Bash 5.0 added the dynamic variable EPOCHSECONDS and EPOCHREALTIME
which return the number of seconds since the Unix Epoch as an
integer or float. These are useful for logging or tracing.

Embedded scripts require a shell to be present in the BusyBox
binary. Allow either ash or hush to be used for this purpose.
If both are enabled ash takes precedence.
The size of the binary is unchanged in the default configuration:
both ash and hush are present but support for embedded scripts
isn't compiled into hush.

Was printing initial "+" prefix for the assignment, that printing
"+ cmd"
then printing the expanded " v=VAL" string.

The n > 0 check to prevent access to the last byte of non-existing argv[-1]
wasn't enough. Switched to making sure there are initialized (zero) bytes there.
A predictable testcase is rather hard to construct, unfortunately,
contents of memory depends on allocator behavior and whatnot.

This necessitates switch from libc FILE api to a simple
homegrown replacement.
The change which fixes the bug here is the deleting of
restore_redirected_FILEs();
line. It was prematurely moving (restoring) script fd#3.
The fix is: we don't even _want_ to restore scrit fds,
we are perfectly fine with them being moved.
The only reason we tried to restore them is that FILE api
did not allow moving of FILE->fd.

This is necessary since expand_one_var() for ${var:+ARG} must create more than one
