Base regex code on char_class_type.
...
__get_classname() and __bracket_expression were assuming that
char_class_type was ctype_base::mask rather than using
regex_traits<_CharT>::char_class_type.
This change allows char_class_type to be defined to something other than
ctype_base::mask so that the implementation will still work for
platforms with an 8-bit ctype mask (such as Android and OpenBSD).

Implement LWG issue 2306: match_results::reference should be value_type&, not const value_type&. This is a general move by the LWG to have the reference type of read-only containers be a non-const reference; however, there are no methods that return a non-const reference to a match_result entry, so there's no worries about getting a non-const reference to a constant object.

Patch by GM: apparently '__value' (two underscores) is a special name in Visual Studio, so rename the private method in <regex> with that name. GM's patch used '___value' (three underscores), but I changed that to '__regex_traits_value' because I've been burned in the past by identifiers that appear identical but are not.

First loop test passed. The data structure and search algorithm is still crude and in-flux. But this milestone needed to be locked in. Right now every loop is implemented in terms of a structure that will handle the most complicated {min, max} loop. Though only *-loops are tested at the moment. In a future iteration *-loops will likely be optimized a little more. The only tests are for basic posix so far, but I have prototype code running for extended posix and ecma. The prototype code lacks the complicating properties of the real <regex> requirements though.
