Handle netdev secondary addresses and labels
Fix the network-bridge logic to correctly transfer secondary IP
address from $netdev to $bridge.
e.g. if you add an secondary address/label/alias with:
$> ip addr add 172.31.0.200/24 dev eth0 label eth0:00
then, "ip addr show dev eth0" gives e.g.:
inet 172.31.0.10/24 brd 172.31.0.255 scope global eth0
inet 172.31.0.200/24 scope global secondary eth0:00

ip addr add 172.31.0.10/24 brd 172.31.0.255 scope global dev tmpbridge
ip addr add 172.31.0.200/24 scope global secondary dev tmpbridge:00
which causes the sript to fail because:
1) The device tmpbridge:00 doesn't exist
2) The "secondary" flag isn't valid
This patch fixes the sed commands to instead give:
ip addr add 172.31.0.10/24 brd 172.31.0.255 scope global dev tmpbridge label tmpbridge

linux: Force build failure if modules build fails
When building a linux kernel, if the modules build fails, then
the build carries on regardless.
The problem is simple - the "make modules" failure is not seen
by the calling make since its return value is not what is
returned.

hvm: Fix TPMD and QEMU connection
In HVM domain, MA_Transmit function in tcgbios sometimes become an

function.
Before the MA_Transmit function was called, the attached patch
corrected so that connection of QEMU and TPMD might be completed.

tools/examples/block better use of losetup -r
Use losetup -r when the vbd is specified to be readonly, but only if
-r is supported (rather than always creating a writeable losetup
mapping if possible).
This was inspired by (but not derived from) a diff from the Fedora 8
patchset which uses -r iff the vbd is specified as readonly. We need
to be cleverer upstream because not all systems have losetup -r.

Fix master/slave handling in xenconsoled and qemu
Fix a number of problems with the pty handling:
- make openpty() implementation work on Solaris
- set raw on the slave fd, not the master, as the master doesn't
have a line discipline pushed on Solaris
- make sure we don't leak the slave fd returned from openpty()
- don't use the 'name' argument of openpty() as it's a security risk
- note behaviour of a zero read of the master on Solaris
- remove pointless tcget/setattr

[IA64] xenoprof: various fix on linux-xen/perfmon.c
Various fixes on xen/arch/ia64/linux-xen/perfmon.c
- Fix starting/stopping sampling.
So far IPI is used. but psr.pp isn't preserved when nested interrupt case
with VTi domain. Instead timer is used.
- Redefines ia64_set_pmc() to enable sampling of all xen VMM/guest
kernel/guest user process. It supports only generic pmc/pmd.
- Twist xenpfm_write_pmcs()
It is also used when turning on pmcs. So bailing out when error is not
appropriate. Even when error occures, it should continue to update next
cpu's pmcs.
- Add gdprintk(XENLOG_DEUBG) and BUG_ON()s.
