The Ganeti code style has been stored on the project wiki at:

  https://code.google.com/p/ganeti/wiki/StyleGuide
  https://code.google.com/p/ganeti/wiki/HaskellStyleGuide

This commit combines the two pages into an .rst file with minimal
formatting and language changes. Note that the style guide introduced
in this commit does not fit the code base in a number of ways,
including:

* Some Haskell files have lines longer than 78 characters
* Some Haskell files have trailing whitespace
* Some Python docstring initial sentences lack punctuation at the end

The decision to either change the offending lines to fit the guidelines,
to change the guidelines to fit the codebase or to simply ignore the
discrepancies is left for other commits to solve.

Fix overridable configure directories, namely, --bindir, --sbindir,
and --mandir.

Variables 'bindir', 'sbindir', and 'mandir' are exported from
'configure.ac' to 'Makefile.am'. At first, it would seem to be
possible to do the following:

  MANDIR := $(mandir)
  ...
  mandir = $(versionedsharedir)$(datarootdir)/$(MANDIR)

However, this does not work in the output of 'configure' (i.e., the
'Makefile'), these variables will be reordered:

  mandir = $(versionedsharedir)$(datarootdir)/$(MANDIR)
  ...
  MANDIR := $(mandir)

As a result, 'MANDIR' will capture not the exported value from
'configure.ac' but the 'mandir' defined in the 'Makefile'.

The solution is explicitly export these variables from 'configure.ac'
with different names, namely, 'BINDIR', 'SBINDIR', and 'MANDIR':

  AC_SUBST([BINDIR], $bindir)
  AC_SUBST([SBINDIR], $sbindir)
  AC_SUBST([MANDIR], $mandir)

The rest is just fixing the paths and the symlinks in the 'Makefile'.
