The xenstore header xs.h is producing conflicts with other software[1].
xs is a too short identifier and does not matche the library. Renaming
the headers to xenstore.h and xenstore_lib.h is the easiest way to make
them easy recognizable and prevent furthe problems.

This patch implements the new protocol for handling pv consoles and
emulated serials as described in the document docs/misc/console.txt.
The changes are:
- xenconsoled: do not write the pty under serial in xenstore if
xenconsoled is handling a consolepath;
- xenconsole: implement support for an explicit console type parameter;
the parameter can be "pv", to specify that the user wants to
connect to a pv console, or "serial", to specify that the user wants to
connect to an emulated serial. If the type parameter hasn't been
specified be the user, xenconsole tries to guess which type of console
it has to connect to, defaulting to pv console for pv guests and
emulated serial for hvm guests.
- xenconsole: use the new xenstore paths;
- libxl: rename libxl_console_constype to libxl_console_consback:
constype is used to to specify whether qemu or xenconsoled provides the
backend, so I renamed it to libxl_console_consback to make it more
obvious that we are talking about backends;
- libxl: add a new libxl_console_constype to specify if the console is
an emulated serial or a pv console;
- libxl: support the new xenconsole "type" command line parameter;
- libxl: use the "output" node under console in xenstore to tell qemu
where do we want the output of this pv console to go;
- remove the legacy "serialpath" from xenconsoled altogether

This can just mean we have raced with the bootloader exiting and if we
continue we will likely see the real domain console show up.

Segmentation fault occurs if DOMID isn't specified.
Some check be added to output error message in this situation.

This patch adds a new command line argument to xenconsole to specify
to which console to connect to in case a domain has more than one.

Make sure that tty semantics are active for Solaris ptys, or if they
aren't (and not needed) to not do tcget/setattr on the filedescriptor
in Python code.
Also work around a bug in the Solaris ptm streams driver, which will
cause a write error on the master side of a pty (because of e.g. a
missing slave) to persist forever.

- xend forwards console traffic between the running bootloader and a pty
which it writes to the store so the xenconsole client can see it.
- the xenconsole client handles the domain's console pty changing.
- xm create no longer runs the bootloader.
- pygrub gets '-i' option to explicitly request an interactive session.
- xend unlocks the domain list during bootloading so that "xm console"
can see the domain and attach to its console pty.

the intention appears to have been 500msec, but struct timeval when used with
a select() is in usec, not msec. The timeout has been set to 250msec (500msec
seems a little long, in any case).

through to the store daemon and get rid of the nasty serialisation
mutex for transactions.

There is a race condition that occurs after xend creates a domain.
The console client might be running before the console daemon has
noticed the new domain and setup a pty for it.
