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.

- Previously if miniglog was being used (on a non-Android system), we
compiled it into a separate library, against which Ceres then linked.
- This was unsatisfactory as it required miniglog being built as a
static library when building Ceres as a Windows DLL, because miniglog
did not use the dllexport/dllimport statements, whilst for other
platforms when building Ceres as a shared library, miniglog needed to
be compiled as a shared library.
- We now compile miniglog into Ceres on all platforms, not just on
Android.
- miniglog now uses the CERES_EXPORT macro to support Windows DLLs.
This means that miniglog now depends on Ceres' internal/port.h (and
thus internal/config.h) which define the CERES_EXPORT macro and
control its behaviour respectively.
- miniglog now also uses localtime_s, not localtime on Windows.

Add Minimizer::Options::is_silent which allows the user
to turn off the logging inside the minimizer completely.
In particularly this is used for silencing the logging
when inner iterations are used.
Add VLOG_IF to miniglog.

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 change adds several of the pieces needed to build Ceres on
Android. The port is incomplete, since GFlags doesn't build which
causes the tests to not build. However, simple_bundle_adjuster
builds and runs on the phone.
Thanks to Scott Ettinger for the original version of the minimal
GLog implementation which made this port possible. The Ceres logs
go to the various Android logging levels, as documented in
miniglog/glog/logging.h.
To control the Android build, this adds a new CMake build option:
-DBUILD_ANDROID=ON/OFF
However, users may not want to set this manually, and should
instead run the script found in android/build_android.sh. The
script calls the NDK to make a standalone toolchain, downloads the
android-cmake toolchain, then configures CMake to cross-compile
Ceres to Android.
Note: At time of writing, the android-cmake toolchain that the
script downloads from Google Code doesn't work with the latest
Jellybean NDK. It's possible to manually hack the toolchain file
to make it build by setting the compiler version and manually
setting the path to the STL includes. I don't yet have a patch
suitable for upstreaming to http://android-cmake.googlecode.com.
