databases/cego,devel/lfcbase: update 2.52.4 -> 2.52.6, 1.21.6 -> 1.21.7

lfcbase:

• Added improvements to Pager class, e.g. case insensitive search and message box at end of search

cego:

• Small adaptions made for Debian ( in cgwtest.c, cast added to malloc for CGClob and CGBlob allocation ). There are still required some changes for the testsuite shell scripts to satisfy Debian flavour ( expimpcheck )
• Patch added in CegoCondition and CegoPredicate for arithmetic expression evaluation. The recent grammar modification limits enclosed arithmetic expression to logic expressions. This leads confusing results e.g. for select ( a + b ) / 2 from t1 since ( a + b ) is evaluated as a condition with a logical value as the result ( true or false ) ( caused by grammar production : Factor -> LB Condition RB ) Arithmetic expressions are just parsed with grammar production Predicate -> Expr ( expression only ), so for this case now a special handling has been added ( with new introduced method CegoPredicate::getExprOnlyValue )
