Gnuastro's memory mapping is now a local variable

As described in the commens above `MINMAPSIZE' of `LOCAL.mk.in', the amount
of memory to map to HDD/SSD or keep in RAM is a local issue and not
relevant to the pipeline's results. So it is now defined in a
`gnuastro-local.conf' file.

To keep the Makefiles clean, this file is created by the `./configure'
script. To do this cleanly, the `./configure' script was also almost fully
re-written with better functionality now.
