Sameer Agarwal caf614a6c1 Modernize code using c++17 constructs 
Mostly done using

cmake-build -checks='-*,google-*,modernize-*,-modernize-use-nodiscard,-modernize-use-trailing-return-type' {} -fix \;

Sergiu Deitsch c8658c8992 Modernize more 
Apply clang-tidy Google and modernize fixes without trailing return type
using:

$ clang-tidy -p <build-dir> \
  -checks='-*,google-*,modernize-*,-modernize-use-trailing-return-type' {} -fix

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.

Sameer Agarwal fc9336e12a Deprecate mutex.h 
Use C++11's std::mutex and std::lock_guard instead.

Sameer Agarwal 2145c10539 Improve ExecutionSummary 
1. Replace two maps by 1.
2. Update number of calls and the time for the call at the cost
   of a single map lookup.
3. Add Solver::Summary::num_linear_solves.

Fixes https://github.com/ceres-solver/ceres-solver/issues/340

Sameer Agarwal 0251359830 A bunch of minor changes. 
1. Fix a typo in auto_diff_cost_function.h
2. Fix and update Solver::Summary::FullReport() text labels.
3. Add logging of the number of residual and jacobian evaluations
   to the full report. The GradientProblemSolver already does this.

Keir Mierle 7492b0d8de Update copyright headers with new year and URL 
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.

Sameer Agarwal bcc865f81c Remove using namespace std; 
For historical reasons we had a "using namespace std;" in port.h. This
is generally a bad idea. So removing it and along the way doing a bunch
of cpplint cleanup.

Sameer Agarwal 509f68cfe3 Problem::Evaluate implementation. 
1. Add Problem::Evaluate and tests.
2. Remove Solver::Summary::initial/final_*
3. Remove Solver::Options::return_* members.
4. Various cpplint cleanups.

Sameer Agarwal 42a84b87fa Expand reporting of timing information. 
1. Add an ExecutionSummary object to record execution
   information about Ceres objects.
2. Add an EventLogger object to log events in a function call.
3. Add a ScopedExecutionTimer object to log times in ExecutionSummary.
4. Instrument ProgramEvaluator and all the linear solvers
   to report their timing statistics.
5. Connect the timing statistics to Summary::FullReport.
6. Add high precision timer on unix systems using
   gettimeofday() call.
7. Various minor clean ups all around.

Sameer Agarwal bdd87c03ed Add an ExecutionSummary object that the Evaluator and LinearSolver can use to 
report execution statistics of all kinds.

Currently a single map which maps arbitrary strings to doubles is supported,
which allows for precise timing information to be communicated.
