After processing the option string with the keyval parser, we get a
QDict that contains only strings. This QDict must be fed to a keyval
visitor which converts the strings into the right data types.
qmp_object_add(), however, uses the normal QObject input visitor, which
expects a QDict where all properties already have the QType that matches
the data type required by the QOM object type.
Change the --object implementation in qemu-storage-daemon so that it
doesn't call qmp_object_add(), but calls user_creatable_add_dict()
directly instead and pass it a new keyval boolean that decides which
visitor must be used.

The QMP handler qmp_object_add() and the implementation of --object in
qemu-storage-daemon can share most of the code. Currently,
qemu-storage-daemon calls qmp_object_add(), but this is not correct
because different visitors need to be used.
As a first step towards a fix, make qmp_object_add() a wrapper around a
new function user_creatable_add_dict() that can get an additional
parameter. The handling of "props" is only required for compatibility
and not required for the qemu-storage-daemon command line, so it stays
in qmp_object_add().

This object may be used to represent a clock inside a clock tree.
A clock may be connected to another clock so that it receives update,
through a callback, whenever the source/parent clock is updated.
Although only the root clock of a clock tree controls the values
(represented as periods) of all clocks in tree, each clock holds
a local state containing the current value so that it can be fetched
independently. It will allows us to fullfill migration requirements
by migrating each clock independently of others.

NRF51_GPIO_REG_CNF_END doesn't actually refer to the start of the last
valid CNF register: it's referring to the last byte of the last valid
CNF register.
This hasn't been a problem up to now, as current implementation in
memory.c turns an unaligned 4-byte read from 0x77f to a single byte read
and the qtest only looks at the least-significant byte of the register.
But when running with patches which fix unaligned accesses in memory.c,
the qtest breaks.
Considering NRF51 doesn't support unaligned accesses, the simplest fix
is to actually set NRF51_GPIO_REG_CNF_END to the start of the last valid
CNF register: 0x77c.
Now, qtests work with or without the unaligned access patches.

This patch adds an optional function pointer, "sym_cb", to
riscv_load_firmware() which provides the possibility to access
the symbol table during kernel loading.
The pointer is ignored, if supplied with flat (non-elf) firmware image.
The Spike board requires it locate the HTIF symbols from firmware ELF
passed via "-bios" option.

At present the board serial number is hard-coded to 1, and passed
to OTP model during initialization. Firmware (FSBL, U-Boot) uses
the serial number to generate a unique MAC address for the on-chip
ethernet controller. When multiple QEMU 'sifive_u' instances are
created and connected to the same subnet, they all have the same
MAC address hence it creates a unusable network.
A new "serial" property is introduced to specify the board serial
number. When not given, the default serial number 1 is used.
