- Split code using ctypes directly into a helper class
- Don't load “libc.so.6”, but use handle for main program instead (see
  comment in code)
- Clarify comment on errno with older ctypes versions
- Rename unittest since it can't be used for other functions (modifies
  process environment at runtime)
- Add boolean return value for “Mlockall”

These changes are leftovers from some experiments with ctypes.

The “constants” module is a bit special in the sense that we don't want

We currently use 'filter' as the OpCode, QueryRequest and RAPI field
name for representing a query filter. However, since 'filter' is a
built-in function, we actually have to use filter_ throughout the code
in order to not override the built-in function.

This patch simply goes and does a global sed over the code. Due to the
fact that the RAPI interface already exposed this field, we add
compatibility code for now which handles both forms.

If a cluster has any non-master-candidate nodes, those don't contain all
files (e.g. config.data). With commit aef59ae7 (March 31st, 2011)
the logic was changed and subsequently verifying a cluster with non-mc
nodes would complain.

This patch fixes this issue by changing the algorithm. It also adds an
additional check for files which shouldn't exist on a machine. A newly
added unittest is included.

When verifying a group the code would always check SSH to all nodes in
the same group, as well as the first node for every other group. On big
clusters this can cause issues since many nodes will try to connect to
the first node of another group at the same time. This patch changes the
algorithm to choose a different node every time.

A unittest for the selection algorithm is included.

JSON only supports a very restricted set of types for dictionary keys,
among them strings, booleans and “null”. Integers and floats are
converted to strings. Since this can cause a lot of confusion in Python,
this check raises an exception if a caller tries to use such types.

Since the pre-Python 2.6 “simplejson” module doesn't support overriding
the function where the conversion takes place this check can only be
done for the newer “json” module.
