Ron Yorston a1b0d3856d ash: add process substitution in bash-compatibility mode
Process substitution is a Korn shell feature that's also available
in bash and some other shells.  This patch implements process
substitution in ash when ASH_BASH_COMPAT is enabled.

v2: Replace array of file descriptors with a linked list.
    Include tests that were unaccountably omitted from v1.
v3: Update linked list code to the intended version.
v4: Change order of conditional code in cmdputs().
v5: Use existing popredir() mechanism to manage file descriptors.
v6: Rebase to latest version of BusyBox ash.  Reduce code churn.
