Update to 1.4.20:

Overview

Just one tiny change to fix a regression causing threads to lock
up and spin max CPU.

1.4.18 and 1.4.19 were affected. 1.4.17 and earlier were not
affected. If you are on .18 or .19 an upgrade to 1.4.20 is strongly
advised.

Thanks to commando.io for reporting the bug initially and putting
up with me being blind for a few weeks.

Fixes

Fix a race condition causing new connections to appear closed,
causing an inifinte loop.
Updated devel/memcached to 1.4.20
Haiku also has getprogname(3)/setprogname(3).

Haiku has groupadd now.

While here, enable useradd only for the case groupadd exists,
because former useradd is interactive command, not usable with pkgsrc framework.

Changes 1.10.0:
* VIGRA got a tutorial.
* Significant simplification of the API: MultiArrayView arguments can now be passed to functions directly. The old syntax with Argument Object Factories (srcImageRange(), srcMultiArray() and relatives) remains valid, but is only required when the arguments are old-style BasicImages.
* Made StridedArrayTag the default for vigra::MultiArrayView .
* Added an efficient multi-dimensional vigra::GridGraph class which support both the LEMON and boost::graph APIs.
* Generalized various algorithms to arbitrary dimensions (gaussianGradientMultiArray(), hessianOfGaussianMultiArray(), gaussianDivergenceMultiArray(), localMinima(), localMaxima(), labelMultiArray(), watershedsMultiArray()).
* Added slicSuperpixels() for arbitrary dimensions.
* Added automatic differentiation (see vigra::autodiff::DualVector).
* Added nonlinearLeastSquares() using the Levenberg-Marquardt algorithm and automatic differentiation. More information about the changes can be found on the changelog page.
