48cb983b13 ash: parser: Get rid of PEOA
Upstream commit:

    Date: Wed, 27 May 2020 12:19:13 +1000
    parser: Get rid of PEOA

    PEOA is a special character used to mark an alias as being finished
    so that we don't enter an infinite loop with nested aliases.  It
    complicates the parser because we have to ensure that it is skipped
    where necessary and not copied to the resulting token text.

    This patch removes it and instead delays the marking of aliases
    until the second pgetc.  This has the same effect as the current
    PEOA code while keeping the complexities within the input code.

This adds ~32 bytes of global data:

8c68ae8416 ash: parser: Fix alias expansion after heredoc or newlines
Upstream commit:

    Date: Wed, 29 Apr 2020 00:19:59 +1000
    parser: Fix alias expansion after heredoc or newlines

    This script should print OK:

        alias a="case x in " b=x
        a
        b) echo BAD;; esac

        alias BEGIN={ END=}
        BEGIN
    	cat <<- EOF > /dev/null
    		$(:)
    	EOF
        END
        : <<- EOF &&
    		$(:)
        EOF
        BEGIN
    	echo OK
        END

    However, because the value of checkkwd is either zeroed when it
    shouldn't, or isn't zeroed when it should, dash currently gets
    it wrong in every case.

    This patch fixes it by saving checkkwd and zeroing it where needed.

c540256127 ash: use pgetc_eatbnl() in more places, take 3
Adding previously skipped "readtoken1(pgetc_eatbnl(), syntax_type..." change
from upstream commit:

    Date:   Thu Mar 8 08:37:11 2018 +0100
    parser: use pgetc_eatbnl() in more places

    dash has a pgetc_eatbnl function in parser.c which skips any
    backslash-newline combinations. It's not used everywhere it could be.
    There is also some duplicated backslash-newline handling elsewhere in
    parser.c. Replace most of the calls to pgetc() with calls to
    pgetc_eatbnl() and remove the duplicated backslash-newline handling.

Testcase:
	PS1='\
	:::'
should result in ::: prompt, not <newline>::: prompt

    This patch saves and restores the heredoclist in expandstr.

    It also removes a bunch of unnecessary volatiles as those variables
    are only referenced in case of a longjmp other than one started by
    a signal like SIGINT.

Upstream commit:

    Date: Tue, 28 Apr 2020 01:15:26 +1000
    parser: Fix handling of empty aliases

    Dash was incorrectly handling empty aliases. When attempting to use an
    empty alias with nothing else, I'm (incorrectly) prompted for more
    input:

    ```
    $ alias empty=''
    $ empty
    >
    ```

    Other shells (e.g., bash, yash) correctly handle the lone, empty alias as an
    empty command:

    ```
    $ alias empty=''
    $ empty
    $
    ```

    The problem here is that we incorrectly enter the loop eating TNLs
    in readtoken().  This patch fixes it by setting checkkwd correctly.

    Thanks for the report.  This is actually a fairly old bug with
    set -e that's just been exposed by the exit status change.  What's
    really happening is that cleanup itself is triggering a set -e
    exit incorrectly because evaltree cached the value of eflag prior
    to the function call.

    This patch moves the nflag check from cmdloop into evaltree.  This
    is so that nflag will be in force even if we enter the shell via a
    path other than cmdloop, e.g., through sh -c.

4a36ef11ac ash: regressions in process substitution
Stacy Harper reports that this script:

   test() { . /tmp/bb_test; }
   echo "export TEST=foo" >/tmp/bb_test
   test 2>/dev/null
   echo "$TEST"

correctly prints 'foo' in BusyBox 1.33 but hangs in 1.34.

Bisection suggested the problem was caused by commit a1b0d3856 (ash: add
process substitution in bash-compatibility mode).  Removing the call to
unwindredir() in cmdloop() introduced in that commit makes the script
work again.

Additionally, these examples of process substitution:

   while true; do cat <(echo hi); done
   f() { while true; do cat <(echo hi); done }
   f

result in running out of file descriptors.  This is a regression from
v5 of the process substitution patch caused by changes to evalcommand()
not being transferred to v6.

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.

1b30c63dfd 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
