since img in that case was actually the image and the coils together.
It now reflects standard usage: x is the variable optimized by the
IRGNM.

The irgnm can now take a callback.

nlinv can now calculate how long the reconstruction took

The code now also outputs the sensitivites calculted by nlinv when run
on the GPU. This is possible by excplicitly copying data.

this is needed when usinc virtual-conjugate coils, for example

This commit adds ENLIVE to the exisiting nlinv code.

ENLIVE is a method for allowing multiple sets of images and coil
sensitivity maps in the reconstruction, similar to multiple ESPIRiT
maps.

Commit 2d31b70b removed most water/fat
code from nlinv. Relics were the sign_dims in model.c and the
CSHIFT_FLAG. This commit removes those, too.
