When an OpCode's parameter has a tuple as default value, this code
will break:

  buf.write("defaults to ``%s``" % default)

The patch fixes this and other potential cases by always passing a
tuple to '%'.

Currently the man page build rule is run without ‘-e’, so the actual

Additionally, check-man-dashes is now verbose, otherwise it's hard to

breaks the source code viewing for all the others.

The patch replaces this with automatic building; as playing with
relative symlinks is non-trivial, I just generate it many times (the
file is small enough (<250) that it shouldn't matter, size-wise, and
it takes 2ms to do it).

This patch does multiple enhancements to the way we build the Haddock
docs, motivated by the fact that if we don't run Haddock over test
files as well, bad formatting can be submitted and will accumulate
over time (without any checks).

The patch does:

- replace manual built ALL_APIDOC_HS_DIRS with automatically built one
  (from HS_DIRS)
- change Haddock so that it runs from the top directory (instead of
  from src/)
- change HsColour target file to be built via bash parameter
  substitution, rather than sed (I don't know how to do it in one go,
  so I use 2 intermediate variables)
- change 'hs-apidoc' target so that it depends on the real target
  file; in case no source file has been modified, running 'make
  hs-apidoc' twice will not result in two runs
- run HsColour/Haddock under en_US.UTF-8 locale, otherwise they can't
  parse correctly the Unicode chars in the test files

Additionally, wrong formatting (oops) in a test file has been
corrected.

When file storage is disabled at ./configure time, we shouldn't pass
opcodes containing DTFile/DTSharedFile/StorageFile to Python for
validation, as they will fail.

This patch implements this by simply tweaking the Arbitrary instances
for DiskTemplate and StorageType (which IMHO is a nice and clean
way!), and also fixing the generation of arbitrary IPolicies to use
the correct 'allDiskTemplates' list (otherwise we'd loop forever
trying to generate a list of all templates).

It turns out that, in Python, booleans are also integers. So they fall
under the “isinstance(value, int)” case, resulting in all enable*
constants being integers in Haskell, which is not nice, even though
we're not using them directly today.

Currently, the iallocator interface requires LVM storage, due to the
way it computes the node storage information.

By changing the code to understand that GetVGName() can return None,
and by setting the disk_total/disk_free node parameters to the value
zero, we can workaround this issue until proper multi-storage
reporting is implemented.

The hail iallocator plugin works without changes once this is
implemented, as it already handles non-LVM storage as "foreign"
storage (with unlimited capacity).

The patch also changes a bit how the parameters are retrieved and
used; hopefully this is a bit safer and more readable.

'MakeLegacyNodeInfo' is not the best place for this, but we'd have to
duplicate it if we wanted a LVM-less version, so the easiest is to add
an optional parameter that allows it to accept/skip LVM-less results.

It still requires at most one VG result, so its behaviour isn't
changed in this respect.
