In most cases this eliminates one or more calls to
virBufferClearAndReset(), but even when it doesn't it's better because:
1) it makes the code more consistent, making it more likely that new
contributors who are "learning by example" will to the right thing.
2) it protects against future modifications that might have otherwise
needed to add a virBufferClearAndReset()
3) Currently some functions don't call virBufferClearAndReset() only
because they're relying on some subordinate function to call it for
them (e.g. bhyveConnectGetSysinfo() in this patch relies on
virSysinfoFormat() to clear out the buffer when there is an
error). I think this is sloppy behavior, and that the toplevel
function that defines and initializes the buffer should be the
function clearing it at the end.

This deletes all trace of gnulib from libvirt. We still
have the keycodemapdb submodule to deal with. The simple
solution taken was to update it when running autogen.sh.
Previously gnulib could auto-trigger refresh when running
'make' too. We could figure out a solution for this, but
with the pending meson rewrite it isn't worth worrying
about, given how infrequently keycodemapdb changes.

conf: add support for specifying CPU "dies" parameter
Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
Recently CPU hardware vendors have started to support a new structure
inside the CPU package topology known as a "die". Thus the hierarchy
is now:
sockets > dies > cores > threads
This adds support for "dies" in the XML parser, with the value
defaulting to 1 if not specified for backwards compatibility.
For example a system with 64 logical CPUs might report
<topology sockets="4" dies="2" cores="4" threads="2"/>

The XML parser currently calls virCapabilitiesDomainDataLookup during
parsing to find the domain capabilities matching the triple
(virt type, os type, arch)
This is, however, bogus with the QEMU driver as it assumes that there
is an emulator known to the default driver capabilities that matches
this triple. It is entirely possible for the driver to be parsing an
XML file with a custom emulator path specified pointing to a binary
that doesn't exist in the default driver capabilities. This will,
for example be the case on a RHEL host which only installs the host
native emulator to /usr/bin. The user can have built a custom QEMU
for non-native arches into $HOME and wish to use that.
Aside from validation, this call is also used to fill in a machine type
for the guest if not otherwise specified. Again, this data may be
incorrect for the QEMU driver because it is not taking account of
the emulator binary that is referenced.
To start fixing this, move the validation to the post-parse callbacks
where more intelligent driver specific logic can be applied.

Commit 5751a0b6b1 added a helper function
called virDomainCapsFeaturesInitUnsupported which initialized all domain
capability features as unsupported.
When adding a new feature this would initialize it as unsupported also
for hypervisor drivers which the original author possibly didn't intend
to modify. To prevent accidental wrong value being reported in such case
revert back to initializing individual features in the hypervisor
drivers themselves.
This is not a straight revert as additonal patches modified how we store
the capabilities.
