[foreign-memaccess] [Rev 02] RFR: JDK-8241866:Add API to reshape sequence layouts

[Maurizio Cimadamore]

> https://docs.scipy.org/doc/numpy/reference/generated/numpy.reshape.html
> 
> As in Python, clients can use _at most_ one `-1` dimension value, and that dimension value will be inferred by
> remaining dimensions.
> The changes also add the `flatten` method, which does the opposite - e.g. take a sequence layout, whose element layout
> could be other nested sequence layouts and flatten everything into an outermost sequence layout (where element count is
> adjusted as needed).  These routines are fairly general and helpful and I found myself in need for something similar
> when writing code doing parallel processing of memory segments, but there are many other possible use cases.
