sh: Save/restore changed variables in optimized command substitution.
In optimized command substitution, save and restore any variables
changed by expansions (${var=value} and $((var=assigned))), instead of
trying to determine if an expansion may cause such changes.
If $! is referenced in optimized command substitution, do not cause jobs
to be remembered longer.
This fixes $(jobs $!) again, simplifies the man page and shortens the
code.

This is required by POSIX, and allows things like ENV=\$HOME/.shrc.

If IFS is null, unquoted $@/$* should still expand to separate words.
This differs from quoted $@ (which does not depend on IFS) in that
pathname generation is performed and empty words are removed.

sh: Fix bss-based buffer overflow in . builtin.
If the length of a directory in PATH together with the given filename
exceeded FILENAME_MAX (which may happen even for pathnames that work), a
static buffer was overflown.
The static buffer is unnecessary, we can use the stalloc() stack.
