Sameer Agarwal 0a53aa9054 Take abseil as a dependency
1. Add abseil-cpp as a submodule. We are tracking the latest LTS
release, which is lts_2024_01_16.
2. Replace glog/gflags with absl::log and absl::flags.
3. Remove miniglog
4. Also take a whack at making the bazel build work with
   abseil-cpp and gtest.

There are a number of TODOs in this CL that still need to be resolved.

Sergiu Deitsch 91773746be Simplify instantiation of cost functions and their functors
If arguments are passed to a cost function that can be used to construct
the functor, the latter will be instantiated by the cost function using
std::make_unique to ensure exception safety. This not only avoids static
analysis warnings caused by calling new but also spelling the cost
functor type name multiple times.

Also expand deduction guides for instantiating
Dynamic(Auto|Numeric)DiffCostFunction from std::unique_ptr enabled
constructor overloads.

Finally, make CostFunction default move constructible and assignable but
only through derived classes. This in turn allows derived classes to be
movable without relying on custom implementations of corresponding
operators.

Nikolaus Demmel 7b6b2491cc fix formatting for examples
This is mostly just applying the existing clang format config, except:
- Use NOLINT on overlong comment lines.
- Wrap some sections in 'clang-format off' / 'clang format on'.
- Manually split or join some multi-line strings.

Sergey Sharybin 54ba6c27b5 Fix missing declaration warnings in Ceres code
This commit includes the following:

- Changes to CMake to make it safer to see which compiler flags are supported,
  so this way we do not need to worry about version checks in CMake.

- Unix platforms (which includes both Linux and Apple as far as i can tell)
  will now enable -Wmissing-declarations warning for the whole Ceres.

- Changes in all sources to solve missing declaration warning. In most cases
  it was either matter of using static qualifier or moving functions to an
  anonymous namespace.

  In one case the function got removed, since it seems to be unused.

  Additionally, in slam examples there was a non-inlined function implementation
  in a header, which is a direct way to cause linking errors if other .cc file
  will include that helper header.

- All third party sources (which is currently only gmock) has this extra
  paranoid warning disabled.

This warning is important in the following cases:

- Detect helper functions which are not needed anymore.
- Avoid unnoticed pollution of namespace.
- Avoid bad level calls.
- Avoid missing updates in header files after changes in implementation file.
- Helps integrating Ceres into software where paranoid warnings are important.

Sameer Agarwal d05515b3eb Remove spurious conversion from doubles to Jets.
Binary operations between Jets and doubles are well defined
and should not require an explicit conversion to Jets to work.
This was an oversight earlier and lead to overzealous conversions
all over our in our example code.

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.

Richard Stebbing 32530788d0 Add dynamic_sparsity option.
The standard sparse normal Cholesky solver assumes a fixed
sparsity pattern which is useful for a large number of problems
presented to Ceres. However, some problems are symbolically dense
but numerically sparse i.e. each residual is a function of a
large number of parameters but at any given state the residual
only depends on a sparse subset of them. For these class of
problems it is faster to re-analyse the sparsity pattern of the
jacobian at each iteration of the non-linear optimisation instead
of including all of the zero entries in the step computation.

The proposed solution adds the dynamic_sparsity option which can
be used with SPARSE_NORMAL_CHOLESKY. A
DynamicCompressedRowSparseMatrix type (which extends
CompressedRowSparseMatrix) has been introduced which allows
dynamic addition and removal of elements. A Finalize method is
provided which then consolidates the matrix so that it can be
used in place of a regular CompressedRowSparseMatrix. An
associated jacobian writer has also been provided.

Changes that were required to make this extension were adding the
SetMaxNumNonZeros method to CompressedRowSparseMatrix and adding
a JacobianFinalizer template parameter to the ProgramEvaluator.
