Sergiu Deitsch f90833f5fa Simplify symbol export
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.

# Script for explicitly generating template specialization of the
# SchurEliminator class. It is a rather large class
# and the number of explicit instantiations is also large. Explicitly
# generating these instantiations in separate .cc files breaks the
# compilation into separate compilation unit rather than one large cc
# file which takes 2+GB of RAM to compile.
#
# This script creates two sets of files.
#
# 1. schur_eliminator_x_x_x.cc
# where, the x indicates the template parameters and
#
# 2. schur_eliminator.cc
#
# that contains a factory function for instantiating these classes
# based on runtime parameters.
#
# The list of tuples, specializations indicates the set of
# specializations that is generated.
# Set of template specializations to generate
