Rather than a `L` (linked), `O` (overridden) or `M` (missing) prefix for the
name, show the existing library status icons. See D7999 for screenshots.
Note that when using preview icons, or if the search menu contains items with
own icons (e.g. brush icons), we still fallback to the prefix solution.
Zero or fake user is still indicated with a prefix.

Now that we have a uniform consistent behavior in all our ID duplicate
funtions, we can easily factorize it greatly. Code gets cleaner,
smaller, and less error-prone.
Note that ultimately, this duplicate/deep copy behavior could be added
as a callback of IDTypeInfo.
We could also rethink the duplicate flags (some data, even some obdata,
like Lattice, are not coverred currently).
And so on. But at least code should now be much more easily maintainable
and extendable.
This is actually a nice issue due to too much optimization...
* Making an ID local just reuse the linked one whenever possible, instead of
actually making a copy of it.
* Therefore, the collection containing that ID is seen as unchanged, since
the pointer itself remained the same.
* But on undo step, there is no way to reuse that local object, which then
gets deleted, and linked one gets re-created - at a different address.
* Collection, however, since unchanged, is not updated at all and thus keeps
reference to the to-be-deleted local object, instead of the linked one.
* Issue gets even worse with viewlayers, this leads to the crash.
To address this, this patch adds a 'virtual' update flags that does nothing
in update case, but will ensure that the affected IDs using the one made local
are properly detected as changed across the relevant undo step.
Note that the recalc flags were chosen mostly for a logical reason, and also
because they are already properly dealt with and cleared by undo code,
so this looks like the optimal solution.

This commit enables basic copy of overrides on generic ID level, as well
as from (deep) copy operators for objects and collections.
So e.g. if your linked overridden caracter is in a collection, you can
now (from the outliner) Duplicate that override collection to get a new
overriding copy of the character.
We still need operators (new or modifying existing ones) to handle that
from 3DView e.g.
Note that deep copy code for objects/collections (and incidently
animdata) had to be modified to avoid duplicating/making local IDs that
remain linked ones being used by overrides ones.
Thing is, user code should not have the responsibility to check that
libquery is valid. Such checks are only source of confusion and errors
as nobody will think about finding and updating them in some obscure
specific area of the code...
Code dealing with embedded data was pre-existing proper generic
handling of those by `BKE_library_foreach_ID_link()` - and was never
updated for scene's master collection it would seem...
Note that such fix/refactor is a bit risky at this point in the release
cycle, but on the other end previous situation was really broken. So
finger crossed. :|

This removes grease pencil brush creation/dat-block delete on load,
since this causes duplicate data-blocks.
Add assert to prevent this happening in the future
since the error is isn't obvious.
Remove resetting of ID uuid session counter, it is not really needed
anymore, and not trivial to do this properly everytime.
Thanks @brecht for investigating this.
We need to re-generate a new session uuid for the UI-related data-blocks
that are kept across file reading, when load UI is disabled. Otherwise
there will be several IDs with same uuid, which is an ensured way to
crash in new undo code.
Logic to handle shepkeys datablocks in helper in 'make local' code that
checks which ID should be copied, and which can be directly made local,
was wrong.
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

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.
Mpving utils from idcode to idtype proved to be somewhat painful for
some reasons, but now all looks good.
Had to add a fake/empty shell for the special snowflake too,
`ID_LINK_PLACEHOLDER/INDEX_ID_NULL`...
Embedded data should always be considered as outside of Main database
here.
Note that it's a bit of an edge case to decide whether those should
always have their `LIB_TAG_NOMAIN` set too, or not? For now, let's keep
things as they are here.
'Private' can be a rather confusing term, especially when considering
its meaning in programming languages.
So now root node trees and master collections are 'embedded' IDs
instead.
Only covers direct usages of new callbacks from IDTypeInfo.
We still have a lot of those switch/case, many can probably go away
with minimal refactor now, but that will be for later.
This was particularly strange because we had a _free_data() function.
But still the one I replaced was of course the _free() one.
And we should rename the _free_data_ function later to avoid confusions.
