[Qemu-devel] [PATCH V5 0/2] Add JSON output to qemu-img info

[Benoît Canet]

This patchset add a JSON output mode to the qemu-img info command.
It's a rewrite from scratch of the original patchset by Wenchao Xia
following Anthony Liguori advices on JSON formating.

the --output=(json|human) option is now mandatory on the command line.

Benoît Canet (3):
  qapi: Add SnapshotInfo.
  qapi: Add ImageInfo.
  qemu-img: Add json output option to the info command.

in v2:

eblake: make some field optionals
        squash the two qapi patchs together
        fix a typo on vm_clock_nsec

bcanet: fix a potential memory leak

in v3: 

lcapitulino: 
       remove unneeded test
       put '\n' at the end of json in printf statement
       drop the uneeded head pointer in collect_snapshots

in v4:

Wenchao Xia && Kevin Wolf: -Refactor to separate rate ImageInfo
                           collection from human printing.

Kevin Wolf: -Use --output=(json|human).
            -make the two choice exclusive and print a message
            if none is specified.
            -cosmetic '=' alignement in collect snapshots.

Benoît Canet: -add full-backing-filename to the ImageInfo structure
              (needed for human printing)
              -make ImageInfo->actual_size optional depending on the
              context.
in v5:

Eric Blake: -use a constant for getopt parsing to avoid future
             short options collision.
            -make the command default to --output=human.
            -fix spurious whitespace change.
            -split vm-clock-nsec in two fields vm-clock-sec and
             vm-clock-nsec.
            -declare JSON structure as "Since 1.3"
