Sameer Agarwal 19ab2c1793 BlockRandomAccessMatrix Refactor
1. Add threading to all three subclasses of BlockRandomAccessMatrix.
   i.e. BlockRandomAccessDenseMatrix, BlockRandomAccessSparseMatrix
   and BlockRandomAccessDenseMatrix.

   For BlockRandomAccessDenseMatrix and BlockRandomAccessSparseMatrix
   this just means SetZero is parallelized. Which by itself is no
   big deal, but by doing so, the constructor for all three subclasses
   become uniform.

   BlockRandomAccessSparseMatrix::SymmetricRightMultiplyAndAccumulate
   maybe threaded in the future if needed.

   BlockRandomAccessDiagonalMatrix is the biggest beneficiary. SetZero
   Invert and RightMultiplyAndAccumulate are all threaded now.

2. Change the storage in BlockRandomAccessDiagonalMatrix from
   TripletSparseMatrix to CompressedRowSparseMatrix. This has no
   performance implications since we do not really use the capabilities
   of the underlying matrix indexing representation. This is a forward
   looking change when we decide to transfer this matrix to the GPU,
   a CompressedRowSparseMatrix will save on a data conversion.

3. Use std::unique_ptr as needed and eliminate the need for custom
   destructors.

4. Modify CompressedRowSparseMatrix::CreateBlockDiagonalMatrix to
   take a nullptr as the data vector.

Sameer Agarwal f86a3bdbea Unify Block handling across matrix types
Previously some matrices used Block to keep track of
row/column block sizes and some would just use ints, and
then compute the position of each row and column from it.

By uniformly using Block everywhere, we reduce duplicate
computation and data copies.

I also cleaned up a bunch of c++17 related stuff as I edited
these files.

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 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

Sameer Agarwal 2ffddaccfe Use override & final instead of just using virtual.
This is safer than using virtual and this lead to a minor
bug fixes.

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.

Keir Mierle 7492b0d8de Update copyright headers with new year and URL
Since Ceres is moving to using GitHub for issues, and the Google
Code URL in the current copyright header will soon become invalid,
update all the headers.

Sameer Agarwal bcc865f81c Remove using namespace std;
For historical reasons we had a "using namespace std;" in port.h. This
is generally a bad idea. So removing it and along the way doing a bunch
of cpplint cleanup.
