sheepdog: fix loadvm operation

Currently the 'loadvm' opertaion works as following:
1. switch to the snapshot
2. mark current working VDI as a snapshot
3. rely on sd_create_branch to create a new working VDI based on the snapshot

This works not the same as other format as QCOW2. For e.g,...

rbd: Fix use after free in rbd_open()

Commit a9ccedc3 frees the QemuOpts for the driver-specific options
immediately, even though it still needs the filename string that is
contained there. This doesn't work. Move the deletion of the QemuOpts to
the end of the function where its content isn't needed any more....

sheepdog: cleanup find_vdi_name

This makes 'filename' and 'tag' constant variables, and renames
'for_snapshot' to 'lock' to clear how it works.

sheepdog: add SD_RES_READONLY result code

Sheepdog returns SD_RES_READONLY when qemu sends write requests to the
snapshot vdi. This adds the result code and makes sd_strerror() print
its error reason.

sheepdog: resend write requests when SD_RES_READONLY is received

When a snapshot is taken from out side of qemu (e.g. qemu-img
snapshot), write requests to the current vdi return SD_RES_READONLY.
In this case, the sheepdog block driver needs to update the current...

sheepdog: add discard/trim support for sheepdog

The 'TRIM' command from VM that is to release underlying data storage for
better thin-provision is already supported by the Sheepdog.

This patch adds the TRIM support at QEMU part.

For older Sheepdog that doesn't support it, we return 0(success) to upper layer....
