bpo-40421: Add PyFrame_GetCode() function (GH-19757)
PyFrame_GetCode(frame): return a borrowed reference to the frame
code.

Replace frame->f_code with PyFrame_GetCode(frame) in most code,
except in frameobject.c, genobject.c and ceval.c.

Also add PyFrame_GetLineNumber() to the limited C API.

bpo-40421: Add pyframe.h header file (GH-19755)
Add a new separated pyframe.h header file of the PyFrame public C
API: it is included by Python.h.

Add PyFrame_GetLineNumber() to the limited C API.

Replace "struct _frame" with "PyFrameObject" in header files.
PyFrameObject is now defined as struct _frame by pyframe.h which is
included early enough in Python.h.

  PyCode_NewEmpty:
  Most uses of PyCode_New found by http://www.google.com/codesearch?q=PyCode_New
  are trying to build an empty code object, usually to put it in a dummy frame
  object. This patch adds a PyCode_NewEmpty wrapper which lets the user specify
  just the filename, function name, and first line number, instead of also
  requiring lots of code internals.

  Issue 5954, PyFrame_GetLineNumber:
  Most uses of PyCode_Addr2Line
  (http://www.google.com/codesearch?q=PyCode_Addr2Line) are just trying to get
  the line number of a specified frame, but there's no way to do that directly.
  Forcing people to go through the code object makes them know more about the
  guts of the interpreter than they should need.

  The remaining uses of PyCode_Addr2Line seem to be getting the line from a
  traceback (for example,
  http://www.google.com/codesearch/p?hl=en#u_9_nDrchrw/pygame-1.7.1release/src/base.c&q=PyCode_Addr2Line),
  which is replaced by the tb_lineno field.  So we may be able to deprecate
  PyCode_Addr2Line entirely for external use.

  Issue #6042:
  lnotab-based tracing is very complicated and isn't documented very well.  There
  were at least 3 comment blocks purporting to document co_lnotab, and none did a
  very good job. This patch unifies them into Objects/lnotab_notes.txt which
  tries to completely capture the current state of affairs.

  I also discovered that we've attached 2 layers of patches to the basic tracing
  scheme. The first layer avoids jumping to instructions that don't start a line,
  to avoid problems in if statements and while loops.  The second layer
  discovered that jumps backward do need to trace at instructions that don't
  start a line, so it added extra lnotab entries for 'while' and 'for' loops, and
  added a special case for backward jumps within the same line. I replaced these
  patches by just treating forward and backward jumps differently.
