ea7d2f6ec0 ash: fix error code regression 
The commit 'ash,hush: set exit code 127 in "sh /does/not/exist" case'
only partly implemented the dash commit '[ERROR] Allow the originator
of EXERROR to set the exit status'.  This resulted in incorrect error
codes for a syntax error:

   $ )
   $ echo $?
   0

or a redirection error for a special builtin:

   $ rm -f xxx
   $ eval cat <xxx
   $ echo $?
   0

Also add tests. wait5.tests so far fails (but works for ash and dash).

It was not properly interruptible, and did not update job status
(the exited processes were still thought of as running).

eb17b6f6c9 ash: eval: Return status in eval functions 
Backported from dash:

    eval: Return status in eval functions

    The exit status is currently clobbered too early for case statements
    and loops.  This patch fixes it by making the eval functions return
    the current exit status and setting them in one place -- evaltree.

    Harald van Dijk pointed out a number of bugs in the original patch.
