Log Message:
Update to 0.9.6.1.

Changes:

* libprelude-0.9.6.1:

- Flex generated file build fix for FreeBSD / NetBSD.

* libprelude-0.9.6:

- Implement workaround for buggy libtool that will fail
  looking up symbol with preopening enabled in case the
  libtool archive is missing. Lot of distribution package
  seem to suffer from this.

- idmef-path API improvement, allow user to specify negative
  index to address the list in reverse. Developer are now
  supposed to use IDMEF_LIST_APPEND (in place of index -1) and
  IDMEF_LIST_PREPEND (in place of 0) on listed object operation.

- idmef-path API improvement: support for (<<) and (>>) listed
  object index, meaning to prepend the object / to append it,
  as well as (*) meaning to retrieve all object from a list. This
  deprecate the usage of (-1) previously used for appending.

- Fix deconnection problem in client reading mode.

- Improve option parsing: option value can now be provided using
  --option=value. This format is now a requirement for option that
  use an optional argument. Provide arguments information in the
  option help.

- Fix deadlock on asynchronous prelude-client destruction.

- Definitely fix the problem where prelude-adduser will, on some system,
  listen to Ipv6 IP address as the default: we now bind every address
  returned by getaddrinfo().

- Fix crash in case of successive call to prelude_init(), prelude_deinit(),
  then prelude_init() again.

- Introduce --passwd and --passwd-file option for prelude-adduser
  register and registration-server mode, allowing to specify one shot
  password on the command line, from a file, or from stdin.

- Verbose error handling for prelude-adduser.

- Fix perl bindings, make them more robust by adding type checking, and fix
  memory leak.

- Fix parsing of string based broken down time criterion.

- Handle configuration file containing \r.

- Fix prelude_read_multiline2() return value (fix Prelude-Manager
  idmef-criteria-filter plugin).

- Fix a bug in per thread error handling code which resulted in NULL
  error to be returned in case an application thread exited.

- Various bug fixes.
