hs_pow: bump client-side effort limit from 500 to 10000
500 was quite low, but this limit was helpful when the suggested-effort
estimation algorithm was likely to give us large abrupt increases. Now
that this should be fixed, let's allow spending a bit more time on the
client puzzles if it's actually necessary.
Solving a puzzle with effort=10000 usually completes within a minute
on my old x86_64 machine. We may want to fine tune this further, and it
should probably be made into a config option.
