Make qemu-io commands available in the monitor

This is a prerequisite for some kind of tests. It involves reorganising the qemu-io code so that the command part can be separated and doesn't pollute the global namespace any more, so we can link it with qemu.

v2:
- Drop the QMP command, make it HMP only
- Minor review comments like typos

Kevin Wolf (16):
qemu-io: Remove unused args_command
cutils: Support 'P' and 'E' suffixes in strtosz()
qemu-io: Make cvtnum() a wrapper around strtosz_suffix()
qemu-io: Handle cvtnum() errors in 'alloc'
qemu-io: Don't use global bs in command implementations
qemu-io: Split off commands to qemu-io-cmds.c
qemu-io: Factor out qemuio_command
qemu-io: Move 'help' function
qemu-io: Move 'quit' function
qemu-io: Move qemu_strsep() to cutils.c
qemu-io: Move functions for registering and running commands
qemu-io: Move command_loop() and friends
qemu-io: Move remaining helpers from cmd.c
qemu-io: Interface cleanup
qemu-io: Use the qemu version for -V
