ash: fix breakage of ${v/pat/str}
...
The commit
ash: move parse-time quote flag detection to run-time
breaks pattern substitution in parameter expansion. Fix this and
revise the code so that the different handling of the pattern and
the replacement string takes place in rmescapes rather than the
separate function parse_sub_pattern.

ash: move parse-time quote flag detection to run-time
...
Because the parser does not recursively parse parameter expansion
with respect to quotes, we can't accurately determine quote status at
parse time. This patch works around this by moving the quote detection
to run-time where we do interpret it recursively.
Test case:
foo=\\ echo "<${foo#[\\]}>"
Old result:
<\>
New result:
<>
Do not quote back slashes in parameter expansions outside quotes.
Test case:
a=/b/c/*
b=\\
echo ${a%$b*}
Old result:
/b/c/*
New result:
/b/c/
