This patch series is bunch of cleanups to the hmp monitor code.
It mostly moves the blockdev related hmp handlers to its own file,
and does some minor refactoring.
No functional changes expected.
Changes from V1:
* move the handlers to block/monitor/block-hmp-cmds.c
* tiny cleanup for the commit messages
Changes from V2:
* Moved all the function prototypes to new header (blockdev-hmp-cmds.h)
* Set the license of blockdev-hmp-cmds.c to GPLv2+
* Moved hmp_snapshot_* functions to blockdev-hmp-cmds.c
* Moved hmp_drive_add_node to blockdev-hmp-cmds.c
(this change needed some new exports, thus in separate new patch)
* Moved hmp_qemu_io and hmp_eject to blockdev-hmp-cmds.c
* Added 'error:' prefix to vreport, and updated the iotests
This is invasive change, but really feels like the right one
* Added minor refactoring patch that drops an unused #include
Changes from V3:
* Dropped the error prefix patches for now due to fact that it seems
that libvirt doesn't need that after all. Oh well...
I'll send them in a separate series.
* Hopefully correctly merged the copyright info the new files
Both files are GPLv2 now (due to code from hmp.h/hmp-cmds.c)
* Addressed review feedback
* Renamed the added header to block-hmp-cmds.h
* Got rid of checkpatch.pl warnings in the moved code
(cosmetic code changes only)
* I kept the reviewed-by tags, since the changes I did are minor.
I hope that this is right thing to do.
Best regards,
Maxim Levitsky

usb/dev-storage: remove unused include
monitor/hmp: uninline add_init_drive
monitor/hmp: rename device-hotplug.c to block/monitor/block-hmp-cmds.c
monitor/hmp: move hmp_drive_del and hmp_commit to block-hmp-cmds.c
monitor/hmp: move hmp_drive_mirror and hmp_drive_backup to
block-hmp-cmds.c Moved code was added after 2012-01-13, thus under
GPLv2+
monitor/hmp: move hmp_block_job* to block-hmp-cmds.c
monitor/hmp: move hmp_snapshot_* to block-hmp-cmds.c
hmp_snapshot_blkdev is from GPLv2 version of the hmp-cmds.c thus
have to change the licence to GPLv2
monitor/hmp: move hmp_nbd_server* to block-hmp-cmds.c
monitor/hmp: move remaining hmp_block* functions to block-hmp-cmds.c
monitor/hmp: move hmp_info_block* to block-hmp-cmds.c
monitor/hmp: Move hmp_drive_add_node to block-hmp-cmds.c

This is only used by hmp_drive_add.
The code is just a bit shorter this way.
No functional changes

These days device-hotplug.c only contains the hmp_drive_add
In the next patch, rest of hmp_drive* functions will be moved
there.
Also add block-hmp-cmds.h to contain prototypes of these
functions
License for block-hmp-cmds.h since it contains the code
moved from sysemu.h which lacks license and thus according
to LICENSE is under GPLv2+

OK, so if we can get some block people to say they're happy, then
I'd be happy to take this through HMP or they can take it through block.
