ENH: Add `raw`, `reduced`, `complete` modes to qr factorization.
If K = min(M, N) where the matrix to be factored has dimensions MxN,
then
'reduced' : returns q, r with dimensions (M, K), (K, N) (default)
'complete' : returns q, r with dimensions (M, M), (M, N)
'r' : returns r only with dimensions (K, N)
'raw' : returns h, tau with dimensions (N, M), (K,)
'full' : alias of 'reduced', deprecated
'economic' : returns h from 'raw', deprecated.
The options 'reduced', 'complete, and 'raw' are new. The default is
'reduced' and to maintain backward compatibility with earlier versions
of numpy both it and the old default 'full' can be omitted. Note that
array `h` returned in 'raw' mode is transposed for calling Fortran. Both
the 'full' and 'economic' modes are deprecated. For backwards
compatibility the modes 'full', 'economic' may be passed using only the
first letter but all others must be spelled out.
