Refactor btree recursive traversal code

Previous releases had a nonstandard entry point (bt_rseq) into libdb2
to perform recursive traversal of a btree database that might be
corrupt so that an operator could attempt data recovery.  This entry
point became inaccessible to user commands after krb5-1.5 due to
integration of the DAL.

Refactor the recursive traversal code into the existing btree
sequential traversal code, accepting new movement flags R_RNEXT
(recursively advance to next item) and R_RPREV.

Add commands to the libdb2 btree test program bttest to exercise this
functionality.  Fix up the existing "rlist" command of bttest to use
the updated interface.
