no remove double property lookups in ED_fileselect_set_params and redundant NULL check in file_main_area_draw.

another header edit needed

blenderplayer builds again

minor changes to edgehassh/ghash
- no need to zero vars when freeing ghash
- de duplicate ghash remove code.
- edgehash clear now works more like ghash.

replace hashes with sets where possible.

BKI_gset and EdgeSet api, use when hash values aren't used (reuses ghash internally without allocating space for the value).

Fix [#36289] Not change children object on freez layer when change frame.

When hiding the layer of an object, switching to a different fram, and showing again that layer, things like object's parenting were not handled... Just set do_time option of DAG_on_visible_update() to True when updating layers.

Note: maybe we could re-enable layers animation... not sure though ;)

Partial revert of UI appearance changes in r52778 in the Strokes tab of the Freestyle Line Style panel.

move doxy docs out of the ghash header into the C file.

clearing the mempool can now keep more then a single element reserved.

fix leak in BLI_ghash_clear(). was never freeing entries, add BLI_mempool_clear utility function.

code cleanup for mempool, refactor chunk initialization into a static function.

merge mempool allocs per chunk, include the data in the BLI_mempool_chunk alloc.

doxygen docs for ghash/edgehash

For pointer hashing use the same method as python, it gives better distribution.

some tests with high poly mesh data in hashes.
- empty buckets before 4-5%, after 1-2%
- speedup for hash lookups, in my tests lookups take approx ~60% of the time they did before.

use ints for ghash/edgehash flags, since its allocated theres not much point to try save a few bytes here.

Quiet annoying VC++ warning C4819: The file contains a character that cannot be represented in the current code page.

ghash: reserve size when its known or can be guessed close enough.
also avoid allocs per node in pbvh_bmesh_node_limit_ensure()

Fix bad draw of plane track when using Tiny display option

Add stdlib.h to solve compilation error caused by missing abort() prototype

Perhaps we'd better move this include to BLI_utildefines as we made with
with other includes needed for BLI_abort?
