358dbf8457 virbuffer: fix build on rhel-6
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.

aeb5262e43 Strip control codes in virBufferEscapeString
These cannot be represented in XML.

We have been stripping them, but only if the string had
characters that needed escaping: <>"'&

Extend the strcspn check to include control codes, and strip
them even if we don't do any escaping.

6ff59cbc83 util: buffer: Add support for adding text blocks with indentation
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.

Change it so it really *always* eats the @toadd buffer.

83c5467ee9 util: Introduce virBufferAddBuffer
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)

7be41e787d util: buffer: Clarify scope of the escape operation in virBufferEscape
The escaping is applied only to the string, not the format argument.
State this fact in the docs.

d194d6e7e6 maint: use consistent if-else braces in remaining spots
I'm about to add a syntax check that enforces our documented
HACKING style of always using matching {} on if-else statements.

This patch focuses on all remaining problems, where there weren't
enough issues to warrant splitting it further.

058d89b9df Introduce virBufferCheckError
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.

1b0bc4169f maint: avoid 'const fooPtr' in several util files
'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.
* src/util/virmacaddr.c (virMacAddrCmp, virMacAddrCmpRaw)
(virMacAddrSet, virMcAddrFormat, virMacAddrIsUnicast)

d0d0413e48 util: switch virBufferTrim to void
We don't care whether the trim was succesful or not anywhere
except the tests.

Switch it to void and set the buffer error on wrong usage.

79611c5968 util: Check for negative indent in virBufferAdd
Since virBufferGetIndent() will check and fail on buf->error, I
removed that check from virBufferAdd() and used the -1 return as the
way to exit.
