configure / meson: Move the GBM handling to meson.build

The GBM library detection does not need to be in the configure script,
since it does not have any user-facing options (there are no
--enable-gbm or --disable-gbm switches). Let's move it to meson.build
instead, so we don't have to clutter config-host.mak with the related
switches.

Additionally, only check for GBM if it is really required, i.e. if we
either compile with OpenGL or with virglrenderer support.

plugins: do not limit exported symbols if modules are active

On Mac --enable-modules and --enable-plugins are currently incompatible, because the
Apple -Wl,-exported_symbols_list command line options prevents the export of any
symbols needed by the modules. On x86 -Wl,--dynamic-list does not have this effect,
but only because the -Wl,--export-dynamic option provided by gmodule-2.0.pc overrides
it. On Apple there is no -Wl,--export-dynamic, because it is the default, and thus
no override.

Either way, when modules are active there is no reason to include the plugin_ldflags.
While at it, avoid the useless -Wl,--export-dynamic when --enable-plugins is
specified but --enable-modules is not; this way, the GNU and Apple configurations
are more similar.

fuzz: add an instrumentation filter

By default, -fsanitize=fuzzer instruments all code with coverage
information. However, this means that libfuzzer will track coverage over
hundreds of source files that are unrelated to virtual-devices. This
means that libfuzzer will optimize inputs for coverage observed in timer
code, memory APIs etc. This slows down the fuzzer and stores many inputs
that are not relevant to the actual virtual-devices.

With this change, clang versions that support the
"-fsanitize-coverage-allowlist" will only instrument a subset of the
compiled code, that is directly related to virtual-devices.

configure: Add -Werror to avx2, avx512 tests

When using clang, we get

ERROR: configure test passed without -Werror but failed with -Werror.
This is probably a bug in the configure script. The failing command
will be at the bottom of config.log.
You can run configure with --disable-werror to bypass this check.

What we really want from these two tests is whether the
entire code sequence is supported, including pragmas.
Adding -Werror makes the test properly fail for clang.

configure: Fix the default setting of the "xen" feature

The "xen" variable should either contain "enabled", "disabled" or
nothing (for auto detection). But when the user currently runs the
configure script with --without-default-features, it gets set to
"no" instead. This does not work as expected, the feature will still
be enabled if the Xen headers are present. Thus set the variable
to "disabled" instead if default_feature switch has been set.

block: Add option to use driver whitelist even in tools

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.

configure: Fix endianess test with LTO

If a user is trying to compile QEMU with link-time optimization
enabled by running the configure script like this:

.../configure --extra-cflags="-flto"

then

configure: Fix endianess test with LTO

If a user is trying to compile QEMU with link-time optimization
enabled by running the configure script like this:

.../configure --extra-cflags="-flto"

then the endianess test is failing since the magic values do not
show up in the intermediate object files there. If the host is
a big endian machine (like s390x), the QEMU binary is then unusable
since the corresponding variable "bigendian" is pre-initialized
with "no".

To fix this issue, we should rather create a full binary and look
for the magic strings there instead.
And we really should not continue the build if the endianess check
failed, to make it clear right from the start that something went
wrong here, thus let's also add some "exit 1" statements here
after emitting the error message.
