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.

Keir Mierle 6e8bd501b2 Extend the C API to support loss functions
This extends the C API to support loss functions. Both
user-supplied cost functions as well as the stock Ceres cost
functions (Cauchy, Huber, etc) are supported. In addition, this
adds a simple unit test for the C API.

Supporting loss functions required changing the signature of the
ceres_add_residual_block() function to also take a thunk for the
loss function.

Sergey Sharybin 2a3827e13d Compilation error fixes
- In C you're not allowed to define variables in the middle
  of the block. This was violated in curve_fitting.c by
  calling ceres_init() in the beginning of main() and declaring
  variables later.

- Also ifdef-ed suitesparse stuff in covariance estimation module.
  This solves compilation error when you don't have suitesparse
  compiled/installed.

Keir Mierle f956615ef1 Proof of concept C API for Ceres
This introduces a simple C API for a subset of Ceres. This opens the door to
using languages like Python to call Ceres, since it is much easier to bind to C
than it is to bind to C++. It will mean giving up the native Ceres autodiff.

The implementation in this patch does not attempt to do everything but is only
just enough to get started. Subsequent patches will increase the surface area
of Ceres that is covered by the C API.
