Summary: specifying headers for extensions

Initial Comment:
This patch allows to specify that C header files are 
part of source files for dependency checking. 
The 'sources' list in Extension instances can be 
simple filenames as before, but they can also be 
SourceFile instances created by

SourceFile("myfile.c", headers=["inc1.h", "inc2.h"]).

Unfortunately not only changes to command.build_ext 
and command.build_clib had to be made, also all the 
ccompiler (sub)classes have to be changed because the 
ccompiler does the actual dependency checking. I 
updated all the ccompiler subclasses except 
mwerkscompiler.py, but only msvccompiler has actually 
been tested.

The argument list which dep_util.newer_pairwise() now 
accepts has changed, the first arg must now be a 
sequence of SourceFile instances. This may be 
problematic, better would IMO be to move this function 
(with a new name?) into ccompiler.
