BUG: fix crash when sending interrupt signal to fft functions

the SIGINT handling code must be in the GIL released section so the
longjmp does not skip the retaking.
This implies that the signal handlers must use thread local storage to
avoid a crash when sending interrupt to threaded fft functions.
Distribution of SIGINT to each threads must be handled by the
application as only the master thread receives it
Closes gh-4634

BUG: Properly parse ufunc methods with PyUFunc_CheckOverride.
BUG: Fix and add ufunc override capabilities to ufunc methods.
TST: Add tests for ufunc.method overrides.
BUG, TST: Fix tests of ma.count return type.

The masked array count method was fixed to use np.intp when doing sums.
The return type is always np.intp except for count(arr, axis=None) when
arr has no mask, in which case the return type is that of ndarray.size.

The test errors were noted in #4698.
