smurf: Add SMO smoothing model to iterative map-maker
SMO == smoothing model
Add boxcar smoothing via smf_boxcar1D.
Not really tested and bound to have problems with quality flags.

smurf: Check the bits in PLN and not multiply them
One of the if clauses checked the return result of multiplying
a quality with a bit rather than checking the logical AND.

smurf: Assigning a negative number to a size_t does not work
"off" was a size_t so in this code below:
if( i < (window-1) ) off = -i/2;
else off = -window/2;
"off" was becoming very large and walking off the end of the array. I
have no real idea how boxcar smoothing was even working. "off" is
now a long and the above code changed to:
if( i < (window-1) ) off = -1*(long)i/2;
else off = -1*(long)window/2;

smurf: some test code for alternative sample variance calc in maps
Per was looking into how the map sample variance is calculated. In
order to do his version we need to keep track of an additional sum,
the total of the mapweights^2 which requires an additional map-sized
buffer in smf_iteratemap and an extra parameter to smf_rebinmap1. To
turn this alternative method on, uncomment the line at the top of
smf_rebinmap1 that defines __SMF_REBINMAP__SAMPLE_STANDARD_DEVIATION.

smurf: clean up needlessly complicated init in smf_model_create

smurf: heavier clipping when finding RMS gradient in dc step correction
Clip at 2 sigma (not 3) when finding the RMS gradient, and
then correct for the heavy clipping using the factor appropriate
for pure Gaussian noise. heavier clipping does better in the
presence of lots of steps.

smurf: Fix bad quality indexing in step correction
This looks better... Fix a problem indexing the quality array when steps
are found close to the start or end of the time series.

Revert "smurf: Correct indexing of quality array when DC steps found close
to start or end"
This reverts commit fca589ac61bcbe47872c07c529e9fc18b3e58871, which was
done in a rush prior to going on holiday and seems to break things.

smurf: Ignore previously flagged jumps when fitting data to a new jumps
Previously, the least squares fits that are used to determine the data
levels before and after a correlated DC step were including data that had
previously been flagged as a jump (i.e. the samples where the DC level is
moving from the lower level to the higher level). This could cause some
steps that have previously been fixed to be re-introduced (with a
different step height).
