This patch changes the blktap code mapping pages to user space to be
faster and to allow page lookups to foreign mapped pages through linux
to do direct io. An AIO test driver on this achieves comparable
performance to the in-kernel block-backend.

and changes xm to simply exec /usr/libexec/xen/xc_console.
I've done a pretty good amount of testing and this seems to clear up all
of the Xend console issues in bugzilla.
This is a pretty big change to Xend though with a lot of deleted code so
I'd appreciate if people more familiar with the Xend codebase could look
through it critically.
In addition to the patch, the following files are no longer used:
tools/python/xen/util/console_client.py
tools/python/xen/xend/XendConsole.py
tools/python/xen/xend/server/SrvConsole.py
tools/python/xen/xend/server/SrvConsoleDir.py

There are several people I am aware of interested in writing non-GPL
tools, and this code is trivial, so they'd just end up writing their
own.

explicitly specifies a 'com1=' or 'com2=' configuration
string. This prevents users from being surprised when Xen
stops domain0 from accessing serial port registers.
On ia64 we still allow serial ports to get automatically
configured and locked down even if no 'com1' is specified
on the command line. This maintains the default preferred
by the IA64 developers.
Also, the method for specifying 'use existing baud rate'
has changed. Instead of specifying com1=0, you must now
specify e.g., com1=auto

allows them to be used in situations where the IRQ subsystem is
not paravirtualised.

2) Fix memory leak in domain free
3) Fix error path in read (reported by aq)
4) Move reading of buffer limit to tty reconnect so that changes in
limit take affect more quickly.

Requires permission check every time event is generated.
Requires generalization of permissions: ask arbitrary number of
parents whether it's OK to tell about node (eg. watching
/dir/subdir/x when /dir is deleted: root permissions will now
determine whether we fire event).
Add test that we don't leak information on whether a file exists
or not.
