Cleanup of file-scoped and globally-scoped warning suppression pragmas across pybind11 header files. (#3201)

* Removing all MSVC C4127 warning suppression pragmas.

* Removing MSVC /WX (WERROR). To get a full list of all warnings.

* Inserting PYBIND11_SILENCE_MSVC_C4127. Changing one runtime if to #if.

* Changing PYBIND11_SILENCE_MSVC_C4127 macro to use absolute namespace (for use outside pybind11 include directory).

* Restoring MSVC /WX (WERROR).

* Removing globally-scoped suppression for clang -Wunsequenced. Based on an experiment under PR #3202 it is obsolete and can simply be removed.

* Removing pragma for GCC -Wattributes, fixing forward declarations.

* Introducing PYBIND11_NOINLINE_FWD to deal with CUDA, GCC7, GCC8.

* Updating PYBIND11_NOINLINE_DCL in Doxyfile.

* Removing code accidentally left in (was for experimentation only).

* Removing one-time-test define.

* Removing PYBIND11_NOINLINE_FWD macro (after learning that it makes no sense).

* Testing with PYBIND11_NOINLINE_DISABLED. Minor non-functional enhancements.

* Removing #define PYBIND11_NOINLINE_DISABLED (test was successful).

* Removing PYBIND11_NOINLINE_FORCED and enhancing comments for PYBIND11_NOINLINE.

* WIP stripping back

* Making -Wattributes pragma in pybind11 specific to GCC7, GCC8, CUDA.

* See if existing test triggers for a const type.

* Add tests.

* Fix test.

* Remove experiment.

* Reformat.

* More tests, checks run.

* Adding `test_fmt_desc_` prefix to new test functions.

* Using pytest.mark.parametrize to 1. condense test; 2. exercise all functions even if one fails; 3. be less platform-specific (e.g. C++ float is not necessarily float32).

When the user defines _GLIBCXX_USE_CXX11_ABI=0 to force the pre-c++11 ABI, numpy.h assumes that is_trivially_copyable is available.
It is not necessarily the case. This patch uses clang's feature detection instead.
The workaround is for certain libstdc++ versions, so the test should target these particular versions.

* [dtype]: add type() method to access type attribute of PyArray_Descr (eq. to dtype.char in Python)

* [dtype] change type() name method to char_() to be compliant with Python numpy interface

* [dtype] fix by pre-commit

* [dtype] Change comments and solutions format for test

* Clarify documentation and move note about dtype.char vs PyArray_Descr::type to a plain, non-doxygen comment

* Fix and extend tests

* Fix the supposedly fixed tests

* Fix the fixed tests again

* tests: New test for ctypes buffers (pybind#2502)

* fix: fix buffer_info segfault on views with no stride (pybind11#2502)

* Explicit conversions in buffer_info to make clang happy (pybind#2502)

* Another explicit cast in buffer_info constructor for clang (pybind#2502)

* Simpler implementation of buffer_info constructor from Py_buffer.

* Move test_ctypes_buffer into test_buffers

* Comment on why view->strides may be NULL (and fix some whitespace)

* Use c_strides() instead of zero when view->strides is NULL.

c_strides and f_strides are moved from numpy.h (py::array)
to buffer_info.h (py::detail) so they can be used from the
buffer_info Py_buffer constructor.

* Increase ctypes buffer test coverage in test_buffers.

* Split ctypes tests and skip one which is broken in PyPy2.

* WIP: module -> module_ without typedef

* refactor: allow py::module to work again

* Allow function/functor passed to py::vectorize to return void

* Stealing @sizmailov's test and fixing unused argument warning

* Add missing std::move()

RVO doesn't work here because function return type is different from
actual returned type

* remove extra EOL

* docs: add a few details

* chore: pre-commit autoupdate

* Remove array_iterator, array_begin, and array_end (in detail namespace)

Add unchecked_reference::operator() and operator[] to overload resolution of unchecked_mutable_reference (#2514)

Support C++20. For backwards compatibility, we provide an alias for the old name.
This change is necessary to easily avoid errors when a compiler thinks
`module` is used as a keyword.

Stop py::array_t arguments from accepting arrays that do not match the C- or F-contiguity flags (#2484)

* Stop py::array_t arguments from accepting arrays that do not match the C- or F-contiguity flags

* Add trivially-contiguous arrays to the tests

* fix: support nvcc and test

* fixup! fix: support nvcc and test

* docs: mention what compilers fail

* fix: much simpler logic

* refactor: slightly faster / clearer

* fix: add missing signature

* fix: add to array_t too

* Change NAMESPACE_BEGIN and NAMESPACE_END macros into PYBIND11_NAMESPACE_BEGIN and PYBIND11_NAMESPACE_END

* Fix sudden HomeBrew 'python not installed' error

* Sweep difference in 'Class.__init__() must be called when overriding __init__' error message between CPython and PyPy under the rug

* Homebrew updated to 3.8 yesterday.

This reverts commit 61e4f118.

PyArray_DescrFromType returns a new reference, not borrowed one

Test for dtype checks now succeed without warnings

* Test dtype field order in numpy dtype tests

When running tests with NumPy 1.14 or later this test exposes the
"invalid buffer descriptor" error reported in #1274.

* Create dtype_ptr with ordered fields
