Move struc-symbol.h to symbols.c

This file was never supposed to be widely used.  The fact that it has
found its way into many gas files led to bugs, typically when code
expecting a symbolS* to point at a struct symbol is presented with a
struct local_symbol.  Also, commit 158184ac9e changed these structs in
2012 but didn't catch all places where symbol bsym was being used to
test for a local_symbol.

	* Makefile.am (HFILES): Delete struc-symbol.h.
	* doc/internals.texi: Delete struc-symbol.h reference and out
	of date local symbol description.

	* cgen.c: Don't #include struc-symbol.h.
	(gas_cgen_parse_operand): Don't test for local_symbol using
	bsym, instead call symbol_symbolS.  Use symbol_get_bfdsym.
	(weak_operand_overflow_check, make_right_shifted_expr): Use
	symbol accessors.
	* config/obj-coff.c: Don't #include struc-symbol.h.
