devel/lfcbase,databases/cego: update 1.21.8 -> 1.22.1, 2.52.19 -> 2.52.20

lfcbase:
- Fixed BigDecimal class for internal constructor to
  normalize zero values to "0" and in scaleTo method to treat
  zero values correctly
- Added class Replacer to support string replacement based
  on regular expressions ( like unix sed )
- Fixed BigDecimal, scale handling still not correct for some cases
- Replacer: The match token has been changed to $ char to treat
  database integration

cego:
- Performance optimization added in CegoSelect and CegoDistCursor
  for or-condition handling:
  If an or-condition is recognized, the predicate is propagateed
  to the corresponding join level cursor and the evaluation is handled
  by the cursor.
  This can avoid large table cursor result sets for the embedding
  join and might improve overall performance of the query.
- For the new introduced query optimization, several code extensions
  have been added. In CegoPredicate, new methods map, getReduced,
  mapExpr and reduceExpr have been added to convert the "master"
  predicate to an appropriate form, which can be handled by CegoDistCursor.
  Also for for CegoDistCursor, the distSetup methods have been expanded
  to propagate the master predicate
- Added fix in CegoAction for the following query:
  select invid from invoice where status = ( select 'OPEN' );
  In CegoAction::noFromOption, for _coListStack has to be pushed empty coList
- Added verify010 db check with a small invoice er model. This is
  used for advanced query verification with multilevel nested views
  and other dynamic stuff which is also relevant to proof valid results
  from query cache
