88abb615aa Add pre_- and post_parser members to parser_modifiers; these are used as 
look-ahead/-behind positive or negative assertions.

When combining parsers using op>> and op>, if either side is an expect_parser
and the other side has an open pre_-/post_parser slot, take the subparser out
of the expect_parser, and use it directly in the pre_-/post_parser slot.

See #160.

54f8eecfe6 Change the no_case[] directive to use the parser_modifiers struct, like omit[] 
does; remove no_case_parser.

See #160.

2f7e5964a6 Apply the same sort of change as the previous two commits, but to all the 
parsers not already modified.  Generalize with_parser_mods().  Remove
omit_parser, since it is now moot.

See #160.

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.

1e64b6e416 Add insert/erase/clear operations on symbol tables for the current parse and 
subsequent parses both. Add better tests for the added API and the previous
subset of the operations already present. Fix errors revealed by the tests.

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
necessary when concepts are disabled, since the user might have a broken
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.

27506af2f3 Constrain parse() overloads that take an out-attribute Attr & -- but no 
skipper -- so that Attr is not derived from a specialization of
parser_interface.  This prevents this from being the best overload when using
a mutable skipper, and producing lots of diagnostics that say the skipper
(which would be mistakenly bound to Attr &) is not assignable from whatever
the attribute type is.

Fixes #105.
