The schur eliminator treats rows with e blocks and row with
no e blocks separately. The template specialization logic only
applies to the rows with e blocks.
So, in cases where the rows with e-blocks have a fixed size f-block
but the rows without e-blocks have f-blocks of varying sizes,
DetectStructure will return a static f-block size, but we need to be
careful that we do not blindly use that static f-block size everywhere.
This patch fixes a bug where such care was not being taken, where
it was assumed that the static f-block size could be assumed for all
f-block sizes.
A new test is added, which triggers an exception in debug mode. In
release mode this error does not present itself, due to a peculiarity
of the way Eigen works.
Thanks to Werner Trobin for reporting this bug.

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.

This support was broken due to the TrustRegionMinimizer refactoring.
It is now enabled again, with the responsibilty for dumping the
problem shifted to the individual TrustRegionStrategy.
There is however one wrinkle, which is perhaps an indication of
poor design to start with. The LinearLeastSquaresProblemProto
carries in it num_eliminate_blocks, something which does not
exist anymore. More importantly, the TrustRegionStrategy does not
have access to this quantity anymore.
Dealing with this will be the subject of a future change.

1. Make the mechanism for writing problems to disk, generic and
controllable using an enum DumpType visible in the API.
2. Instead of single file containing protocol buffers, now matrices can
be written in a matlab/octave friendly format. This is now the default.
3. The support for writing problems to disk is moved into
linear_least_squares_problem.cc/h
4. SparseMatrix now has a ToTextFile virtual method which is
implemented by each of its subclasses to write a (i,j,s) triplets.
5. Minor changes to simple_bundle_adjuster to enable logging at startup.
