Cleanup: move parse_location() declaration into header file

Browse source 
The parse_location() function was used in three places. In two
of them, the declaration was in the translation unit. Instead,
move the declaration into a header file, to avoid duplication
and the possibility of inconsistencies.

The "units.h" header was chosen as this is where location_t
is defined.

Moreover, make the string argument to parse_location() "const
char *", so that it can be used on non-owned buffers.
