Dmitriy Korchemkin 6685e629f9 AddBlockStructureTranspose to BlockSparseMatrix
Add structure of transposed matrix to BlockSparseMatrix

Number of non-zero values per row block and cumulative non-zero
values count are maintained for transposed structure

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.

Joydeep Biswas c9d2ec8a9f Updates to sparse block matrix structures to support new
sparse linear solvers.

* Add methods to convert TripletSparseMatrix and BlockSparseMatrix to
  CRSMatrix structure.
* Added tests for conversion of TripletSparseMatrix and BlockSparseMatrix
  to CRSMatrix structure.
* Added documentation on the BlockSparseMatrix structure.

Sergiu Deitsch c8658c8992 Modernize more
Apply clang-tidy Google and modernize fixes without trailing return type
using:

$ clang-tidy -p <build-dir> \
  -checks='-*,google-*,modernize-*,-modernize-use-trailing-return-type' {} -fix

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 a35bd1bf90 Use = default for trivial special members
Applied changes correspond to clang-tidy fixes
stemming from the modernize-use-equals-default 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 e82e128344 Deprecate integral_types.h
This header defined integral types in the pre-C++11 days, and can
be replaced with <cstdint> and the types defined therein.

Also remove a shallow (and incorrect) typedef in include/ceres/types.h

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.

Sameer Agarwal 85561eee95 Use int32 for parameter block sizes.
CostFunction now uses int32 instead of int16
to store the size of its parameter blocks.

This is an API breaking change.
