- added the s6_fdholder library to libs6. (Nothing useful yet.)
- fixed execline invocation in s6-log with slashpackage - integrated s6_svc_main.c's functionality into s6-svscanctl and deleted it - integrated Olivier Brunel's suggestions for wstat report in supervise/status - minor fixes to s6-supervise's status reports - separated sigaction calls in ftrigw_notifyb, this spares a few syscalls in s6-supervise - updated doc to reflect the changes - version bumped to 2.1.0.0 because API breakage (./finish, s6-svstat)
