failing test case for strided memmap
FIX: potential segfault when reconstructing non-contiguous memmap

The strided_from_memmap helper function failed to mmap enough data from the
backing file potentially causing invalid memory access.

The fix is to compute the bounding buffer size in the reduce_memmap function
and use that as shape argument for the memmap constructor and only then cast
the resulting array with provided shape and strides.
TST: check non-unit step slicing

ENH: Make MemorizedFunc __doc__ autodoc-compatible
DOC: the make-like features were removed a long time ago.
FIX: make test_memorized_repr pass under windows

Using eval(repr(memoized_func)) is not safe under windows as the
backslash path separator is not interpreted correctly.
ENH: memory robust to modification of source files

This instores an in-memory hash that is used to check if functions are
modified rather than looking at the source code.

The main benefit is that if the source code has been modified after the
function has been loaded, it is out of sync with the function in the
interpretor, and thus can lead to spurious cash flushes.
