This also fixes a problem that Cole reported on IRC where qemufirmware
test is failing on FreeBSD because QEMU driver is enabled but there's no
YAJL.

New subject: [libvirt] [PATCH 1/2] virt-yajl.m4: Drop useless check for qemu
Firstly, this code is lacking AC_REQUIRE() therefore it may
happen that this code is executed before
LIBVIRT_DRIVER_CHECK_QEMU is evaluated. Secondly, the code tries
to detect installed version of qemu to learn if it uses HMP or
QMP and enable YAJL based on that. Well, we support only QMP and
also minimal required version of qemu is 1.5.0 so the check would
have enabled yajl anyway.

Irrelevant. LIBVIRT_DRIVER_CHECK_QEMU does not actually change
the with_qemu variable. It only depends on LIBVIRT_DRIVER_ARG_QEMU
to set the default 'yes' or get the value from the command line.
Secondly, the code tries
to detect installed version of qemu to learn if it uses HMP or
QMP and enable YAJL based on that. Well, we support only QMP and
also minimal required version of qemu is 1.5.0 so the check would
have enabled yajl anyway.
IOW after this patch, not having YAJL is no longer fatal with the
default ./configure command line on systems with a QEMU binary.

Note that the default for with_qemu is still 'yes', so developers would
have to opt-in by passing --with-qemu=check
IMHO we must fix that before we push this. We aim to have our default
configure setup automatically probe things - raising a hard error by
default when yajl is missing is not desirable unless the user has
explicitly given --with-qemu=yes.

New subject: [libvirt] [PATCH 1.5/2] virt-driver-qemu.m4: Make qemu driver optional
The basic idea of our configure script is to probe for things
rather than have them enabled by default. This is even more
visible in the next commit where configure fails if qemu driver
is enabled but no yajl is found.
