Add syntactic predicates to remove the need to backtrack when evaluation
the arg rule.

Remove need to backtrack from the word rule

All the other alternatives can also be matched from fname so we need
syntactic predicates. We should give thought to if we need both the word
and fname rules.

Change string literals to tokens in parser rules.

String literals in parser rules will create unnecessary tokens
which have already been defined. So we use tokens instead.

Unreachable alternative removal

Remove underscore alternative from ns_str_part_no_res as it could never
be matched because name before it would always catch it.

Simplify reserved word handling in strings

The paths for strings with reserved words and strings that can't be
reserved code can share most of the code. Now the inclusion of reserved
words is done with the top level rules so we can remove the duplicated
listing.

Remove special handling for let

let is a builtin like echo so it should not have any special handling in
the parser. Fixes bug #363029.

Simplify the variable expansion rule

Moved things related to replacement matching to helper rules for simpler
code. The parenthesis for offset operators are already handled by the
explicit_arithmetic rule.

Refactor nqstr rule for readability

Move each alternative to own line, rename to nsqrt_part and move the
plus operator the callers. This should make the rule easier to read.

Move functions to @member section

It's more proper to declare functions in @member section rather
than @postinclude section. Blank lines are added for better
readability.

Parser: improve arithmetic white space handling

We don't have to list blank on both sides of operators. Now the code
follows the rule of always looking at white space after operators.

Reorder arithmetic expansion related rules so that they flow logically

Parser: Left-factor variable expansion

There was a lot of bactracking going on in the var_exp rule.
Left-factoring brings down versionator memory usage from around 1 GB to
200 MB.

The massif and benchmark_parser make targets show that we benefit
greatly from turning on memoization.

Walker: change the implementation of index searching

We used recursive counting algorithm to find the index of LT(2).
Now it's changed to recurrence algorithm that directly traverse the
input stream. This can benefit function definition and compound
command.

Parser: move LOCAL token to ns_str_part

"local" is not a reserved word so it shouldn't be put to res_word_str.
Now it's moved to ns_str_part.

This change is hard to get tested. Eclasses now fail to parse if the
