The check for libfdt currently has a flaw: If there is a system libfdt, the
meson.build code initialized the fdt variable with fdt = cc.find_library(...).
However, if this libfdt is too old and there is no internal dtc module
available, it continues with "fdt" pointing to the old and unusable version.
The check later in the file that tries to detect whether libfdt is necessary
then fails to trigger:
if not fdt.found() and fdt_required.length() > 0
error('fdt not available but required by targets ' + ', '.join(fdt_required))
endif
The build fails then during compilation instead, which is of course bad
since this is quite confusing and already wasted quite some time of the user.
Thus if libfdt is not usable, we should unset the "fdt" variable immediately
again, so that the build already fails during the configuration phase.

The logic before was
if not get_option('gnutls').auto() or have_system
Which is equivalent to
if get_option('gnutls').enabled() or get_option('gnutls').disabled() or have_system
This means that the check for gnutls is performed even if gnutls is
disabled, which means that the build system will insist on having
libtasn1 if gnutls is found, even if gnutls support is disabled.
When gnutls is disabled, the check for gnutls shouldn't be performed,
to ensure that further build system logic (like the check for
libtasn1) doesn't make decisions based on the presence of gnutls,
rather than the gnutls option.
After making this change, I can successfully ./configure --disable-gnutls
on my system with gnutls installed, but not libtasn1.

Currently, the block driver whitelists are only applied for the system
emulator. All other binaries still give unrestricted access to all block
drivers. There are use cases where this made sense because the main
concern was avoiding customers running VMs on less optimised block
drivers and getting bad performance. Allowing the same image format e.g.
as a target for 'qemu-img convert' is not a problem then.
However, if the concern is the supportability of the driver in general,
either in full or when used read-write, not applying the list driver
whitelist in tools doesn't help - especially since qemu-nbd and
qemu-storage-daemon now give access to more or less the same operations
in block drivers as running a system emulator.
In order to address this, introduce a new configure option that enforces
the driver whitelist in all binaries.

Originally we preferred to use nettle over gcrypt because
gnutls already links to nettle and thus it minimizes the
dependencies. In retrospect this was the wrong criteria to
optimize for.
Currently shipping versions of gcrypt have cipher impls that
are massively faster than those in nettle and this is way
more important. The nettle library is also not capable of
enforcing FIPS compliance, since it considers that out of
scope. It merely aims to provide general purpose impls of
algorithms, and usage policy is left upto the layer above,
such as GNUTLS.
