Add -Wdeprecated to test suite and fix associated warnings (#1191)
This commit turns on `-Wdeprecated` in the test suite and fixes several associated deprecation warnings that show up as a result: - in C++17 `static constexpr` members are implicitly inline; our redeclaration (needed for C++11/14) is deprecated in C++17. - various test suite classes have destructors and rely on implicit copy constructors, but implicit copy constructor definitions when a user-declared destructor is present was deprecated in C++11. - Eigen also has various implicit copy constructors, so just disable `-Wdeprecated` in `eigen.h`. |

Reimplement py::init<...> to use common factory code
This reimplements the py::init<...> implementations using the various functions added to support `py::init(...)`, and moves the implementing structs into `detail/init.h` from `pybind11.h`. It doesn't simply use a factory directly, as this is a very common case and implementation without an extra lambda call is a small but useful optimization. This, combined with the previous lazy initialization, also avoids needing placement new for `py::init<...>()` construction: such construction now occurs via an ordinary `new Type(...)`. A consequence of this is that it also fixes a potential bug when using multiple inheritance from Python: it was very easy to write classes that double-initialize an existing instance which had the potential to leak for non-pod classes. With the new implementation, an attempt to call `__init__` on an already-initialized object is now ignored. (This was already done in the previous commit for factory constructors). This change exposed a few warnings (fixed here) from deleting a pointer to a base class with virtual functions but without a virtual destructor. These look like legitimate warnings that we shouldn't suppress; this adds virtual destructors to the appropriate classes. |

Allow binding factory functions as constructors
This allows you to use:
cls.def(py::init(&factory_function));
where `factory_function` returns a pointer, holder, or value of the
class type (or a derived type). Various compile-time checks
(static_asserts) are performed to ensure the function is valid, and
various run-time type checks where necessary.
Some other details of this feature:
- The `py::init` name doesn't conflict with the templated no-argument
`py::init<...>()`, but keeps the naming consistent: the existing
templated, no-argument one wraps constructors, the no-template,
function-argument one wraps factory functions.
- If returning a CppClass (whether by value or pointer) when an CppAlias
is required (i.e. python-side inheritance and a declared alias), a
dynamic_cast to the alias is attempted (for the pointer version); if
it fails, or if returned by value, an Alias(Class &&) constructor
is invoked. If this constructor doesn't exist, a runtime error occurs.
- for holder returns when an alias is required, we try a dynamic_cast of
the wrapped pointer to the alias to see if it is already an alias
instance; if it isn't, we raise an error.
- `py::init(class_factory, alias_factory)` is also available that takes
two factories: the first is called when an alias is not needed, the
second when it is.
- Reimplement factory instance clearing. The previous implementation
failed under python-side multiple inheritance: *each* inherited
type's factory init would clear the instance instead of only setting
its own type value. The new implementation here clears just the
relevant value pointer.
- dealloc is updated to explicitly set the leftover value pointer to
nullptr and the `holder_constructed` flag to false so that it can be
used to clear preallocated value without needing to rebuild the
instance internals data.
- Added various tests to test out new allocation/deallocation code.
- With preallocation now done lazily, init factory holders can
completely avoid the extra overhead of needing an extra
allocation/deallocation.
- Updated documentation to make factory constructors the default
advanced constructor style.
- If an `__init__` is called a second time, we have two choices: we can
throw away the first instance, replacing it with the second; or we can
ignore the second call. The latter is slightly easier, so do that.
