The default value '/' for DESTDIR is unusual, but does probably not hurt.

Blktap2 is effectively dead for a few years.
Notable changes in this patch:
0. Unhook blktap2 from build system
1. libxl no longer supports TAP disk backend, with appropriate assertions
added and some code paths now return ERROR_FAIL
2. Tap is no longer a supported backend
3. Remove blktap2 entry from MAINTAINERS
A patch to remove blktap2 directory will come later.

This adds a Kconfig option and support for including the XSM policy from
tools/flask/policy in the hypervisor so that the bootloader does not
need to provide a policy to get sane behavior from an XSM-enabled
hypervisor. The policy provided by the bootloader, if present, will
override the built-in policy.
The XSM policy is not moved out of tools because that remains the
primary location for installing and configuring the policy.

Convert the crash_debug option to Kconfig as CONFIG_CRASH_DEBUG. This
was previously togglable on the command line so this adds a message for
users enabling it from the command line to tell them to enable it from
make menuconfig.

Try to use "xen-qemuuser-domid$domid" first, then
"xen-qemuuser-shared" and root if everything else fails.
The uids need to be manually created by the user or, more likely, by the
xen package maintainer.
Expose a device_model_user setting in libxl_domain_build_info, so that
opinionated callers, such as libvirt, can set any user they like. Do not
fall back to root if device_model_user is set. Users can also set
device_model_user by hand in the xl domain config file.
QEMU is going to setuid and setgid to the user ID and the group ID of
the specified user, soon after initialization, before starting to deal
with any guest IO.
To actually secure QEMU when running in Dom0, we need at least to
deprivilege the privcmd and xenstore interfaces, this is just the first
step in that direction.

xen-*-syms cannot actually be booted, so putting it in /boot is a bit
misleading. It also happens to cause a warning from update-grub (so at
least it doesn't end up in grub.cfg)
/usr/lib/debug seems to be a pretty common path for installing such
debug info.

The current base directory /var/xen/dump for domU dumps will be patched
to /var/lib/xen/dump by most distros to follow FHS.
This change does three things:
- change the default from /var/xen/dump to /var/lib/xen/dump
- provide a configure option to avoid patching the source.
- update docs to refer to the new default location

An increasing version and/or release number helps to update existing
packages without --force as in "rpm Uvh --force xen.rpm". Instead its
possible to do "rpm -Fvh *.rpm" to update only already installed
packages.
The usage of --force disables essentials checks such as file conflict
detection. As a result the new xen.rpm may overwrite files owned by
other packages.
With the current way of calculating version-release it is difficult to
get an increasing release number into the spec file. The release is
always zero unless "make make XEN_VENDORVERSION=`date +.%s`" is used,
which has the bad side effect that xen.gz always gets a different
filename every time.
Update mkrpm to recognize PKG_RELEASE=. Its value will be appended to
the Release string. It can be filled with a time stamp, like:
make rpmball PKG_RELEASE="`date +%Y%m%d%H%M%S`"

This was disabled by default in Xen 4.4. Since xend has now been
removed from the tree I don't believe anything is using it.
We need to pass an explicit CONFIG_BLKTAP1=n to qemu-xen-traditional
otherwise it defaults to y and doesn't build.
This patch does all the ground work, the tools/blktap directory will
be removed in the next (*huge*) patch.
Note that this has no impact on blktap2, which is what libxl supports.
blktap1 was only usable via xend which has already been removed.
