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.

+# Memory mapping minimum size
+# ---------------------------
+#
+# Some programs (for example Gnuastro) can deal with cases where the local
+# system doesn't have enough memory (RAM) to keep large files there. For
+# example, they will create memory-mapped (`mmap' for short) files on the
+# HDD or SSD and read/write to them instead of RAM. This will ofcourse,
+# slow down the processing, but atleast the program won't crash.
+#
+# Since the memory requirements of different systems are different and it
+# has no effect on the software's final result, the minimum size of an
+# allocated array to warrant a mapping to HDD/SSD instead of RAM must also
+# be defined here. This value will be used in the programs that support
+# this feature.
