Backport fix from master.

Disable non working test case.
Backport Markov functional model fixes from master.

- Remove cap for F (this causes violations of the C^1 property in
  certain cases). Require decreasing call prices for exponential
  extrapolation.
- Fix floor pricing.
- Fix error check in vanilla engine tests, exclude 0.10 strike and
  change strike 0.07 to 0.06 in cap engine test, use correct yield
  and volatility termstructure in cap engine test.

Merge pull request #27 from Nick Glass.

New Actual/365 (No Leap) day counter.
the expression mm*j can in general not be represented as int, therefore
we need to convert each factor to double before multiplying them
handle limit case strike (including displacement) equals zero
fix maturities for tn and sn quotes,
avoid generating too many quotes (and reading undefined array elements),
write 15 and 35 for the number of FRAs and Swaps entering the curve
throughout the code
avoid unsigned int overflow runtime errors. Although the code probably
works on most (or all?) existing platforms without the changes, strictly
spoken there are undefined subexpressions which we eliminate here.
Merge remote-tracking branch 'lballabio/master'
fixed unsigned int conversion (thanks to Peter Caspers)
