Michael Davidsaver e843779555 New array API for PVValueArray using shared_vector<T> ...

* In PVScalarArray

Add methods assign, getAs/putFrom, and copyOut/copyIn to allow get/put
with implicit convert.

assign() copys on PVScalarArray to another converting as necessary.
If the types do not match then an allocate and convert is done.

getAs/putFrom work with shared_vector<T> and can avoid a allocate
and convert operation if the types match.

copyOut/copyIn use plain C arrays will do either a copy if the types
match, and a convert otherwise.  No allocation is performed.

* In PVValueArray<T>

All array operations re-implemented in terms of
two virtual methods

  virtual const shared_vector<T>& viewUnsafe() const;
  virtual void swap(shared_vector<T>&);

Some convienence methods are also included:

  shared_vector<const T> view() const
  shared_vector<T> take()
  shared_vector<T> reuse()

Deprecate get(...), put(...), and shareData(...)

Remove getVector() and getSharedVector()

Adjust DefaultPVArray accordingly
