      merge count_size_as_multibyte, parse_str_to_multibyte · de883a70
      Paul Eggert authored
      * character.c, character.h (count_size_as_multibyte):
      Renamed from parse_str_to_multibyte; all uses changed.
      Check for integer overflow.
      * insdel.c, lisp.h (count_size_as_multibyte): Remove,
      since it's now a duplicate of the other.  This is more of
      a character than a buffer op, so better that it's in character.c.
      * fns.c, print.c: Adjust to above changes.

      	The next log entry shows the actual changes by Paul Eggert.
      
       Fix a problem with aliasing and vector headers.
       GCC 4.6.0 optimizes based on type-based alias analysis.  For
       example, if b is of type struct buffer * and v of type struct
       Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
       != &v->size, and therefore "v->size = 1; b->size = 2; return
       v->size;" must therefore return 1.  This assumption is incorrect
       for Emacs, since it type-puns struct Lisp_Vector * with many other
       types.  To fix this problem, this patch adds a new type struct
       vector_header that documents the constraints on layout of vectors
       and pseudovectors, and helps optimizing compilers not get fooled
       by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
       XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
       src/lisp.h (XVECTOR_SIZE): New convenience macro.  All previous uses of
       XVECTOR (foo)->size replaced to use this macro, to avoid the hassle
       of writing XVECTOR (foo)->header.size.
       src/lisp.h: Say "vectorlike header" rather than "vector header.
       (struct vectorlike_header): Rename from struct vector_header.
       (XVECTORLIKE_HEADER_SIZE): Renamed from XVECTOR_HEADER_SIZE.
       All uses changed.
       (XVECTOR_HEADER_SIZE): New macro, for use in XSETPSEUDOVECTOR.
       (XSETTYPED_PVECTYPE): New macro, specifying the name of the size
       member.
       (XSETPVECTYPE): Rewrite in terms of new macro.
       (XSETPVECTYPESIZE): New macro, specifying both type and size.
       This is a bit clearer, and further avoids the possibility of
       undesirable aliasing.
       (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
       (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR
       and XVECTOR_HEADER_SIZE.
       (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
       since Lisp_Subr is a special case (no "next" field).
       (ASIZE): Rewrite in terms of XVECTOR_SIZE.
       (struct vector_header): New type.
       (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
       object, to help avoid aliasing.
       (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
       (SUBRP): Likewise, since Lisp_Subr is a special case.
       src/lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
       (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
       (struct Lisp_Hash_Table): Combine first two members into a single
       struct vector_header member.  All uses of "size" and "next" members
       changed to be "header.size" and "header.next".
       src/buffer.h (struct buffer): Likewise.
       src/font.h (struct font_spec, struct font_entity, struct font): Likewise.
       src/frame.h (struct frame): Likewise.
       src/process.h (struct Lisp_Process): Likewise.
       src/termhooks.h (struct terminal): Likewise.
       src/window.c (struct save_window_data, struct saved_window): Likewise.
       src/window.h (struct window): Likewise.
       src/alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
       Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
       src/buffer.c (init_buffer_once): Likewise.
       src/lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
       special case.
       src/process.c (Fformat_network_address): Use local var for size,
       for brevity.
       src/fns.c (vector): Remove; this old hack is no longer needed.
       src/bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
