Preserve extended attributes when copying files using dracut-install.
The copying of extended attributes avoids file execution denials when
the Linux Integrity Measurement's Appraisal mode is active. In that mode
executables need their file signatures copied. In particular, this patch
solves the problem that dependent libaries are not included in the
initramfs since the copied programs could not be executed due to missing
signatures. The following audit record shows the type of failure that
is now prevented:

IMA validates file signatures based on the security.ima xattr. As of
Linux-4.7, instead of cat'ing the IMA policy into the securityfs policy,
the IMA policy pathname can be written, allowing the IMA policy file
signature to be validated.
This patch first attempts to write the pathname, but on failure falls
back to cat'ing the IMA policy contents .

bnx2x can take no longer than 3 seconds to initialize the link in some setups
which can cause fipvlan to fail and thus the fcoe interface(s) won't be
created.
Add another 10 seconds to give the link enough time to initialize.

Dracut changes working directory before attempting to output files under
$DRACUT_TMPDIR , resulting in an IO failure if $DRACUT_TMPDIR is a path
relative to the working directory when dracut was started.

This is a further improvement on PR #105 which re-adds support for nfs:// urls to root=live:nfs://... Symptoms prior to applying this patch are that sysroot.mount times out when following the nfs:// syntax for the path to the live image. An additional case is added to livenet-generator to support the nfs protocol.

use inst() instead of inst_simple()
/etc/pki/tls/certs/ca-bundle.crt is a symlink to
../../ca-trust/extracted/pem/tls-ca-bundle.pem
with inst() we install the original file also.

add check_vol_slaves_all to be used in check_block_and_slaves_all
otherwise only the first lvm VG member would be processed
