Doing so just makes all methods implicitly nogil. This also makes nogil
on a cdef extern from statement do the right thing to cppclasses (and
their methods) contained inside.

clean up dependencies of memoryview utility code snippets a bit to get rid of some 'unused function' C compiler warnings

work around inability to detect existing Python globals (e.g. from imports) when cpdef-ing global functions

Relax stride check for zero- and one-sized dimensions

remove redundant importing overhead for newly built test module in test runner and make sure we always import exactly the one we just built

Naive approach to fix memview incref/decref asymmetry in transpose
