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.

Apple annoyingly claims that dsyrk_ is a private API, and rejects
submissions to the Apple Store that include this symbol.

Also change ifdef -> ifndef in blas.cc

This will allow iOS users not to suffer Apple's
idiotic AppStore approval process.

- Ensure that, as in the preprocessor, we force num_threads to be 1
  if Ceres was compiled without OpenMP to prevent a CHECK() failure
  in internal code.

Change-Id: I49d7bdeff81e5bb24aaaa3945018d9d012cd9df9

Removes the CHECK-fail for num_threads > 1 when
OpenMP is not detected

This has a measurable impact on interpolation performance.

Also remove an accidentally named enum with an anonymous enum.

The key change is that there is a new layer of abstract,
a Array object that the interpolator depends on.

The Array provides a one dimension or two dimensional
array like interface independent of the underlying representation
of the data.

Also included here is support for vector valued functions.

Make the definition of CERES_NO_THREADS conditional on the presence
of the CERES_HAVE_PTHREADS define.

This allows the user to enable threading in ceres using a combination
of CERES_EXTRA_DEFINES and linker flags which they need to do in
their app.

Delete code needed by old versions of the NDK. We do not build
with these versions of the NDK and do not use STLPort anymore.

Due to floating point and conditioning issues, a system
matrix which is guaranteed to be PSD in exact arithmetic
can appear indefinite to the ConjugateGradientsSolver.

Previously, x'Ax <= 0, the solver returned with numerical
failure. Which the trust region solver will treat as a failed
solve.

But, more general truncated Newton when they encounter indefiniteness
use the step computed till that point instead of declaring failure.

This changes does this and adds a bit more logging.

The example code for DynamicNumericDiffCostFunction and
DynamicAutoDiffCostFunction in the documentation was
allocating the cost function objects on the stack rather
than the heap.

Example code demonstrates how a sampled function can be
minimized. Also, in the process uncovered some deficiencies
in the CubicInterpolator and BicubicInterpolator interfaces and
fixed them.

This bi-cubic interpolation implementation is based
on the cubic convolution algorithm of keys, which allows
us to implement a bi-cubic spline like interpolation scheme
using five one dimensional cubic spline operations.

error message with more context.

- Results of find_program() are by default visible in the CMake GUI
  (cache), but the user has no reason to care in general about the
  location of the Homebrew executable detected.
- Note it is still available in the GUI, but only via toggling to the
  advanced display.
