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.

shell: also do word splitting when -d DELIM is used
...
The original commit 3bef5d89b0
introduced an additional check
for an unset `opt_d` before doing word splitting. I'm unsure
why it's there in the first place, but the commit message also
describes a different behaviour than what -d actually does in
bash, while the code mostly does the right thing.
`opt_d` sets the line delimiter for read to stop reading and
should not affect word splitting.
Testcase:
$ echo qwe rty | { read -d Z a b; echo a:$a b:$b; }
a:qwe b:rty
