Surrounding includes with an 'extern "C"' block is not necessary anymore.
Also that made it harder to add any C++ code to some headers, or include headers
that have "optional" C++ code like `MEM_guardedalloc.h`.
I tested compilation on linux and windows (and got help from @LazyDodo).
If this still breaks compilation due to some linker error, the header containing
the symbol in question is probably missing an 'extern "C"' block.

Particle systems have two names: the name of the particle system itself,
and the name of the particle system settings. The USD exporter used to
use the latter name, and now switched to the former. This is to be in
line with the Alembic exporter, as well as to give users more freedom in
the naming (the particle system can have a unique name but still share
settings from other particle systems).
The construction of the export graph is now split into a few steps:
- Construct a `HierarchyContext` object for the to-be-exported object.
- Determine the graph index, i.e. the export-parent and the duplicator.
- Update the `HierarchyContext` object for this graph index.
This allows the upcoming new Alembic exporter to override the location of
an object in the export graph, in order to support "flattened" exports.
Aside from that, this also simply makes the code cleaner.
No functional changes.
There was a bug in the `connect_loose_objects()` function, which caused
some objects to be exported twice (once for real, and once
transform-only). This is now resolved.
The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.
All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).
No functional changes.
The files are now split up into the following sections:
- `BKE_anim_path.h` and `anim_path.c` for path/curve functions.
- `BKE_anim_visualization.h` and `anim_visualizationanim_path.c` for
animation visualization (mostly motion paths).
- `BKE_duplilist.h` for DupliList function declarations. These were
already implemented in `object_dupli.c`, so they were rather out of
place being declared in `BKE_anim.h` in the first place.
No functional changes.
The `check_is_animated()` function will be used by the upcoming Alembic
exporter as well. There is nothing USD-specific in the function.
No functional changes.
printf is called for a size_t (64 bit on x64) type
but the formatter is `%lu` (32 bit) leading to a
warning with MSVC.
`%zu` is the appropriate formatter.
This moves the `alembic`, `avi`, `collada`, and `usd` modules into a common
`io` directory.
This also cleans up some `#include "../../{somedir}/{somefile}.h"` by
adding `../../io/{somedir}` to `CMakeLists.txt` and then just using
`#include "{somefile}.h"`.
No functional changes.
