  raster module memory: set new value globally (#922)

* raster module memory: set other value globally

This change allows to globally override the default 300 MB with a user defined value:

r.in.gdal --help
Imports raster data into a GRASS raster map using GDAL library.

Usage:
 r.in.gdal [-ojeflakcrp] input=name output=name
...
Parameters:
           input   Name of raster file to be imported
          output   Name for output raster map
            band   Band(s) to select (default is all bands)
          memory   Maximum memory to be used (in MB)
                   default: 300
          target   Name of GCPs target location
           title   Title for resultant raster map
          offset   Offset to be added to band numbers
                   default: 0

g.gisenv set="MEMORYMB=6000"

r.in.gdal --help
Imports raster data into a GRASS raster map using GDAL library.

Usage:
 r.in.gdal [-ojeflakcrp] input=name output=name
...
Parameters:
           input   Name of raster file to be imported
          output   Name for output raster map
            band   Band(s) to select (default is all bands)
          memory   Maximum memory to be used (in MB)
                   default: 6000
          target   Name of GCPs target location
           title   Title for resultant raster map
          offset   Offset to be added to band numbers
                   default: 0

g.gisenv set="MEMORYMB=300"

Based upon demo patch my @metzm

* fix double description

* code simplification by defining new G_define_standard_option(G_OPT_MEMORYMB)

* update STD_OPT_STRINGS after include/gis.h modification

* Patch added to also set default answer at compile time

* document new GRASS variable MEMORYMB

- fixes the creation of man pages
