* Missing include for `dlib::loss_multiclass_log_per_pixel_::label_to_ignore`
I was trying to compile the examples and encountered this issue after moving `rgb_label_image_to_index_label_image` to cpp file. Headers should include all symbols they mention.
* Update pascal_voc_2012.h
Should use the official entrypoint for including dnn stuff.

* wip: layer normalization on cpu
* wip: add cuda implementation, nor working yet
* wip: try to fix cuda implementation
* swap grid_strid_range and grid_strid_range_y: does not work yet
* fix CUDA implementation
* implement cuda gradient
* add documentation, move layer_norm, update bn_visitor
* add tests
* use stddev instead of variance in test (they are both 1, anyway)
* add test for means and invstds on CPU and CUDA
* rename visitor to disable_duplicative_bias
* handle more cases in the visitor_disable_input_bias
* Add tests for visitor_disable_input_bias
Now the user doesn't have to supply a visitor capable of visiting all
layers, but instead just the ones they are interested in. Also added
visit_computational_layers() and visit_computational_layers_range()
since those capture a very common use case more concisely than
visit_layers(). That is, users generally want to mess with the
computational layers specifically as those are the stateful layers.
* add visitor to remove bias from bn_ inputs (#closes 2155)
* remove unused parameter and make documentation more clear
* remove bias from bn_ layers too and use better name
* let the batch norm keep their bias, use even better name
* be more consistent with impl naming

* Simplify the segmentation network structure; make the object detection network more complex in turn
* Problem: CUDA errors not reported properly to console
Solution: stop and join data loader threads even in case of exceptions
* Minor parameters tweaking
* Loss may have increased, even if prob_loss_increasing_thresh > prob_loss_increasing_thresh_max_value
* Add previous_loss_values_dump_amount to previous_loss_values.size() when deciding if loss has been increasing
* Improve behaviour when loss actually increased after disk sync

* Minor type changes
the code, but it helps visual studio use less RAM when building the example,
and might make appveyor not crash. It's also a
slightly cleaner way to write the code anyway.
* Exposed jitter_image in Python and added an example
* Return Numpy array directly
* Require numpy during setup
* Added install of Numpy before builds
* Changed pip install for user only due to security issues.
* Removed malloc
* Made presence of Numpy during compile optional.
* Conflict
* Refactored get_face_chip/get_face_chips to use Numpy as well.
* Add example of semantic segmentation using the PASCAL VOC2012 dataset
* Add note about Debug Information Format when using MSVC
* Make the upsampling layers residual as well

* Remove the probably-now-unnecessary set_dnn_prefer_smallest_algorithms call
* Review fix: remove the batch normalization layer from right before the loss
* Review fix: point out that only the Visual C++ compiler has problems.
Also expand the instructions how to run MSBuild.exe to circumvent the problems.

* Review fix: use dlib::join_rows. Also add some comments, and instructions where to download the pre-trained net from.
* Review fix: make formatting comply with dlib style conventions.
* Review fix: output training parameters.
* Review fix: remove #ifndef __INTELLISENSE__
