[libvirt] [PATCH v3 0/8] Introduce aliases for virt-admin's srv-* commands

v2: https://www.redhat.com/archives/libvir-list/2016-September/msg00380.html

Since this series (compared to v2) does a tiny bit of refactor (tweaking might
be a better word in this case) as well, I was also looking into refactoring the
parser in vsh.c....again...And again I gave up on doing that (this time a lot
faster though) because that would mean to rewrite a lot of code mainly to enable
usage of our virString* methods. I also found an ANSI C GNU-styled command line
parser library [1] which might even cope with our command and option aliases
(I didn't look into that much though, so take it with a grain of salt).
However, though looking good, it would most likely hit the wall once it
encountered our "multi-command" feature in the interactive shell mode :(

since v1:
    - tweaked the virsh-self-test so that it also checks the aliased commands
      instead of skipping them (since there was a good reason for that before
      the changes this series introduces)
    - patches (now) 7-8 remained untouched

since v2:
    - Michal was indeed right about having a proper check for missing aliases
      which would eventually result in a reasonable internal error
    - so the check was put into vshCmddefCheckInternals, but that function
      should not be called from within vshCmddefOptParse because it's not just
      about checking the .opts but the overall command structure and at the time
      of parsing the arguments we should already know whether the command
      structure is valid or not
    - since vshCmddefOptParse has been split once again, merge it with
      vshCmddefOptFill and drop the latter

Erik Skultety (8):
  vsh: Fix NULL dereference leading to SIGSEGV if a command is missing
    '.info'
  vsh: vshCmddefHelp: Drop the unnecessary 'else' branch
  vsh: vshCmddefHelp: Retrieve command info after we know the command is
    non-NULL
  vsh: Extract vshCmddefCheckInternals from vshCmddefOptParse
  vsh: discard vshCmddefOptFill and move its body to vshCmddefOptParse
  virt-admin: Tweak command parsing logic so that aliases point to new
    commands
  virt-admin: Add some command aliases to provide syntax sugar over ugly
    commands
  virt-admin: Replace the (now) aliases with new command names in the
    man page
