BLI_task: Initial implementation of pooled threaded index range iterator. This code allows to push a set of different operations all based on iterations over a range of indices, and then process them all at once over multiple threads. This is mainly interesting for relatively low amount of individual tasks, as expected. E.g. performance tests on a 32 threads machine, for a set of 10 different tasks, shows following improvements when using pooled version instead of ten sequential calls to `BLI_task_parallel_range()`: | Num Items | Sequential | Pooled | Speed-up | | --------- | ---------- | ------- | -------- | | 10K | 365 us | 138 us | 2.5 x | | 100K | 877 us | 530 us | 1.66 x | | 1000K | 5521 us | 4625 us | 1.25 x | Differential Revision: https://developer.blender.org/D6189 |
