54a401af47 libxl: split out DriverConfigInit out of DriverConfigNew
Take the parts affected by the host state out of DriverConfigNew
and put them into a separate function.

Adjust all the callers to call both functions.

f16663d58f security: Don't fail if locking a file on NFS mount fails
The way that our file locking works is that we open() the file we
want to lock and then use fcntl(fd, F_SETLKW, ...) to lock it.
The problem is, we are doing all of these as root which doesn't
work if the file lives on root squashed NFS, because if it does
then the open() fails. The way to resolve this is to make this a
non fatal error and leave callers deal with this (i.e. disable
remembering) - implemented in the previous commit.

5fddf61351 security: Don't remember seclabel for paths we haven't locked successfully
There are some cases where we want to remember the original owner
of a file but we fail to lock it for XATTR change (e.g. root
squashed NFS). If that is the case we error out and refuse to
start a domain. Well, we can do better if we disable remembering
for paths we haven't locked successfully.

256e01e59e virSecurityManagerMetadataLock: Store locked paths
So far, in the lock state we are storing only the file
descriptors of the files we've locked. Therefore, when unlocking
them and something does wrong the only thing we can report is FD
number, which is not user friendly at all. But if we store paths
among with FDs we can do better error reporting.

058b30b382 ci: Fix handling of $PKG_CONFIG_LIBDIR
There are two environment variables that are baked into our
cross-compilation container images at build time, $CONFIGURE_OPTS
and $PKG_CONFIG_LIBDIR: the former contain the options necessary
to convince configure to perform a cross build rather than a
native one, and the latter is necessary so that pkg-config will
locate the .pc files for MinGW libraries. Container images that
are not intended for cross-compilation will not have either one
defined.

The problem is that, while an empty $CONFIGURE_OPTS is completely
harmless, setting $PKG_CONFIG_LIBDIR to an emtpy value will
result in pkg-config not looking in its default search path, thus
not finding any library, and subsequently breaking native builds.

To work around this issue, only pass $PKG_CONFIG_LIBDIR to sudo
when the value is set in the calling environment.
