The VIR_XPATH_NODE_AUTORESTORE contains an ignore_value
statement to silence an unused variable warning on clang.
Use a pragma instead, which is not a statement.

There is nothing domain specific about the function, thus it
should not have virDomain prefix. Also, the fact that it is a
static function makes it impossible to use from other files.
Move the function to virxml.c and drop the 'Domain' infix.

This was mostly boilerplate conversion, but in one case I needed to
define several differently named char* to take the place of a single
char *tmp that was re-used multiple times, and in another place there
was a single char* that was used at the toplevel of the function, and
then later used repeatedly inside a for loop, so I defined a new
separate char* inside the loop.

A function to automatically format the xmlns:<prefix>='<uri>'

Reviewed-by: Jiri Denemark <jdenemar@redhat.com>
We have hardcoded the namespace prefix in various places:
1) the xmlns string stored in the 'href' function
2) the xmlXPathRegisterNs call in each parser
3) all the parsing and formatting code actually dealing
with these elements
While eliminating the third one is probably a job for an
actual XML-aware formatter, let's store the prefix separately
here in the virXMLNamespace structure so that future patches
can get rid of the first two bullets.

Keeping them with viralloc.h forcibly pulls in the other stuff from

as more and more headers pull in the 'viral' header file.
If we want to make 'viralloc.h' omnipresent we should pick a different
approach.

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.

This introduces a syntax-check script that validates header files use a
common layout:
/*

*/
<one blank line>
#ifndef SYMBOL
# define 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.
