#2943: Absolute path in TGIS connection can make db inaccessible in a (mixed)
multi-user environment

 It seems that the connection to the TGIS sqlite.db is defined for the
 mapset using an absolute paths.

 That makes it inaccessible in cases where mount points change, e.g. in a
 multi-user environment. In my particular case,
 /grassdata/ETRS_33N/precipitation_daily/tgis/sqlite.db (produced from
 within Linux) is (naturally) not readable from Windows where the
 equivalent path would be
 R:\grassdata\ETRS_33N\precipitation_daily\tgis\sqlite.db

 One can work around this issue using t.connect -d when starting to work,
 but this is only possible for "mapset owners".

 Would be nice if environment variables could be used
 ($GISDBASE/$LOCATION_NAME/$MAPSET) and first expand/evaluate at access
 time or relative path to the current mapset...
