1. Add a version history
2. Update copyright years across the code base
3. Run format_all.sh
4. Update version strings from 2.1.0 to 2.2.0 in the docs and
elsewhere.

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.

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.

Applied changes correspond to clang-tidy fixes
stemming from the modernize-use-equals-default check.

- 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

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.

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.
