All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

It doesn't really make sense for us to have stdlib.h and string.h but
not stdio.h in the internal.h header.

By making use of GNU C's cleanup attribute handled by the
VIR_AUTOPTR macro for declaring aggregate pointer variables,
majority of the calls to *Free functions can be dropped, which
in turn leads to getting rid of most of our cleanup sections.

Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in
src/util/viralloc.h, define a new wrapper around an existing
cleanup function which will be called when a variable declared
with VIR_AUTOPTR macro goes out of scope. Also, drop the redundant
viralloc.h include, since that has moved from the source module into
the header.
When variables of type virBufferPtr and virBufferEscapePairPtr
are declared using VIR_AUTOPTR, the functions virBufferFreeAndReset
and virBufferEscapePairFree, respectively, will be run automatically
on them when they go out of scope.

The code was vulnerable to SQL injection. Likely not a security issue due to
WMI SQL and other constraints but still lame. For example:
virsh # dominfo \"
error: failed to get domain '"'
error: internal error: SOAP fault during enumeration: code 's:Sender', subcode
'n:CannotProcessFilter', reason 'The data source could not process the filter.
The filter might be missing or it might be invalid. Change the filter and try
the request again. ', detail 'The WS-Management service cannot process the
request. The WQL query is invalid. '
This commit fixes the Hyper-V driver by escaping all WMI SQL string parameters.
The same command with the fix:
virsh # dominfo \"
error: failed to get domain '"'
error: Domain not found: No domain with name "

On rhel-6 is broken gcc that reports this warning:
util/virbuffer.c:500: error: logical '&&' with non-zero constant will
always evaluate as true [-Wlogical-op]
Move the pragma directive before function virBufferEscapeString because
since commit aeb5262e this function uses 'strchr' too.

The current auto-indentation buffer code applies indentation only on
complete strings. To allow adding a string containing newlines and
having it properly indented this patch adds virBufferAddStr.
This API joins the following two lines:
char *s = virBufferContentAndReset(buf1);
virBufferAdd(buf2, s, -1);
into one:
virBufferAddBuffer(buf2, buf1);
With one exception: there's no re-indentation applied to @buf1.
The idea is, that in general both can have different indentation
(like the test I'm adding proves)

Check if the buffer is in error state and report an error if it is.
This replaces the pattern:
if (virBufferError(buf)) {
virReportOOMError();
goto cleanup;
}
with:
if (virBufferCheckError(buf) < 0)
goto cleanup;
Document typical buffer usage to favor this.
Also remove the redundant FreeAndReset - if an error has
been set via virBufferSetError, the content is already freed.
'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can). But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).
Fix up offenders in src/util outside of the virnet namespace.
Also, make a few virSocketAddr functions const-correct, for easier
conversions in future patches.
* src/util/virbuffer.h (virBufferError, virBufferUse)
(virBufferGetIndent): Use intended type.
* src/util/virmacaddr.h (virMacAddrCmp, virMacAddrCmpRaw)
(virMacAddrSet, virMcAddrFormat, virMacAddrIsUnicast)
(virMacAddrIsMulticast): Likewise.
* src/util/virebtables.h (ebtablesAddForwardAllowIn)
(ebtablesRemoveForwardAllowIn): Likewise.
* src/util/virsocketaddr.h (virSocketAddrSetIPv4Addr): Drop
incorrect const.
(virMacAddrGetRaw, virSocketAddrFormat, virSocketAddrFormatFull):
Make const-correct.
(virSocketAddrMask, virSocketAddrMaskByPrefix)
(virSocketAddrBroadcast, virSocketAddrBroadcastByPrefix)
(virSocketAddrGetNumNetmaskBits, virSocketAddrGetIpPrefix)
(virSocketAddrEqual, virSocketAddrIsPrivate)
(virSocketAddrIsWildcard): Use intended type.
* src/util/virbuffer.c (virBufferError, virBufferUse)
(virBufferGetIndent): Fix fallout.
