Currently, the logic for exporting symbols is rather complicated: when
tests are enabled internal symbols are exported in addition to the
public symbols. Such logic causes several problems. (1) Test binaries
link against a Ceres build that is different from the final release
since fewer optimizations are applied if more symbols are exported. (2)
Also, some toolchains hide symbols by default breaking the existing
logic eventually causing linker errors.
Since internal symbols are not intended to be used outside of the
project, we can compile them into object files and use exactly the same
binary code both for the final build and the tests without relying on
conditionals.
By default, all symbols are now hidden unless annotated as public.
Internal symbols are explicitly marked as not being exported in case
users chose not to hide symbols by default.

Add a class that given a block sparse matrix m will compute
the product m'*m efficiently.
This code is refactoring and cleanup of the code in
CompressedRowSparseMatrix devoted to computing the inner product.
In that class, the code is mistakenly said to be computing
the outer product. It is also devoted to computing the inner
product of a CompressedRowSparseMatrix with itself.
This code works with BlockSparseMatrix objects instead, which
are simpler to deal with as they are better structured to handle
block sparse matrices.
