The following changes are made:
 * Add M4 as required dependency
 * Change reference to qemu-img package to qemu-utils
 * Never use `sudo` for easy_install (not used for apt-get neither)
 * Add libpcre3-dev as required package for Wheezy (otherwise linking
   fails)
 * Install sphinx from packages (easy_install would install an
   incompatible version on Wheezy)
 * Fix spelling error

From version 2.11 onwards, the default for Ganeti is to install as
a standby version to be activated by the old Ganeti version itself.
While this is useful for existing users, first-time installations
need to add these symlinks or configure with ``--enable-symlinks``.
Add this information to the INSTALL instructions.

As queryd will, in the future, handle all LUXI request, queue jobs and

The tests are already using this library, so it's not really a new build
dependency, but it was not specified esplicitly.

Furthermore, it's going to be used by the instance status collector, so it's

Currently, we support curl being optional via some sporting exercises:
ifdefs in the code, data types that represent 'Curl is disabled'
state, etc. However, with the future work on RPC, we would have to
even make the dependencies list conditional on it, etc. This is too
much work, when the curl library is included even in stable
distributions.

This patch changes curl from option to required, the same as the other
base libraries.

This patch cleans up  the Haskell library detection and defaults.

First, it makes the base compiler/libraries required, per the email discussion.

It then adds two new small autoconf macros, on to check for a required
Haskell library and one to do custom action based on test results. We
use these macros to cleanup and simplify a bit the module detection:

- rapi, confd, and split query are auto detected and enabled if _all_
  required libraries are present
- unittests are enabled if _all_ required libraries are present

The patch also updates the documentation regarding required libraries.

After this patch, base Ganeti fully buildable on Debian Squeeze/Ubuntu
Lucid.

This adds basic infrastructure for filtering (fully functional except,
as usual, for runtime data), and then uses it for node queries.

Since the filtering exports regex matching as an external
functionality, we have to use a regex library. There are many flavours
of these in Haskell (see
http://www.haskell.org/haskellwiki/Regular_expressions), but since we
want to be as compatible as we can with Python's, we use the
regex-pcre one, which is a wrapper to the widely used 'pcre' library.

I'm doing this change for future performance optimisations. Currently
we use the Luxi interface just as a client, so not in the hot path,
but when we'll use this as a server interface, we're interested to
both reduce the space and time consumption of the interface.

We have to simultaneous changes here:

- switch from using socket-related function (sendto, recv, etc.) to
  handle-based functions, since the standard network library doesn't
  work with sockets
- switch from using Strings for the internal buffer to strict
  ByteStrings; the only downside is that we now have the issue of
  decoding/encoding from binary to UTF-8 strings, a fact which brings
  its own issues into the mix (we have to check for failed decodings,
  etc.); but this is similar to what we'll have to handle on the
  Python side when moving to Python 3.x
