This series allow user to read internal snapshot's contents without qemu-img
convert.
V2:
Address Stefan's comments:
02: add 'fall through' comments in the case statement.
03: add doc about the difference of internal snapshot and backing chain
snapshot, which is used in previous '--snapshot' parameter.
Other:
01,04: rebased on upstream with conflict resolved.
v3:
Address Paolo's comments:
02: add parameter "-l snapshot_id_or_name", rename options
snapshot-load to load-snapshot, use QemuOpts.
03: rename snapshot-load to load-snapshot.
04: related change to test both -l and -L case.
05-07: add similar parameter for qemu-img convert.
Other:
01: foldered original snapshot logic into function
bdrv_snapshot_load_tmp_by_id_or_name(), since multiple
caller present in this version. Refined error message from
", reason: %s" to ": %s".
02: Refined error message from ", reason: %s" to ": %s".
03: Rename PARAM to SNAPSHOT_PARAM.
v4:
Address Eric's comments:
01: typo fix.
02: squashed patch. Use only one option -l and distiguish
the cases by the starting string.
03: remove 'eval', remove '_supported_os Linux', remove the
comments that have typo.
04: squashed patch. Add only one option -l and distiguish
the cases by the starting string.

02: Use only one option -l and distiguish the cases by
the starting string.
04: Use only one option -l and distiguish the cases by
the starting string, mark old -s as deprecated, added doc
for them.
v5:
Address Jeff's comments:
Quote image name in test cases.
v6:
Address Kevin's comments:
1: typo fix, remove device and snapshot info in error message.
2: use strstart().
3: use _require_command(), limit proto to file, since when proto=nbd
it can't work. also changed _require_command() to tip better.
4: use strstart().
6: new patch, since I found the doc missing in debugging.
v7:
Address Stefan's comments:
3: use unix socket and wait for 30s, to make the case reliable, folder
4: add missing doc change.
Other:
3,5: add label "method 1"/"method 2" in echo message, to tip better.
