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.

d873d7ea80 Provide failover empty symbol table tries for use inside of skippers, since 
nothing prevents using a symbol_parser in a skipper, and the previous commit
introduced nullptr skipper data tables in some cases.

bfa3e33372 Reduce compilation time by using SkipParser when determining attribute type. 
When using a large parser, the whole tree of parsers in instantiated with the
skip (whitespace) parser used. Then, it was instantiated again without a skip
parser, just to determine the attribute type.
This patch changes the code so the attribute type is determined *with* the
skip parser. That way, the number of template instantiations
required are halved for some use cases.

With gcc 14.2, the instantiations without the skip parser even ended up in the
binary. In that case, this patch reduces binary size.
This is most likely a compiler bug, as the usage is in decltype().

c32d594d64 Eliminate double-instantiation of context templates (due to on a difference

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.

39faa9ddbe Pass the sentinel type as a template parameter to the iterator template in 
project_view, as a workaround to the presence/absence of a disambiguating
template keyword in iterator's implementation.  Neither adding it nor temoving
it works for all builds.  Also, re-enable the C++17 MSVC 2022 Github build.

Fixes #252.

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.
