ENH: use dot (BLAS!) in linalg.norm
MAINT: dotblas: factor out all gemm and gemv calls
BUG: fix missing check for memory allocation failure in ufuncs

closes gh-4018
DEP: non-integer scalar python sequence repeat

This starts deprecation for code such as
np.float_(3.4) * [1, 2]
which should only work for integer objects. It may be possible
to just return NotImplemented since at least python sequences
implement their multiply themself through __index__.

Further action is only needed for PyArray_PyIntAsIntp, so this
is part of a larger deprecation now.

Closes gh-4036
DOC: Add an example of casting array type and byte order using astype.
DOC: Spelling correction for numpy.diag see also
Merge pull request #4037 from migueldvb/docs

Example to convert the type of an array using the astype method and minor typo fix
Updated FAQ with links to github issues page etc

Removed some questions that are no longer relevant
Moved old news from README.txt to OLDNEWS.txt
Changed CVS cens.ioc.ee documentation links to link to GitHub
Spelling: loose -> lose
spelling: AC -> AD in years

(could also use BCE and CE to be more politically correct)
BUG: ma.compressed() function returns masked array

When a masked array with nomask was passed to ma.compressed()
function, the result was the original masked array instead of
an ndarray.

Closes gh-4026.

BUG: ma.compressed() function returns masked array
ENH: check if type is basic python type before checking for __numpy_ufunc__

improves performance of scalar conversions (x + .5) by ~30%.

Spelling & notation corrections
MAINT: initialize strides for ufunc.at

avoids uninitialized use errors from valgrind, value of strides is
irrelevant as count is always 1.
BUG: fix uninitialized use in _strided_to_strided_string_to_datetime

dt == NPY_DATETIME_NAT is used as error condition, so initialize it to
something else.
