PEGTL 1.2.0

• Added pegtl_string_t and pegtl_istring_t to simplify string definitions as follows:

   pegtl::string< 'h', 'e', 'l', 'l', 'o' >  // Normal
   pegtl_string_t( "hello" )                 // New shortcut

• Added examples/abnf2pegtl.cc application that converts grammars based on ABNF (RFC 5234) into a PEGTL C++ grammar.
• Added contrib/alphabet.hh with integer constants for alphabetic ASCII letters.

PEGTL 1.1.0

• Renamed namespace pegtl::ucs4 to pegtl::utf32 and generally adopted UTF-32 in all naming.
• Added experimental support for UTF-16 similar to the previously existing UTF-32 parsing rules.
• Added support for merging escaped UTF-16 surrogate pairs to pegtl/contrib/unescape.hh.
• Fixed incorrect handling of escaped UTF-16 surrogate pairs in the JSON examples.
• A state's S::success()-method can now have an extended signature to get access to the current apply_mode, action- and control class (template).
• The contrib/raw_string class template now calls Action<raw_string<...>::content>::apply() with the user's state(s).
