directql does not work with input files

[Veranika Liaukevich]

directql returns empty results for queries with input files:

$ directql -q 'select sdom(decode($1))' -f ~/Pictures/aok.png --out string
directql: rasdaman query tool v1.0, rasdaman v9.0.5-gffe716e -- generated on 04.11.2014 15:19:10.

Insert and update queries which use files and are sent via directql does not affect data.

directql -q 'insert into rgb values decode($1)' -f ~/Pictures/aok.png --out string --user rasadmin --passwd rasadmin

directql -q 'update rgb set rgb[0:1,0:1] values decode($1)[0:1, 0:1]' -f ~/Pictures/aok.png --out string --user rasadmin --passwd rasadmin

Common code from rasql and directql should be refactored in a class in raslib, so we avoid duplication.

[Dimitar Misev]

So the common code should be put in raslib/clientsutil.cc

rasql should be considered as having the most recent bug-fixed code, as directql hasn't been used so much.
