Joydeep Biswas 8e08421628 Add support for dense CUDA solvers #3
1. Add CUDA initialization and cleanup management to the
   ContextImpl object. The ContextImpl is now solely responsible
   for managing CUDA-related resources.
2. All CUDA dense solvers now use lazy CUDA initialization
   via the ContextImpl object.

Sergiu Deitsch f90833f5fa Simplify symbol export
Currently, the logic for exporting symbols is rather complicated: when
tests are enabled internal symbols are exported in addition to the
public symbols. Such logic causes several problems. (1) Test binaries
link against a Ceres build that is different from the final release
since fewer optimizations are applied if more symbols are exported. (2)
Also, some toolchains hide symbols by default breaking the existing
logic eventually causing linker errors.

Since internal symbols are not intended to be used outside of the
project, we can compile them into object files and use exactly the same
binary code both for the final build and the tests without relying on
conditionals.

By default, all symbols are now hidden unless annotated as public.
Internal symbols are explicitly marked as not being exported in case
users chose not to hide symbols by default.

Sergiu Deitsch c14f360e63 Drop trivial special members
Do not define trivial constructors or destructors unless necessary
(e.g., for implementing pimpl) following the rule of zero. Define
virtual base class destructors out-of-line to avoid emitting vtables in
every translation unit.

Sergiu Deitsch a35bd1bf90 Use = default for trivial special members
Applied changes correspond to clang-tidy fixes
stemming from the modernize-use-equals-default check.

Sergiu Deitsch 484d3414e4 Replace virtual keyword by override
virtual can be ambiguous. Applied changes correspond to clang-tidy fixes
stemming from the modernize-use-override check.

Nikolaus Demmel 7b8f675bfd fix formatting for (non-generated) internal source files
- Change formatting standard to Cpp11. Main difference is not having
  the space between two closing >> for nested templates. We don't
  choose c++14, because older versions of clang-format (version 9
  and earlier) don't know this value yet, and it doesn't make a
  difference in the formatting.
- Apply clang-format to all (non generated) internal source files.
- Manually fix some code sections (clang-format on/off) and c-strings
- Exclude some embedded external files with very different formatting
  (gtest/gmock)
- Add script to format all source files

Alex Stewart 7ef83e0759 Update minimum required C++ version for Ceres to C++14
- Removes all workarounds for pre-C++14 versions
- Removes '11' qualifier from C++ threading option and associated
  defines.
- Fix missing inclusion of 'Multithreading' in reported Ceres components
  when C++ threading model is enabled.
- Update Sphinx documentation to specify C++14 as minimum requirement.

Sameer Agarwal 31f24521cc Deprecate macros.h and fpclassify.h
1. Replace CERES_DISALLOW_* with explicitly deleted constructors.
2. Replace use of CERES_ARRAY_SIZE and stack allocated arrays
   with std::vector.
3. Move CERES_ALIGN_* macros into manual_constructor.h, which is
   the one place they are used and will be deprecated along with that
   file.
4. Introduce isnan,isnormal,isinf and isfinite for Jets.
5. Replace IsNormal,IsFinite,IsNaN and IsInfinite with corresponding
   c++11 function calls.

Mike Vitus f408f89e8b Adds a Ceres Context structure.
A Ceres Context holds common global state that can be re-used within
Ceres.  The Context current contains a thread pool if compiling with
C++11 threading support.  Threads are expensive to create and destroy so
it is good to maintain across multiple Ceres solves.

Tested by compiling with and without TBB support and ran unit tests. Ran
bazel as well.
