RANK: Adopt a new ranking implementation.
Before this commit, the implementation of RANK made multiple passes
through the active file, opening and closing it (with proc_open()
and proc_commit()) as many times as there were input variables.
This worked in simple cases, but it could never work with
TEMPORARY since the second proc_open() will see a different set
of data from the first one.
This commit rewrites RANK to open and read the active file only
once. It does not make RANK properly work with TEMPORARY, but
it brings it much closer. It may also be faster in some cases
because, although it makes the same number of passes through
the input data (necessarily), each pass discards all the input
columns except the ones that are really need for that pass.

RANK: Create all variables together, in order.
An upcoming commit will rewrite the RANK implementation so that the
new variables are not created until after a pass through the data.
(This makes sense because their values cannot actually be determined
until that pass is complete, so there is no point in allocating space
for them in cases.) To do that, it is necessary to figure out the
variable names (and that they will be valid variable names) in
advance. This commit switches to that approach in advance.
This approach has another small advantage: the order of the variables
added by RANK to the dictionary does not depend on whether the
variables are named by the user or by generating a name. (This
is why the rank.at test case changes.)

transformations: Relax the rules for transformation finalizing.
The trns_chain data structure has a barely useful concept called
"finalization". In practice this is used to make sure that control
structures (e.g. DO IF) that are opened get closed (e.g. END IF). There
are currently some restrictions on finalizing: namely, transformations
can't be added after a chain is finalized. Since finalizers are barely
used, we can relax this restriction, which this commit does. This will be
used in an upcoming commit where the ability to add a transformation to a
finalized change becomes useful for a corner case.

Remove assertions which compare the sum of weights between passes.
These asserted that the sum of case-weights of a dataset calculated
in one pass, was the same as that calculated in a second pass.
Algebraically this is correct. However, for optimisation purposes,
it is sometimes desireable that the second pass occurs after the
data has been reordered. If that happens, the sum of weights can
be slightly different due to floating point rounding errors. This
happens particularly when the caseweights are fractional.

This function used *printf with a %f directive, which under certain
