Disable yield-from integration test with asyncio in Py3.7 since asyncio Python coroutines are no longer iterable.

Closes #2111.

Re-enable method unpacking inside of the module init function if the call occurs inside of a loop (probably still worth it there).
See #2102.

Disable method unpacking inside of module init function by default as it really just increases the code size to uselessly speed up one-time code.
See #2102.

Closes #2106.

Do not compare the "writable_needed" flag when comparing memory views that condition is too strict and it is not currently used anyway.

implement read-only memoryviews

DOC: BUG: suggest install numpy debugging

or you get import error for `multiarray_d.so`

Repair memslice test after disabling auto-detection of read-only views, but keep some of the tests for 'const' views as smoke tests.

Disable auto-detection of read-only memory views (too unsafe) and acquire them only as read-only if the memory view dtype is a "const" type.

In Python 3, an unbound method is just a function

See #2102.

Specify license in cython-mode.el's header

Rewrite documentation paragraph on automatic string encoding for clarity

Disallow memory views as struct members since structs do not allow safe buffer reference management.

Use NamedTemporaryFile instead of mkstemp

Move user branch hint generation from IfClauseNode into IfStatNode to include also the inverse 'else' condition.

Inject branch hints for user conditionals that raise exceptions as we can expect them to be unlikely.
