6519388f5c Build /permissive- under VS2017
Building with the (VS2017) /permissive- flag puts the compiler into
stricter standards-compliant mode.  It shouldn't cause the compiler to
work differently--it just disallows some non-conforming code--so should
be perfectly fine for the test suite under all VS2017 builds.

This commit also fixes one failure under non-permissive mode.

a28393cf7b Fix 2D Nx1/1xN inputs to eigen dense vector args
This fixes a bug introduced in b68959e822
when passing in a two-dimensional, but conformable, array as the value
for a compile-time Eigen vector (such as VectorXd or RowVectorXd).  The
commit switched to using numpy to copy into the eigen data, but this
broke the described case because numpy refuses to broadcast a (N,1)
into a (N).

This commit fixes it by squeezing the input array whenever the output
array is 1-dimensional, which will let the problematic case through.
(This shouldn't squeeze inappropriately as dimension compatibility is
already checked for conformability before getting to the copy code).

fe1266e069 Fix char & arguments being non-bindable
This changes the caster to return a reference to a (new) local `CharT`
type caster member so that binding lvalue-reference char arguments
works (currently it results in a compilation failure).

Fixes #1116

1caeb8d789 Fix Travis style/docs/pip build
When Travis changes their default Python 3.x, it breaks any hardcoded
version selection. Fix: make pyenv activate everything (2.7, 3.x) and
use whichever Python 3.x is on by default.

2b4477eb65 Make TypeErrors more informative when an optional header is missing
E.g. trying to convert a `list` to a `std::vector<int>` without
including <pybind11/stl.h> will now raise an error with a note that
suggests checking the headers.

The note is only appended if `std::` is found in the function
signature. This should only be the case when a header is missing.
E.g. when stl.h is included, the signature would contain `List[int]`
instead of `std::vector<int>` while using stl_bind.h would produce
something like `MyVector`. Similarly for `std::map`/`Dict`, `complex`,
`std::function`/`Callable`, etc.

There's a possibility for false positives, but it's pretty low.

3c4933cb50 Fix STL casters for containers with proxies (regression)
To avoid an ODR violation in the test suite while testing

the `py::bind_vector<std::vector<bool>>` test is moved to
the secondary module (which does not include `stl.h`).

b7c98d21e1 Speed up Travis CI build (#1056)
* Update Python 3 osx image to xcode8.3 to speed up brew install. 
  The Python 2 osx image remains xcode7.3.

* Have one osx config run in debug mode to improve coverage.

* Only run CMake build tests on two configs to speed up overall build.

  The CMake tests take ~30 seconds on each configuration, but we really 
  only need to them to run on two: one on Linux and one on macOS. This
  mirrors the recent change on AppVeyor.

* Merge the style/docs/pip tests with the barebones build.

* Merge 32-bit and CMake install configurations.

  This removes clang 3.9 from testing, but there are already 3 other clang 
  versions being tested on Travis and the new xcode8.3 image should be 
  close to clang 3.9.

There are two separate additions:

2. `.def(hash(py::self))` registers the hash function defined by
   `std::hash<T>` as the Python hash function.

39fd6a9463 Reduce binary size overhead of new-style constructors
The lookup of the `self` type and value pointer are moved out of
template code and into `dispatcher`. This brings down the binary
size of constructors back to the level of the old placement-new
approach. (It also avoids a second lookup for `init_instance`.)

With this implementation, mixing old- and new-style constructors
in the same overload set may result in some runtime overhead for
temporary allocations/deallocations, but this should be fine as
old style constructors are phased out.

c14c2762f6 Address reference leak issue (fixes #1029)
Creating an instance of of a pybind11-bound type caused a reference leak in the
associated Python type object, which could prevent these from being collected
upon interpreter shutdown. This commit fixes that issue for all types that are
defined in a scope (e.g. a module). Unscoped anonymous types (e.g. custom
iterator types) always retain a positive reference count to prevent their
collection.

1913f252d3 Fix setup.py detail headers and add pip install tests to Travis
The default `install_headers` from `distutils` flattens all the headers
into a single directory -- `detail` subdirectory was lost. This commit
fixes this by overriding the setup with a custom header installer.

Tests are added to Travis to make sure `setup.py sdist` and `pip install`
do not miss any headers and that the directory structure is preserved.
