tools/xend: Fix performance of xend with more than 10000 FC device paths
On server startup xend start or a later xend restart needs approx. 30 min to
start/restart. Without attached FC devices xend start/restart needs only some
seconds.
server type: Fujitsu Primergy RX600-S5
The time gets lost in xen/xend/XendNode.py line 329 while calling
vscsi_util.get_all_scsi_device().
329 for pscsi_record in vscsi_util.get_all_scsi_devices():
330 scsi_id = pscsi_record['scsi_id']
331 if scsi_id:

I think, in most cases we don't need all the PSCSI devices registered in
xend, but only a few of it.
So a good solution for this perforamce issue is to scan only the SCSI device
paths we need, controlled by a new option in xend-config.sxp.
I have made a patch to allow specification of scsi devices we need in xend
in the config file xend-config.sxp.
The new options pscsi-device-mask expects a list of device ids oder partial
device ids like the option of lsscsi, e.g.
(pscsi-device-mask ('<partial-dev-id1' 'partial-dev-id2' ...))
Without this option set in xend-config.sxp or if lsscsi is not support, all
device paths are process like today.

libxl: consistent handling of libxc errors
Lots of places in libxl return -1 as an error which is inconsistent with
libxl error codes since that is ERROR_VERSION. Also in other places the
xc_* function to implement a command is called but the return value is
either never checked or not passed on.
This patch makes callers of libxc functions use XL_LOG_ERRNO to log a
suitable message including the contents of errno, before returning
ERROR_FAIL, if an xc call fails. (Except for pci device removals and
domain destroys where release of resources ought to continue even if
an error occurs in an early step. In this case the error is still
logged at least.)
Also a bug is fixed where a caller depends on errno being set but is
cleared by cleanup code which calls in to library functions which modify
errno as a side-effect.
This is version 2 of the patch previously applied as
91c486918e02.
Changed since then: Removed mapping from libxc error codes to libxl -
this is redundant because libxl ought to return -1 with errno set to a
meaningful value.

I'm afraid this pattern is wrong for two reasons. Firstly,
xc_domain_pause and functions like it do not return XC_ERROR_* values.
They typically return -1 on error, and set errno.
Secondly, the error codes from libxc are not really all that useful.
They mostly serve to identify where the error originated.

stubdom: correct handling DESTDIR during build
The stubdom/Makefile expects components to install themselves to
stubdom/$(CROSS_ROOT) and passes the appropriate configure and make
variables to make this happen.
However if the top-level build uses DESTDIR then this not only effects
the installation targets in stubdom/Makefile but is also propagated to
the individual components' build causing them to install into an
unexpected location and breaking the build.
In other words "make -C stubdom DESTDIR=/tmp/a-dest-dir" fails due to missing
headers because they had been installed into /tmp/a-dest-dir instead of
stubdom/$(CROSS_ROOT).
The existing attempt to clear DESTDIR for the newlib install phase was
insufficient.
Define a CROSS_MAKE variable which should be used to recurse into the
cross compiled components and which clears DESTDIR.
Also move the definition of the genpath target to after the first
"all" target so that the default target is all.
I have confirmed that with this fix only the Xen build system outputs end up in
/tmp/a-dest-dir.

x86: optimize this_cpu()
Besides the .text space savings of over 2.5k on x86-64 (1.5k for

frequently executed code paths, and finally provides a reason (other
