Purge stray occurrences of "void *" from code base.

* lib.c (cobj_print_op): In the format call, cast
the C pointer to val, since the ~p conversion now
takes a val rather than void *.
(cptr_equal_op, obj_print, obj_pprint): Remove cast to
void *, since obj now already has the type that ~p expects.

* lib.h (struct any): Use mem_t * instead of void *.

* parser.h (yyscan_t): Repeat the definition from inside
the Flex-generated lex.yy.c.
(yylex_init, yylex_destroy, yyget_extra, yyset_extra): Re-declare
using yyscan_t typedef in place of void *.

* parser.l (yyget_column, yyerrprepf): Re-declare using yyscan_t.
(grammar): Use yyg in place of yyscanner in calls to yyerrprepf.

* parser.y (yylex, %lex-param): Use yyscan_t instead of void *.
(parse): Use yyscan_t for local variable.

* signal.c (stack): Change type from void * to mem_t *.

* stream.c (vformat): Conversion specifier p extracts val
instead of void *.
(run): Use casts that only remove const, not all the way to void *.

* txr.1: Documented p conversion specifier of format.

* Makefile (OBJS-y): Initialize with := to make sure it is a
simple variable, and not a macro.
(SRCS): New variable, listing source files.
(enforce): New rule for enforcing coding conventions.
Currently checks for void * occurrences.
