Subject: [PATCH] BUG: Choose a more unique PY_ARRAY_UNIQUE_SYMBOL in f2py.

In a few exceptional cases where symbols are shared between different

Python modules the use of `PyArray_API` in f2py (fortranobject.h)

conflicts with the regular use of the same symbol in the multiarray

module. Generally the symptom of this conflicting use is a segfault

when importing a f2py'ed module. This occurs because the module init

code somehow overwrites the first element of `PyArray_API` with the

location of `PyArray_API`, causing a crash when

`PyArray_GetNDArrayCVersion` is called.

Closes gh-2521.
