6db68bc7f7 add test for constexpr switch_parser 
The test led to the following error before:
github_issues.cpp(522): error C3615: constexpr function
'boost::parser::switch_' cannot result in a constant expression

885595f7bd Parse the attribute of quoted_string into a temporary, and assign at the end, 
if successful.  This makes the code well-formed when the attribute type is an
optional.

Addresses PR #290.

0eacce6080 Add special-casing of nope attributes in seq_parser, so that seq_parser does 
not assign over valid values in a sequence's attribute after successfully
parsing a subsquent nope-attributes parser.

c674e94c3d Don't reuse the attribute-generating path in rule_parser's out-param overload 
of call.  Doing so was wiping out previous partial results, in cases like foo
>> bar, where foo produces a T, and bar is a rule that produces vector<T>.

Fixes #248.

94a9daec40 Change the way that the pending operations are applied to symbol table 
parsers.  Instead of trying to find all of them at the start of the top-level
parse, they are recorded in the context, and then applied at the end of the
top-level parse.  The previous technique did not work, simplt because the
top-level parse cannot see all the parser involded -- some are behind rule
firewalls, by design.

Related to #183.
Fixes #204.

d774edc0e6 Add the condition that BOOST_PARSER_USE_CONCEPTS is true to/in place of many 
places that used __cpp_lib{concepts,ranges} previously.  This is often

implementation of concepts.

87b50154cf Fix incorrect attribute returned by a rule in some cases. The problem was 
that the changes to support recursive rules made all rules use the out-arg
overload of parse_rule.  This is wrong.  Now, rules use the
attribute-returning overload unless asked explicitly to use the out-arg one,
*or* if the rule is being invoked recursively, and we are in an iteration
after the 0th.

Fixes #125.
