parser: Fix parameter expansion inside inner double quotes
The parsing of parameter expansion inside inner double quotes
breaks because we never look for ENDVAR while innerdq is true.
echo "${x#"${x+''}"''}
This patch fixes it by pushing the syntax stack if innerdq is
true and we enter a new parameter expansion.
This patch also fixes a corner case where a bad substitution error
occurs within arithmetic expansion.

Upstream email:
This is actually composed of two bugs. First of all our tracking
of quotemark is wrong so anything after "$@" becomes quoted. Once
we fix that then the problem is that the first space character
after "$@" is not recognised as an IFS.
This patch fixes both.

parser: Fix single-quoted patterns in here-documents
The script
x=*
cat <<- EOF
${x#'*'}
EOF
prints * instead of nothing as it should. The problem is that
when we're in sqsyntax context in a here-document, we won't add
CTLESC as we should. This patch fixes it:

parser: Add syntax stack for recursive parsing
Without a stack of syntaxes we cannot correctly these two cases
together:
"${a#'$$'}"
"${a#"${b-'$$'}"}"
A recursive parser also helps in some other corner cases such
as nested arithmetic expansion with paratheses.
This patch adds a syntax stack allocated from the stack using
alloca. As a side-effect this allows us to remove the naked
backslashes for patterns within double-quotes, which means that
EXP_QPAT also has to go.
This patch also fixes removes any backslashes that precede right
braces when they are present within a parameter expansion context,
and backslashes that precede double quotes within inner double
quotes inside a parameter expansion in a here-document context.
The idea of a recursive parser is based on a patch by Harald van
Dijk.

This fragment did not work right:
temp = bb_get_chunk_from_file(fp, &len);
if (temp) {
/* len > 0 here, it's ok to do temp[len-1] */
char c = temp[len-1];
With "int len" _sign-extending_, temp[len-1] can refer to a wrong location
if len > 0x7fffffff.

parser: Fix backquote support in here-document EOF mark
Currently using backquotes in a here-document EOF mark is broken
because dash tries to do command substitution on it. This patch
fixes it by checking whether we're looking for an EOF mark during
