Compute one octant of the Ewald corrections at start-up for future use when running with the gravity checks.

runner_dopair_grav() should abort if the distance between the cells is larger than the mesh smoothing scale.

Updated version number to 0.6.0 to reflect the large number of changes to the threadpool, drifts, MPI and scaling performance in the last few months.

Periodic gravity speed and accuracy improvements

Threadpoolize all the things

These are all the remaining function from the list in #338. I've tested this as far as possible on my laptop, i.e. MPI and gravity *should* work.

Merge branch 'threadpoolize_all_the_things' of gitlab.cosma.dur.ac.uk:swift/swiftsim into threadpoolize_all_the_things

convert engine_make_self_gravity_tasks to use a threadpool_map. still have to create the grav_ghost tasks sequentially, but i think that's ok since there are 128 times fewer of them.

Engine barrier

Following the results in the `threadpool_task_plots` branch, I've replaced the elaborate hand-crafted `engine_barrier` function by two `pthread_barrier`s.

As a result, the runner threads should all start, and synchronize, faster.

engine_launch is only ever called with all threads, remove the option to limit the number of running threads.

Added the EAGLE_6 test case. This is a very small cosmological volume not representative of the workload of large runs.

Allocate a separate sort array for each dimensions.

As discussed, fixes #334.

add a parameter for space_subsize_self_grav, gravity self-interactions on cells with more than this number of particles will be split up.

Tiny bug fix in engine_marktask()

In engine_marktask() only check whether to rebuild the space for density pair/sub-pair, not for all sub-types of pair/sub-pair. Leads to problems with mixed gravity/hydro runs otherwise.

Fix problems with empty hydro tasks.

Fixes #333.

Fixes to the threadpool

Don't free the `tp->threads` struct when not allocated (1 thread).
Also set the function when logging one thread (otherwise we don't 
get the function names in log).

More testing to check 1 thread behaviour and different numbers of
threads. Tweak output to make progress more obvious.
