This initial commit does not attempt to implement exception

* ICSR.VECTPENDING was 16 too high if the pending exception
was for an external interrupt

We were incorrectly implementing soft reset and hard reset

that we were clearing the bits that soft-reset is supposed
to preserve and not touching the bits that soft-reset clears.
This was not correct behaviour for either kind of reset.

cputlb: Don't assume do_unassigned_access() never returns
In get_page_addr_code(), if the guest PC doesn't correspond to RAM
then we currently run the CPU's do_unassigned_access() hook if it has
one, and otherwise we give up and exit QEMU with a more-or-less
useful message. This code assumes that the do_unassigned_access hook
will never return, because if it does then we'll plough on attempting
to use a non-RAM TLB entry to get a RAM address and will abort() in
qemu_ram_addr_from_host_nofail(). Unfortunately some CPU
implementations of this hook do return: Microblaze, SPARC and the ARM
v7M.
Change the code to call report_bad_exec() if the hook returns, as
well as if it didn't have one. This means we can tidy it up to use
the cpu_unassigned_access() function which wraps the "get the CPU
class and call the hook if it has one" work, since we aren't trying
to distinguish "no hook" from "hook existed and returned" any more.
This brings the handling of this hook into line with the handling
used for data accesses, where "hook returned" is treated the
same as "no hook existed" and gets you the default behaviour.

bcm2835_rng: Use qcrypto_random_bytes() rather than rand()
Switch to using qcrypto_random_bytes() rather than rand() as
our source of randomness for the BCM2835 RNG.
If qcrypto_random_bytes() fails, we don't want to return the guest a
non-random value in case they're really using it for cryptographic
purposes, so the best we can do is a fatal error. This shouldn't
happen unless something's broken, though.
In theory we could implement this device's full FIFO and interrupt
semantics and then just stop filling the FIFO. That's a lot of work,
though, and doesn't really give a very nice diagnostic to the user
since the guest will just seem to hang.

ui: Use XkbGetMap and XkbGetNames instead of XkbGetKeyboard
XkbGetKeyboard does not work in XWayland and even on non-Wayland
X11 servers its use is discouraged:
https://bugs.freedesktop.org/show_bug.cgi?id=89240
This resolves a problem whereby QEMU prints
"could not lookup keycode name"
on startup when running under XWayland. Keymap handling is
however still broken after this commit, since Xwayland is
reporting a keymap we can't handle
"unknown keycodes `(unnamed)', please report to qemu-devel@nongnu.org"
NB, native Wayland support (which is the default under GTK3) is
not affected - only XWayland (which can be requested with GDK_BACKEND
on GTK3, and is the only option for GTK2).
