[cups.bugs] [HIGH] STR #1559: fd handling issues in start_job...

[jlovell.apple]

[STR New]

There seems to be two fd handling issues in start_job:

- status fds need to be kept in cupsd_job_t since they are reused in
multi-document jobs (and 'statusfds[1]' should only be closed after
starting the last document).

- 'filterfds[slot]' should only be closed after starting the last document
since they are copies of 'job->print_pipes'

These bugs manifest themselves by eventually causing select() to return
EBADF.

This code is slightly tricky... I believe the attached patch is correct
but please check.

Thanks!
