    Relax the tolerance in QuaternionParameterizationTestHelper.
    
    This commit relaxes the tolerance value for comparing between the actual
    local matrix and the expected local matrix. Without this fix,
    EigenQuaternionParameterization.ZeroTest could fail as the difference
    exactly matches the value of std::numeric_limits<double>::epsilon().

    Relaxing Jacobian matching in Gradient Checker test.
    
    Any result of an arithmetic operation on floating-point matrices
    should never be checked for strict equality with some expected
    value, due to limited floating point precision on different machines.
    This fixes some occurences of exact checks in the gradient checker
    unit test that were causing problems on some platforms.

    Allow SubsetParameterization to hold all parameters constant
    
    1. SubsetParameterization can now be constructed such that all
    parameters are constant. This is required for it be used as part
    of a ProductParameterization to hold a part of parameter block
    constant. For example, a parameter block consisting of a rotation
    as a quaternion and a translation vector can now have a local
    parameterization where the translation part is constant and the
    quaternion part has a QuaternionParameterization associated with it.
    
    2. The check for the tangent space of a parameterization being
    positive dimensional. We were not doing this check up till now
    and the user could accidentally create parameterizations like this
    and create a problem for themselves. This will ensure that even
    though one can construct a SubsetParameterization where all
    parameters are constant, you cannot actually use it as a local
    parameterization for an entire parameter block. Which is how
    it was before, but the check was inside the SubsetParameterization
    constructor.
    
    3. Added more tests and refactored existing tests to be more
    granular.

    Remove two DCHECKs from CubicHermiteSpline.
    
    They were present as debugging checks but were causing problems
    with the build on 32bit i386 due to numerical cancellation issues,
    where x ~ -epsilon.
    
    Removing these checks only changes the behaviour in Debug mode.
    We are already handling such small negative numbers in production
    if they occur. All that this change does is to remove the crash.

    Gradient checker multithreading bugfix.
    
    This is a follow-up on c/7470. GradientCheckingCostFunction calls
    callback_->SetGradientErrorDetected() in its Evaluate method,
    which will run in multiple threads simultaneously when enabling
    this option in the solver. Thus, the string append operation
    inside that method has to be protected by a mutex.

    Use ProductParameterization in bundle_adjuster.cc
    
    Previously, when using a quaternion to parameterize the camera
    orientation, the camera parameter block was split into two
    parameter blocks. One for the rotation and another for the
    translation and intrinsics. This was to enable the use of the
    Quaternion parameterization.
    
    Now that we have a ProductParameterization which allows us
    to compose multiple parameterizations, this is no longer needed
    and we use a size 10 parameter block instead.
    
    This leads to a more than 2x improvements in the linear solver time.

    Gradient checking cleanup and local parameterization bugfix
    
    Change the Ceres gradient checking API to make is useful for
    unit testing, clean up code duplication and fix interaction between
    gradient checking and local parameterizations.
    
    There were two gradient checking implementations, one being used
    when using the check_gradients flag in the Solver, the other
    being a standalone class. The standalone version was restricted
    to cost functions with fixed parameter sizes at compile time, which
    is being lifted here. This enables it to be used inside the
    GradientCheckingCostFunction as well.
    
    In addition, this installs new hooks in the Solver to ensure
    that Solve will fail if any incorrect gradients are detected. This
    way, you can set the check_gradient flags to true and detect
    errors in an automated way, instead of just printing error information
    to the log. The error log is now also returned in the Solver summary
    instead of being printed directly. The user can then decide what to
    do with it. The existing hooks for user callbacks are used for
    this purpose to keep the internal API changes minimal and non-invasive.
    
    The last and biggest change is the way the the interaction between
    local parameterizations and the gradient checker works. Before,
    local parameterizations would be ignored by the checker. However,
    if a cost function does not compute its Jacobian along the null
    space of the local parameterization, this wil not have any effect
    on the solver, but would result in a gradient checker error.
    With this change, the Jacobians are multiplied by the Jacobians
    of the respective local parameterization and thus being compared
    in the tangent space only.
    
    The typical use case for this are quaternion parameters, where
    a cost function will typically assume that the quaternion is
    always normalized, skipping the correct computation of the Jacobian
    along the normal to save computation cost.

    Use _j[0,1,n]() Bessel functions on MSVC to avoid deprecation errors.
    
    - Microsoft deprecated the POSIX Bessel functions: j[0,1,n]() in favour
      of _j[0,1,n](), it appears since at least MSVC 2005:
      https://msdn.microsoft.com/en-us/library/ms235384(v=vs.100).aspx.
    - As this occurs in jet.h (templated public header), although Ceres
      suppresses the warning when it itself is built (to suppress a warning
      about the insecurity of using std::copy), it will crop up again in
      client code (without this fix) unless it is explicitly suppressed
      there also.

    Fix step norm evaluation in LineSearchMinimizer
    
    TrustRegionMinimizer evaluates the size of the step
    taken in the ambient space, where as the LineSearchMinimizer
    was using the norm in the tangent space. This change fixes
    this discrepancy.

    Remove use of -Werror when compiling Ceres.
    
    - As noted in Issue #193 (in that case for GCC 6), Ceres' use of -Werror
      when compiling on *nix can prevent compilation on new compilers that
      add new warnings and there is an inevitable delay between new compiler
      versions and Ceres versions.
    - Removing the explicit use of -Werror, and relying on indirect
      verification by maintainers should fix build issues for Ceres releases
      on newer compilers.

    Report Ceres compile options as components in find_package().
    
    - Users can now specify particular components from Ceres, such as
      SuiteSparse support) that must be present in a detected version of
      Ceres in order for it to be reported as found by find_package().
    - This allows users to specify for example that they require a version
      of Ceres with SuiteSparse support at configure time, rather than
      finding out only at run time that Ceres was not compiled with the
      options they require.
    - The list of available components are built directly from the Ceres
      compile options.
    - The meta-module SparseLinearAlgebraLibrary is present if at least
      one sparse linear algebra backend is available.

    Fix install path for CeresConfig.cmake to be architecture-aware.
    
    - Previously we were auto-detecting a "64" suffix for the install path
      for the Ceres library on non-Debian/Arch Linux distributions, but
      we were installing CeresConfig.cmake to an architecture independent
      location.
    - We now install CeresConfig.cmake to lib${LIB_SUFFIX}/cmake/Ceres.
    - Also make LIB_SUFFIX visible to the user in the CMake GUI s/t they can
      easily override the auto-detected value if desired.
    - Reported by jpgr87@gmail.com as Issue #194.
