xmlXPathContext.

The function does not transfer errors from 'attrBuf' and 'childBuf'
arguments into 'buf', but rather reports them right away, thus we need
to make sure that it's always checked.

Quite a few parts modify the XPath context current node to shift the
scope and allow easier queries. This also means that the node needs
to be restored afterwards.
Introduce a macro based on 'VIR_AUTOCLEAN' which adds a local structure
on the stack remembering the original node along with a function which
will make sure that the node is reset when the local structure leaves
scope.

In 600462834f4ec1955a9a4 we've tried to remove Author(s): lines
from comments at the beginning of our source files. Well, in some
files while we removed the "Author" line we did not remove the
actual list of authors.

Require that all headers are guarded by a symbol named
LIBVIRT_$FILENAME
where $FILENAME is the uppercased filename, with all characters
outside a-z changed into '_'.
Note we do not use a leading __ because that is technically a
namespace reserved for the toolchain.

This introduces a syntax-check script that validates header files use a
common layout:
/*
...copyright header...
*/
<one blank line>
#ifndef SYMBOL
# define SYMBOL
....content....
#endif /* SYMBOL */
For any file ending priv.h, before the #ifndef, we will require a
guard to prevent bogus imports:
#ifndef SYMBOL_ALLOW
# error ....
#endif /* SYMBOL_ALLOW */
<one blank line>
The many mistakes this script identifies are then fixed.

Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

It's equivalent of calling virXPathString("string(.)", ctxt) but it

The virDomainGetMetadata function was designed to support also retrieval
of app specific metadata from the <metadata> element. This functionality
was never implemented originally.
