Revert "Fix T71126: add old hotkeys to set start/end frame in the timeline to"

This caused T71483.
Having timeline and dopesheet merged in 2.8 makes using S/E keys in timeline not work well.
2.7x keymap needs to fit with 2.8x internals, so probably 2.7x keymap will have to live with Ctrl+Home / Ctrl+End here.

This reverts commit 4fbcbbfb967cb0fdff11dfc1646a1c55bca96f1d.

Fluid Particles: fix threading crash with viscoelastic springs.

As correctly pointed out by a comment in the code, adding
new springs wasn't thread safe, and caused crashes.

Fix by buffering new springs in intermediate thread-local
arrays, which are flushed on the main thread. This is valid
because the new springs are not used until the next sim step.
