Since commit 8eb55d782a2b9afacc7938694891cc6fad7b42a5 libxml2 removes
two slashes from the URI when there is no server part. This is fixed
with beb7281055dbf0ed4d041022a67c6c5cfd126f25, but only if the calling
application calls xmlSaveUri() on URI that xmlURIParse() parsed. And
that is not the case in virURIFormat(). virURIFormat() accepts
virURIPtr that can be created without parsing it and we do that when we
format network storage paths for gluster for example. Even though
virStorageSourceParseBackingURI() uses virURIParse(), it throws that data
structure right away.
Since we want to format URIs as URIs and not absolute URIs or opaque
URIs (see RFC 3986), we can specify that with a special hack thanks to
commit beb7281055dbf0ed4d041022a67c6c5cfd126f25, by setting port to -1.
This fixes qemuxml2argvtest test where the disk-drive-network-gluster
case was failing.

Replace:
if (virBufferError(&buf)) {
virBufferFreeAndReset(&buf);
virReportOOMError();
...
}
with:
if (virBufferCheckError(&buf) < 0)
...
This should not be a functional change (unless some callers
misused the virBuffer APIs - a different error would be reported
then)
Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

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.
The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

This is a follow up patch of commit f9ce7dad6, it modifies all
the files which declare the copyright like "See COPYING.LIB for
the License of this software" to use the detailed/consistent one.
And deserts the outdated comments like:
* libvirt-qemu.h:
* Summary: qemu specific interfaces
* Description: Provides the interfaces of the libvirt library to handle
* qemu specific methods
*
* Copy: Copyright (C) 2010, 2012 Red Hat, Inc.
Uses the more compact style like:
* libvirt-qemu.h: Interfaces specific for QEMU/KVM driver
*
* Copyright (C) 2010, 2012 Red Hat, Inc.
This removes nearly all the per-file error reporting macros
from the code in src/util/. A few custom macros remain for the
case, where the file needs to report errors with a variety of
different codes or parameters

When qparams support was dropped in commit bc1ff160, we forgot
to add tests to ensure that viruri can do the same round trip
handling of a URI. This round trip was broken, due to use
of the old 'query' field of xmlUriPtr, instead of the new
'query_raw'
Also, we forgot to report an OOM error.
* tests/viruritest.c (mymain): Add tests based on just-deleted
qparamtest.
(testURIParse): Allow difference in input and expected output.
* src/util/viruri.c (virURIFormat): Add missing error. Use
query_raw, instead of query for xmlUriPtr object.
Avoid the need for each driver to parse query parameters itself
by storing them directly in the virURIPtr struct. The parsing
code is a copy of that from src/util/qparams.c The latter will
be removed in a later patch
* src/util/viruri.h: Add query params to virURIPtr
* src/util/viruri.c: Parse query parameters when creating virURIPtr
* tests/viruritest.c: Expand test to cover params

Instead of just typedef'ing the xmlURIPtr struct for virURIPtr,
use a custom libvirt struct. This allows us to fix various
problems with libxml2. This initially just fixes the query vs
query_raw handling problems.

Since we defined a custom virURIPtr type, we should use a

a typedef for xmlURIPtr

Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.
File changes:
- src/util/viruri.h -- declaration
- src/util/viruri.c -- definition
- src/libvirt_private.syms -- symbol export
- src/Makefile.am -- added source and header files
- cfg.mk -- added sc_prohibit_xmlURI
- all others -- ID name and include fixes
