* parser.h
Move some declarations in the raw-parser header files to create a clearer distinction between the external API (parser.h) and declarations that only need to be visible within the raw parser code (gramparse.h, which now is only included by parser.c, gram.y, scan.l, and keywords.c). This is in preparation for the upcoming change to a reentrant lexer, which will require referencing YYSTYPE in the declarations of base_yylex and filtered_base_yylex, hence gram.h will have to be included by gramparse.h. We don't want any more files than absolutely necessary to depend on gram.h, so some cleanup is called for.

#include "nodes/parsenodes.h"
Restructure some header files a bit, in particular heapam.h, by removing some unnecessary #include lines in it. Also, move some tuple routine prototypes and macros to htup.h, which allows removal of heapam.h inclusion from some .c files. For this to work, a new header file access/sysattr.h needed to be created, initially containing attribute numbers of system columns, for pg_dump usage. While at it, make contrib ltree, intarray and hstore header files more consistent with our header style.

Infrastructure for deducing Param types from context, in the same way that the types of untyped string-literal constants are deduced (ie, when coerce_type is applied to 'em, that's what the type must be). Remove the ancient hack of storing the input Param-types array as a global variable, and put the info into ParseState instead. This touches a lot of files because of adjustment of routine parameter lists, but it's really not a large patch. Note: PREPARE statement still insists on exact specification of parameter types, but that could easily be relaxed now, if we wanted to do so.

extern List *raw_parser(const char *str);
Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments.

Rethink the idea of having plpgsql depend on parser/gram.h. Aside from the fact that this is breaking the MSVC build, it's probably not really a good idea to expand the dependencies of gram.h any further than the core parser; for instance the value of SCONST might depend on which bison version you'd built with. Better to expose an additional call point in parser.c, so move what I had put into pl_funcs.c into parser.c. Also PGDLLIMPORT'ify the reference to standard_conforming_strings, per buildfarm results.
