To keep running these tests relatively fast and practical to run often,
running it on all .blend files is a bit much. So now we only run it on
files from this directory.
Additionally this adds supports for following symlinks, so that you can
easily symlinks to other directories if you want to tests extra files
which may have linked libraries.
The new data structure uses open addressing instead of chaining to resolve collisions in the hash table.
This new structure was never slower than the old implementation in my tests. Code that first inserts all edges and then iterates through all edges (e.g. to remove duplicates) benefits the most, because the `EdgeHashIterator` becomes a simple for loop over a continuous array.

- Was setting active state, making it necessary to backup/restore
active object in cases where this isn't needed.
Existing scripts are explicitly setting the active object when needed.
- Use a boolean select arg (toggle selection wasn't used anywhere).
- Add an optional view layer argument since scripts should be able to
operate outside the user context.
We already had a BKE_main.h header, no reason not to put there
Main-specific functions, BKE_library has already more than enough to
handle with IDs and library management!
Simple find_nearest relies on a heuristic for efficient culling of
the BVH tree, which involves a fast callback that always updates the
result, and the caller reusing the result of the previous find_nearest
to prime the process for the next vertex.
If the callback is slow and/or applies significant restrictions on
what kind of nodes can qualify for the result, the heuristic can't
work. Thus for such tasks it is necessary to order and prune nodes
before the callback at BVH tree level using a priority queue.
Since, according to code history, for simple find_nearest the
heuristic approach is faster, this mode has to be an option.
This reverts reverting commit rB55324b8a2e6799300, and do proper 'cleanup' (sigh)
in gtest as well.
Sorry for the noise, did not understood what had happened here
immediately. :/
If the user only needs insertion and removal from top, there is
no need to allocate and manage separate HeapNode objects: the
data can be stored directly in the main tree array.
This measured a 24% FPS increase on a ~50% heap-heavy workload.

Currently some modes share tool keymaps, we might want to disable
this since it's confusing editing one thing in multiple places.
However this should be resolved in the tool definitions.
Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT
Simple isn't a good prefix for library names since
lots of unrelated modules could be called 'simple'.
Include 'py' in module name since this is a subset of Python,
one of the main motivations for this is to be Python like/compatible.
Recently @sergey found that hard-coding evaluation of certain very
common driver expressions without calling the Python interpreter
produces a 30-40% performance improvement. Since hard-coding is
obviously not suitable for production, I implemented a proper
parser and interpreter for simple arithmetic expressions in C.
The evaluator supports +, -, *, /, (), ==, !=, <, <=, >, >=,
and, or, not, ternary if; driver variables, frame, pi, True, False,
and a subset of standard math functions that seem most useful.
Booleans are represented as numbers, since within the supported
operation set it seems to be impossible to distinguish True/False
from 1.0/0.0. Boolean operations properly implement lazy evaluation
with jumps, and comparisons support chaining like 'a < b < c...'.
Expressions are parsed into a very simple stack machine program
that can then be safely evaluated in multiple threads.
