ash: refresh stack pointers after makestrspace in rmescapes
...
Without this, rmescapes sometimes returns random garbage while
performing parameter expansions such as ${foo#bar}, in the event that
the allocation of r happens to need to reallocate the stack and hence
invalidate str and p. I'd love to provide a test case but unfortunately
it's dependent on exact stack layout, so I don't have anything simpler
than the situation described in
https://bugs.launchpad.net/ubuntu/+source/partman-base/+bug/527401/comments/23
which involved a sequence of foo="${foo#*, }" expansions on a long
string inside our RAID configuration tool.
The same fix has been in dash since 2007-09-26, contributed by Roy
Marples <uberlord@gentoo.org>. I actually came up with it independently
almost to the character, but then synced it up with the variable naming
used in dash when I noticed that change afterwards.

ash: fix quadratic matching slowdown is ${v/*foo*/repl} (really bad one)
...
It is especially bad with patterns starting with "*".
With ASH_OPTIMIZE_FOR_SIZE=y, only those are optimized, +few bytes:

836341 441 7564 844346 ce23a busybox_unstripped
With ASH_OPTIMIZE_FOR_SIZE off, we also optimize patterns _ending_ with "*",
which costs about 80 bytes:

In the process, split the $PATH searching code out of builtin_source() and
into its own find_in_path() function so we don't duplicate it.

Only very rudimentary testing was done.
With function support off, code growth is zero, with it on:

Add TODOs.
Disable redir4.right part where we differ from bash.
It is not a bug per standards.
Add a few tests, one is in hush-bugs section:
and_or_and_backgrounding.right. It will likely bite users
in real world usage.
