If __lxstat() and __xstat() functions are not available, build fails with:
CC virfilewrapper.o
virfilewrapper.c:180:5: error: no previous prototype for function '__lxstat' [-Werror,-Wmissing-prototypes]
int __lxstat(int ver, const char *path, struct stat *sb)
^
virfilewrapper.c:208:5: error: no previous prototype for function '__xstat' [-Werror,-Wmissing-prototypes]
int __xstat(int ver, const char *path, struct stat *sb)
Luckily, we already check presence of these functions in configure
using AC_CHECK_FUNCS, so just don't wrap these if they're not available.

We're only adding only info about L3 caches, we can add more
later (just by changing one line), but for now that's more than enough
without overwhelming anyone.

It is no longer needed thanks to the great virfilewrapper.c. And this
way we don't have to add a new set of functions for each prefixed
path.
While on that, add two functions that weren't there before, string and
scaled integer reading ones. Also increase the length of the string
being read by one to accompany for the optional newline at the
end (i.e. change INT_STRLEN_BOUND to INT_BUFSIZE_BOUND).

This mock (which is actually not mock at all, see later) can redirect
all accesses to a path into another path. There is no need to
create mocks for particular directories, you just create a directory
with all the data a redirect the test there.
In the future, this should also be able to register callbacks for
calls/paths, e.g. when the test is going to write into anything under
"/sys/devices", call function fce(); Then in the open() call we would
add information about the fd into some structure and in write() we
would call fce() with parameters like @path to write to, @data to
be written and pointer to optional return value, so that fce() itself
could stop the call from happening or change its behaviour. But
that's an idea for a latter day.
This is not a mock because it will not be preloaded, but compiled in
the test itself. See future patches for usage.

This patch maps /domain/cpu/cache element into -cpu parameters:
- <cache mode='passthrough'/> is translated to host-cache-info=on
- <cache level='3' mode='emulate'/> is transformed into l3-cache=on
- <cache mode='disable'/> is turned in host-cache-info=off,l3-cache=off
Any other <cache> element is forbidden.
The tricky part is detecting whether QEMU supports the CPU properties.
The 'host-cache-info' property is introduced in v2.4.0-1389-ge265e3e480,
earlier QEMU releases enabled host-cache-info by default and had no way
to disable it. If the property is present, it defaults to 'off' for any
QEMU until at least 2.9.0.
The 'l3-cache' property was introduced later by v2.7.0-200-g14c985cffa.
Earlier versions worked as if l3-cache=off was passed. For any QEMU
until at least 2.9.0 l3-cache is 'off' by default.
QEMU 2.9.0 was the first release which supports probing both properties
by running device-list-properties with typename=host-x86_64-cpu. Older
QEMU releases did not support device-list-properties command for CPU
devices. Thus we can't really rely on probing them and we can just use
query-cpu-model-expansion QMP command as a witness.
Because the cache property probing is only reliable for QEMU >= 2.9.0
when both are already supported for quite a few releases, we let QEMU
report an error if a specific cache mode is explicitly requested. The
other mode (or both if a user requested CPU cache to be disabled) is
explicitly turned off for QEMU >= 2.9.0 to avoid any surprises in case
the QEMU defaults change. Any older QEMU already turns them off so not
doing so explicitly does not make any harm.

A long time ago we imported the keymaps.csv file from GTK-VNC so we
can do conversions between keycode sets. Meanwhile lots of bug fixes
have gone into this CSV file and libvirt hasn't kept in sync. The
keymaps.csv file and associated generator script has been pulled out
of GTK-VNC into a dedicated GIT repo for use as a submodule. This
allows GTK-VNC, SPICE-GTK, QEMU and libvirt to share the same master
database and tools and pushing updates merely requires a submodule
commit update as with gnulib.
The test suite is updated to cover some extra boundary conditions.

We are currently parsing only rx/frames/max because that's the only
value that makes sense for us. The tun device just added support for
this one and the others are only supported by hardware devices which
we don't need to worry about as the only way we'd pass those to the
domain is using <hostdev/> or <interface type='hostdev'/>. And in
those cases the guest can modify the settings itself.

We already know from QEMU which CPU features will block migration. Let's
use this information to make a migratable copy of the host CPU model and
use it for updating guest CPU specification. This will allow us to drop
feature filtering from virCPUUpdate where it was just a hack.
