5d84f5961b Add ATTRIBUTE_FALLTHROUGH for switch cases without break
In GCC 7 there is a new warning triggered when a switch
case has a conditional statement (eg if ... else...) and
some of the code paths fallthrough to the next switch
statement. e.g.

conf/domain_conf.c: In function 'virDomainChrEquals':
conf/domain_conf.c:14926:12: error: this statement may fall through [-Werror=implicit-fallthrough=]
         if (src->targetTypeAttr != tgt->targetTypeAttr)
            ^
conf/domain_conf.c:14928:5: note: here
     case VIR_DOMAIN_CHR_DEVICE_TYPE_CONSOLE:
     ^~~~
conf/domain_conf.c: In function 'virDomainChrDefFormat':
conf/domain_conf.c:22143:12: error: this statement may fall through [-Werror=implicit-fallthrough=]
         if (def->targetTypeAttr) {
            ^
conf/domain_conf.c:22151:5: note: here
     default:
     ^~~~~~~

GCC introduced a __attribute__((fallthrough)) to let you
indicate that this is intentionale behaviour rather than
a bug.

bdd6899b55 tools: Replace vshPrint with vshPrintExtra on places we forgot about
Although there already was an effort (b620bdee) to replace vshPrint occurrences
with vshPrintExtra due to '--quiet' flag, there were still some leftovers. So
this patch fixes them, hopefully for good.

1bb1de83b2 virsh-edit: Make force editing usable
When editing a domain with 'virsh edit' and failing validation, the
usual message pops up:

  Failed. Try again? [y,n,f,?]:

Turning off validation can be useful, mainly for testing (but other
purposes too), so this patch adds support for relaxing definition in
virsh-edit and makes 'virsh edit <domain>' more usable.

daf27d4d82 virsh: Resolve Coverity DEADCODE
Since 0766783abb

Coverity complains that the EDIT_FREE definition results in DEADCODE.

As it turns out with the change to use the EDIT_FREE macro the call to
vir*Free() wouldn't be necessary nor would it happen...

Prior code to above commitid would :

  vir*Ptr foo = NULL;
  ...
  foo = vir*GetXMLDesc()
  ...
  vir*Free(foo);
  foo = vir*DefineXML()
  ...

And thus the free was needed.  With the change to use EDIT_FREE the
same code changed to:

  vir*Ptr foo = NULL;
  vir*Ptr foo_edited = NULL;
  ...
  foo = vir*GetXMLDesc()
  ...
  if (foo_edited)
      vir*Free(foo_edited);
  foo_edited = vir*DefineXML()
  ...

However, foo_edited could never be set in the code path - even with
all the goto's since the only way for it to be set is if vir*DefineXML()
succeeds in which case the code to allow a retry (and thus all the goto's)
never leaves foo_edited set

All error paths lead to "cleanup:" which causes both foo and foo_edited
to call the respective vir*Free() routines if set.

Free the old XML strings before overwriting them if the user
has chosen to reedit the file or force the redefinition.

1c04f99970 Remove spurious whitespace between function name & open brackets
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.

a4bcefbcff maint: Use consistent copyright.
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.

a7de052369 virsh: Allow users to reedit rejected XML

permanently lost. However, if virsh is not running within
a script we can ask user if he wants to re-edit the file
and correct the mistakes.

0766783abb virsh: Switch from generated cmd*Edit commands to nongenerated
Currently, we either generate some cmd*Edit commands (cmdPoolEdit
and cmdNetworkEdit) via sed script or copy the body of cmdEdit
(e.g. cmdInterfaceEdit, cmdNWFilterEdit, etc.). This fact makes
it harder to implement any new feature to our editing system.
Therefore switch to new implementation - define macros to:
- dump XML (EDIT_GET_XML)
- take an action if XML wasn't changed,
  usually just vshPrint() (EDIT_NOT_CHANGED)
- define new object (EDIT_DEFINE) - the edited XML is in @doc_edited
- free object defined by EDIT_DEFINE (EDIT_FREE)
and #include "virsh-edit.c"
