This patch series convert the savevm command into qapi and introduce QMP
command vm-snapshot-save.
It also rewrite error report for functions used by this command.
The last patch introduce new functionality of savevm that you cannot override
existing snapshot without using 'force' parameter.
If non-blocking behaviour of this command is required and we cannot wait
until live snapshots will be finished, I could improve this basic command
to be non-blocking.
Changes from v3:
- correct hopefully all error messages
- proper commit message for 'qapi: Convert savevm'
Changes from v2:
- correct error messages
- introduce of 'force' option moved to qapi: Convert savevm
- update of return value for used functions
- drop of the speed improve because it isn't actually speed improve
- vm-snapshot-save and savevm now returns snapshot information
Changes from v1:
- rebase on current master branch
- improve the speed of savevm
- name parameter remains optionl for HMP and QMP
