Add/Android: Provide geo coordinates for clicked position in contextual menu (#794)

* Adding unescape string utility and unescaping alls values in textfile attributes
* Moving coordinates_geo out of internal use in gui_internal_command.c (to coord.c)
* Moving gui_internal_escape() into generic str_escape() function in util.c
* Moving strncpy_unescape() into generic function in util.c
* Using geo coords as item name in Android contextual menu "Route Here"
* Using string escaping (for double quotes) when writing former destinations to file
* Adding new type DEGREES_MINUTES_SECONDS_BRIEF to factorize coordinates_geo()
And fixing the example strings to match what is actually output by the function
* Adding support for DEGREES_MINUTES_SECONDS_BRIEF format into coord_format
And add internal coord_format_with_sep() to specify the separator
* Fixing doxygen doc for coord_format_with_sep()
* Making coord_format() inline
* Using new factorized generic function coord_geo_format_short() instead of coordinates_geo()
* Changing single contextual window title with GPS coords on Android
* Adding string bytes length for each coord to string format, using short format in pcoord_format_short() and coord_geo_format_short()
* Using pcoord_format_short() in android
