Use assert instead of if without else to ensure an object pointer is not NULL.
gcc complained that a variable might be used uninitialized, which is
true. If NULL is passed, all code gets executed with an
uninitialized variable which is an error in almost every case.
Since python itself never passes NULL, only a real error in
other c code could trigger the assert.

Fix classmethod for use in cdef classes.
The issue here (as pointed out by Thomas Hunger) is that once the CClass
body gets executed the class is already constructed, and its methods
are actual methods not functions (as in Python).
The CClassScope now returns a utility function on lookup of "classmethod"
that creates a class method out of a method (rather than out of a function).
When added to the type dictionary, the result is exactly the same as setting
the METH_CLASS flag.

Added a bint c type, which is a c int that coerces to and from python objects via the boolean routines.
The purpose of this type is to free the coder from having to use
bool() when retrieving and returning semantically "boolean" values
(e.g. the result of a compare).
The bint type is a subclass of the int type, and the only difference
is that it uses PyBool_FromLong and PyObject_IsTrue rather than
PyInt_FromLong and PyInt_AsLong. Arithmatic on bints will return ints.
Where it makes sense, several builtin functions have been re-declared
to return bints, as well as comparisons and the boolean operations
or, and, and not.

Cache __builtin__ name lookups so they are performed on module load rather than at every use.
The code "__Pyx_GetName(__pyx_b, __pyx_n_[string])" is performed in several
thousand places throughout the sage library, and can be quite expensive
(a dictionary lookup, possibly raising an error, etc.) This is redundant
as the result will always be the same. I perform the lookup once
(on loading the module), then have a pointer to the result for all subsequent use.
The most common examples are bool/str/int (both as function calls and
in isinstance), True/False, and raisign errors.
A side feature is that on loading a module with an illegal __builtin__ name,
it will complain at load time rather than at run time.

Inline keyword for cdef functions, variable assignment on declaration (+optimization)
"cdef inline foo()" now valid, and will place inline in the resulting c code

This may not seem like a huge change, but it ended up requiring
quite a bit of work. The variables are still all declared at the
top, but the assignment takes place at the specified line in the
code.
If an assignment is made at declaration, the variable is initalized to
0 rather than None (also skipping an INCREF) and Py_XDECREF is used on
exiting the function (in case an error occured before the actual value
was calculated). Hence these variables MUST NOT be used before they are
defined or it will probably segfault.
