When a 'cont' is issued on a VM that's just waiting for an incoming
migration, the VM reboots and boots into the guest, possibly corrupting
its storage since it could be shared with another VM running elsewhere.
Ensure that a VM started with '-incoming' is only run when an incoming
migration successfully completes.
A new qerror, QERR_MIGRATION_EXPECTED, is added to signal that 'cont'
failed due to no incoming migration has been attempted yet.

New struct Location holds a location. So far, the only location is
LOC_NONE, so this doesn't do anything useful yet.
Passing the current location all over the place would be too
cumbersome. Hide it away in static cur_loc instead, and provide
accessors. Print it in error_report().
Store it in QError, and print it in qerror_print().
Store it in QemuOpt, for use by qemu_opts_foreach(). This makes
error_report() do the right thing when it runs within
qemu_opts_foreach().
We may still have to store it in other data structures holding user
input for better error messages. Left for another day.
Commits c7c338c4, 41471a23, 7a046f5f and a488be27 used

Only QERR_QMP_BAD_INPUT_OBJECT is QMP specific, the others can
be used in different contexts by other subsystems.
Please, note that QERR_JSON_PARSING signals any parsing error
from the json parser. We will need it until the parser gets
updated to use QError.
