Updated security/keychain to 2.6.6

* keychain 2.6.6 (08 Sep 2006)

  08 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Make --lockwait -1 mean forever.  Previously 0 meant forever but was
  undocumented.  Add more locking regression tests #137981

* keychain 2.6.5 (08 Sep 2006)

  08 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Break out of loop when empty lockfile can't be removed #127471.  Add locking
  regression tests:
    100_lock_stale 101_lock_held 102_lock_empty 103_lock_empty_cant_remove

* keychain 2.6.4 (08 Sep 2006)

  08 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Add validinherit function so that validity of SSH_AUTH_SOCK and friends can be
  validated from startagent rather than up front.  The advantage is that warning
  messages aren't emitted unnecessarily when --inherit *-once.
  Fix --eval for fish, and add new testcases:
    053_start_with_--eval_ksh
    054_start_with_--eval_fish
    055_start_with_--eval_csh

* keychain 2.6.3 (07 Sep 2006)

  07 Sep 2006; Aron Griffis <agriffis@gentoo.org>:
  Support fish: http://roo.no-ip.org/fish/
  Thanks to Ilkka Poutanen for the patch.
