/trunk

SQL cleanup:

  • Made liberal use of "<<=" operator and "where" for DBMS-layer CIDR comparisons
  • Made liberal use of "select count(*) from ... where ..." in place of much more cumbersome "select * from ..." constructs

General code cleanup:

  • Better SQL allowed removal of a number of "if $cidr->contains($block)" constructs
  • Removed some unnecessary code originally added to fit existing legacy code
  • Cleaned up comments (indenation consistency, notes on DB fields)
  • Added a few ##fixme tags where the intended function and execution aren't clear, or don't quite work correctly in some odd edge cases
  • Moved %allocated, %free, %routed, %bigfree hashes to IPDB.pm as globals
  • Property svn:executable set to *
  • Property svn:keywords set to Date Rev Author
