libgcrypt starts providing correct pkg-config configuration since 1.9,
in parallel with libgcrypt-config. Since 1.11 it may also stop
installing libgcrypt-config in some scenarios. Use the auto method for
detection of libgcrypt, in which meson will try both pkg-config and
libgcrypt-config.
Auto method for libgcrypt is supported by meson since 0.49.0, which is
higher than the version qemu requires.

We only use Libtasn1 in unit tests. As noted in commit d47b83b118
("tests: add migration tests of TLS with x509 credentials"), having
GnuTLS without Libtasn1 is a valid configuration, so do not require
Libtasn1, to avoid:
Dependency gnutls found: YES 3.7.1 (cached)
Run-time dependency libtasn1 found: NO (tried pkgconfig)
../meson.build:1914:10: ERROR: Dependency "libtasn1" not found, tried pkgconfig

Since fifo8_pop_buf() return a const buffer (which points
directly into the FIFO backing store). Rename it using the
'bufptr' suffix to better reflect that it is a pointer to
the internal buffer that is being returned. This will help
differentiate with methods *copying* the FIFO data.

Rather than using address_space_rw(..., 0 or 1),
use the simpler DMA memory API which expand to
the same code. This allows removing a cast on
the 'buf' variable which is really const. Since
'buf' is only used in the CMD_READ_BUFFER case,
we can reduce its scope.

According to the comment in qapi/error.h, dereferencing @errp requires
ERRP_GUARD():
* = Why, when and how to use ERRP_GUARD() =
*
* Without ERRP_GUARD(), use of the @errp parameter is restricted:
* - It must not be dereferenced, because it may be null.
...
* ERRP_GUARD() lifts these restrictions.
*
* To use ERRP_GUARD(), add it right at the beginning of the function.
* @errp can then be used without worrying about the argument being
* NULL or &error_fatal.
*
* Using it when it's not needed is safe, but please avoid cluttering
* the source with useless code.
In nubus_virtio_mmio_realize(), @errp is dereferenced without
ERRP_GUARD().
Although nubus_virtio_mmio_realize() - as a DeviceClass.realize()
method - is never passed a null @errp argument, it should follow the
rules on @errp usage. Add the ERRP_GUARD() there.
