uhci: use bottom half
Schedule bottom half on completion of async packets instead of calling
uhci_process_frame directly. This way we run uhci_process_frame only
once in case multiple packets finish in a row. Also check whenever
there is bandwidth left before scheduling uhci_process_frame.

uhci: fix bandwidth management
uhci_process_frame() can be invoked multiple times per frame, so
accounting usb bandwith in a local variable doesn't fly, use a variable
in UHCIState instead. Also check the limit more frequently.

This is not a full QAPI conversion, but an intermediate step.
In essence, do_netdev_add() is split into three functions:
1. netdev_add(): performs the actual work. This function is fully
converted to Error (thus, it's "qapi-friendly")
2. qmp_netdev_add(): the QMP front-end for netdev_add(). This is
coded by hand and not auto-generated (gen=no in the schema). The
reason for this it's a lot easier and simpler to with QemuOpts
this way

qemu-option: qemu_opts_create(): use error_set()
This commit converts qemu_opts_create() from qerror_report() to
error_set().
Currently, most calls to qemu_opts_create() can't fail, so most
callers don't need any changes.
The two cases where code checks for qemu_opts_create() erros are:
1. Initialization code in vl.c. All of them print their own
error messages directly to stderr, no need to pass the Error
object
2. The functions opts_parse(), qemu_opts_from_qdict() and
qemu_chr_parse_compat() make use of the error information and
they can be called from HMP or QMP. In this case, to allow for
incremental conversion, we propagate the error up using
qerror_report_err(), which keeps the QError semantics

introduce a new monitor command 'dump-guest-memory' to dump guest's memory
The command's usage:
dump-guest-memory [-p] protocol [begin] [length]
The supported protocol can be file or fd:
1. file: the protocol starts with "file:", and the following string is
the file's path.
2. fd: the protocol starts with "fd:", and the following string is the
fd's name.
Note:
1. If you want to use gdb to process the core, please specify -p option.
The reason why the -p option is not default is:
a. guest machine in a catastrophic state can have corrupted memory,
which we cannot trust.
b. The guest machine can be in read-mode even if paging is enabled.
For example: the guest machine uses ACPI to sleep, and ACPI sleep
state goes in real-mode.
2. If you don't want to dump all guest's memory, please specify the start
physical address and the length.
