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.

1. Use CMake FindLAPACK and FindBLAS Modules.
2. Remove SEARCH_HEADERS and SEARCH_LIBS and replace them with
CMAKE variables. This leads to simplification of the FIND_LIBRARY
and FIND_PATH calls.
3. Make miniglog a fallback when glog is not present and the
user indicates MINIGLOG=OFF.
4. Add time.h to miniglog.
5. Remove shared library building.

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.

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.
