Remove logic invoked based on obsolete variable definitions. Use new
(explicit) target_link_libraries syntax to link binaries against
dependencies. Do not rely on prior knowledge about the compiler for
specifying flags and system libraries but instead directly test their
presence to be more robust.

- Change formatting standard to Cpp11. Main difference is not having
the space between two closing >> for nested templates. We don't
choose c++14, because older versions of clang-format (version 9
and earlier) don't know this value yet, and it doesn't make a
difference in the formatting.
- Apply clang-format to all (non generated) internal source files.
- Manually fix some code sections (clang-format on/off) and c-strings
- Exclude some embedded external files with very different formatting
(gtest/gmock)
- Add script to format all source files

This is mostly just applying the existing clang format config, except:
- Use NOLINT on overlong comment lines.
- Wrap some sections in 'clang-format off' / 'clang format on'.
- Manually split or join some multi-line strings.

- As our minimum required version of gflags (2.2) exports itself as
a CMake package and this is the case for the default 18.04 package
we can use the gflags target directly.
- Replaces forced use of CONFIG in find_package(gflags) with a check
that the gflags imported target exists to avoid ambiguity with
libgflags if installed in a default location. This permits users to
override the gflags detection should they so choose, provided that
they do so via an imported target.
- Also removes some previously removed legacy GLAGS_ vars from the
installation docs.

- This reflects modern CMake style, and also provides a measure of
protection against missing find_package() imports in downstream
clients resulting in linker errors when 'ceres' matches the compiled
library and not the imported target.
- The original 'ceres' target remains, as a local imported interface
target created by CeresConfig for backwards compatibility.

This commit includes the following:
- Changes to CMake to make it safer to see which compiler flags are supported,
so this way we do not need to worry about version checks in CMake.
- Unix platforms (which includes both Linux and Apple as far as i can tell)
will now enable -Wmissing-declarations warning for the whole Ceres.
- Changes in all sources to solve missing declaration warning. In most cases
it was either matter of using static qualifier or moving functions to an
anonymous namespace.
In one case the function got removed, since it seems to be unused.
Additionally, in slam examples there was a non-inlined function implementation
in a header, which is a direct way to cause linking errors if other .cc file
will include that helper header.
- All third party sources (which is currently only gmock) has this extra
paranoid warning disabled.
This warning is important in the following cases:
- Detect helper functions which are not needed anymore.
- Avoid unnoticed pollution of namespace.
- Avoid bad level calls.
- Avoid missing updates in header files after changes in implementation file.
- Helps integrating Ceres into software where paranoid warnings are important.
