[RFA] Fix cygwin compilation failure for python code

["Pierre Muller" <pierre.muller@ics-cnrs.unistra.fr>]

  Using Cygwin, I got several compilation failures
related to the incomplete struct symtab_and_line
used as parameter in function
symtab_and_line_to_sal_object.

  The patch below allows for me to 
read in "symtab.h" before "python-internal.h" is read,
and thus get a real definition of the symtab_and_line struct.

  I wonder why I am the only one having this 
problem?

  Is this patch OK? Otherwise,
how should such problems be handled?

	* py-lazy-string.c: Move "python-internal.h"
	inlcusion to allow compilation.
	* py-objfile.c: Idem.
	* py-utils.c: Add "symtab.h" header to allow compilation.
