The emacs variable to set the C style from a local variable block is

NetBSD libxc hypercall implementation was returning -errno on error,
instead of the actual error value from ioctl. Returning error is
easier to understand, and the caller can always check errno.

Move (page aligned) buffer allocations in {os}_privcmd_alloc_hypercall_buffer
into a global function xc_memalign. This API is also used by Remus
compression code to allocate compression caches that need to be page aligned.

It's not clear why a userspace lzma decode would want to use that
particular value, what bearing it has on anything or why it would
assume it could use 1/3 of the total RAM in the system (potentially
quite a large amount of RAM) as opposed to any other limit number.
Instead, hardcode 32Mby.
This reverts 22830:c80960244942, removes the xc_get_physmem/physmem
function entirely, and replaces the expression at the call site with a
fixed constant.

NetBSD doesn't have sysconf(_SC_PHYS_PAGES).
Factor physmem() out into os-dependent files and rename it to
xc_get_physmem() so as not to pollute the namespace.

Attached patch makes libxc build again on NetBSD after the recent rework.
[ Modified by iwj:
I changed the name of the new make variable from LIBDL to DLOPEN_LIBS.
The latter conforms to the naming scheme for similar variables found
in config/*.mk - PTHREAD_LIBS et al.
Also I moved the setting of the variable to -dl from Linux to StdGNU
(which makes it apply more widely) and also added it to SunOS.mk
(based on pure guesswork). ]

i.e. not running on a real hypervisor
Allows users of the library to adjust behaviour. I don't especially
like this violation of the abstraction but both oxenstored and xapi
use this to avoid difficult to simulate operations when running on the
simulator.

This makes the interface consistent with the changes made to the main
interface in 21483:779c0ef9682c.
Also fix some references to "struct xc_interface" which should have
been simply "xc_interface" in tools/xenpaging, and update QEMU_TAG to
pull in the corresponding qemu change.

Doesn't actually appear to be used anywhere but is defined for other
OSes.
The NetBSD evtchn.h contains comments "Return allocated port" for
several ioctls which currently return the allocated port as a member
of the argument structure and not as the ioctl return value (I think
this is a cut and paste error).

tools/libxc, tools/libelf: Relicense under LGPL v2.1
Relicense these two libraries under LGPL v2.1 only except where
individual files already included the "or later" provision.
Copyright holders have been contacted by Stephen Spector and have all
agreed this change.
Removed tools/libxc/ia64/aclinux.h since it appeared to be
unused. There is a separate, more up to date, copy in
xen/include/acpi/platform/aclinux.h which does appear to be used.
Clarify the license of MiniOS privcmd.h under the same terms as other
tools/include/xen-sys headers.

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.
