurrences of hardcoded spaces were removed).

virDomainDiskSourceDefFormatInternal() is also called from
snapshot_conf.c, so two virBufferAdjustIndent() calls were temporarily
added around that call - those functions will have hardcoded spaces
removed in a separate patch.

This could cause some conflicts when backporting future changes to the
formatting functions to older branches, but fortunately the changes
are almost all trivial, so conflict resolution will be obvious.

Fix a problem related to rule priorities that did not allow to
have rules applied that had a higher priority than the chain they
were in. In this case the chain did not exist yet when the rule
was instantiated. The solution is to adjust the priority of rules
if the priority of the chain is of higher value. That way the chain
will be created before the rule.

Commit 6b306d66 converted virHostdevManager to a virObject, but
missed adding a virObject field to the virHostdevManager struct.
Result is memory corruption when taking a reference on an instance
of the object, where atomic inc is done on the stateDir field.
Later use of stateDir crashes libvirtd.

When I played with virtlockd I was stunned by lacking
documentation. My frustration got bigger when I had to
read the patches to get the correct value to set in
qemu.conf.

Moreover, from pure libvirt-pride  I'm changing commented
value from sanlock to lockd. We want to favor our own
implementation after all.

The kernel didn't support the unprivileged SGIO for SCSI generic
device finally, and since it's unknow whether the way to support
unprivileged SGIO for SCSI generic device will be similar as for
SCSI block device or not, even it's simliar (I.e. via sysfs, for
SCSI block device, it's /sys/dev/block/8\:0/queue/unpriv_sgio,
for example), the file name might be different, So it's better not
guess what it should be like currently.

This patch removes the related code (mainly about the "shareable"
checking on the "sgio" setting, it's not supported at all, why
we leave checking code there? :-), and error out if "sgio" is
specified in the domain config.

...and many more.  Two observations: hashstrlen was already set
to include the trailing NUL byte (so writing to hashstrlen as
the array offset was indeed writing one byte beyond bounds), and
VIR_ALLOC_N already guarantees zero-initialization (so we already
have a trailing NUL without needing to explicitly write one).

Mark many parameters as NONNULL and check for empty list of

Changes parameter from vm def to specific hostdevs info and name info, so that
