Berkeley DB cleanup, remove versions 4.0 ... 4.7.
- Mk/bsd.database.mk rewrite, new default to db5.
- db6 is eligible by default only if installed on the system.
- Bump PORTREVISION of all ports that directly depend on BerkeleyDB or
  where USE_BDB is found in the port's directory
- Patch a few ports such that they will pick up or work with newer
  versions.
- Add UPDATING entry
- Drive-by format fix for pks
- Drop BerkeleyDB option from mail/popular for now, requires more work.
- Exp-run logs linked from the PR below.
- Ports that do not build (IGNORE, BROKEN, etc.) have pro-forma changes
  for new Berkeley DB, but are untested.

NOTE: please read UPDATING and the Wiki page before proceeding!

  bsd.port.mk also handles configure script outside of WRKSRC.

Exp-runs by:    miwi

- Fix build on FreeBSD 10. Apply manual fix as the configure script is
  outside of WRKSRC and the WITH_FBSD10_FIX knob doesn't work in this
  case.
