Based on the similar gnulib commit 96ad9077.  The use of
$(_sc_search_regexp) already injects $(ME) into any output
messages, so a failure of these rules would look like this,
pre-patch:

maint.mk: maint.mk: use virStrToLong_*, not strtol variants

* cfg.mk (sc_prohibit_strncmp, sc_prohibit_strtol)
(sc_libvirt_unmarked_diagnostics): Drop redundant $(ME).

Yesterday's commit 15d2c9fa pointed out that virsh was still using
localtime(), which is not thread-safe, even though virsh is
definitely multi-threaded.  Even if we only ever triggered it from
one thread, it's better safe than sorry for maintenance purposes.

* cfg.mk (exclude_file_name_regexp--sc_prohibit_nonreentrant):
Tighten the rule.
* tools/virsh.c (vshOutputLogFile): Avoid localtime.
(vshEditWriteToTempFile, vshEditReadBackFile, cmdCd, cmdPwd)
(vshCloseLogFile): Avoid strerror.
* tools/console.c (vshMakeStdinRaw): Likewise.
* tools/virsh-domain.c (vshGenFileName): Fix spacing in previous
patch.

Nothing in the testsuite or examples directory should be translated,
as it is not part of the normally installed binary.  We already
meet this rule, but enforcing it will make it easier to remember.

Suggested by Daniel P. Berrange.

* cfg.mk (sc_prohibit_useless_translation): Enhance rule.

* cfg.mk: Whitelist virsh.h instead of virsh.c for strcasecmp check
* tools/virsh-domain.h, tools/virsh.h: Fix #define indentation

'make distcheck' was failing because a syntax check file,
.sc-start-sc_vulnerable_makefile_CVE-2012-3386, got left
behind.  I traced it to the 'distdir' rule depending on a
shortcut syntax-check name rather than the full rule name
normally used during 'local-check' from maint.mk.

* cfg.mk (distdir): Depend on full rule, not shorthand name.

* tools/virsh.c: New macro vshStrcasecmp
* tools/virsh-domain-monitor.c: Use vshStrcasecmp instead of
                                strcasecmp
* tools/virsh-snapshot.c: Likewise
* cfg.mk: Only avoid doing strcase checking for virsh.c

This introduces a fairly basic reference counted virObject type
and an associated virClass type, that use atomic operations for
ref counting.

In a global initializer (recommended to be invoked using the
virOnceInit API), a virClass type must be allocated for each
object type. This requires a class name, a "dispose" callback
which will be invoked to free memory associated with the object's
fields, and the size in bytes of the object struct.

eg,

   virClassPtr  connclass = virClassNew("virConnect",
                                        sizeof(virConnect),
                                        virConnectDispose);

The struct for the object, must include 'virObject' as its
first member

eg

  struct _virConnect {
    virObject object;

    virURIPtr uri;
  };

The 'dispose' callback is only responsible for freeing
fields in the object, not the object itself. eg a suitable
impl for the above struct would be

  void virConnectDispose(void *obj) {
     virConnectPtr conn = obj;
     virURIFree(conn->uri);
  }

There is no need to reset fields to 'NULL' or '0' in the
dispose callback, since the entire object will be memset
to 0, and the klass pointer & magic integer fields will
be poisoned with 0xDEADBEEF before being free()d

When creating an instance of an object, one needs simply
pass the virClassPtr eg

   virConnectPtr conn = virObjectNew(connclass);
   if (!conn)
      return NULL;
   conn->uri = virURIParse("foo:///bar")

Object references can be manipulated with

   virObjectRef(conn)
   virObjectUnref(conn)

The latter returns a true value, if the object has been
freed (ie its ref count hit zero)

The cfg.mk file rule to check for tab characters was not
applied to perl files. Much of our Perl code is full of
tabs as a result. Kill them, kill them all !

Commit f9ce7dad tried to kill uses of a raw street address, but
missed a few instances.  Automate things so we don't introduce
new problems in the future.

Any time we have a string with no % passed through gettext, a
translator can inject a % to cause a stack overread.  When there
is nothing to format, it's easier to ask for a string that cannot
be used as a formatter, by using a trivial "%s" format instead.

In the past, we have used --disable-nls to catch some of the
offenders, but that doesn't get run very often, and many more
uses have crept in.  Syntax check to the rescue!

The syntax check can catch uses such as
virReportError(code,
               _("split "
                 "string"));
by using a sed script to fold context lines into one pattern
space before checking for a string without %.

This patch is just mechanical insertion of %s; there are probably
several messages touched by this patch where we would be better
off giving the user more information than a fixed string.

We were defining 'func_or' as '|VIR_ERROR|...', which when put
inside 'func_re' resulted in a regex that matches everything in
isolation.  Thankfully, we always used func_re with a leading
anchor \<, and since the empty regex does not start a word, we
happened to get the result we wanted; but it's better to define
func_or without a leading space converted into a leading empty
alternation.

* cfg.mk (func_or): Strip leading space.
