We now have our halving schedule implemented until the BR goes to zero.
The data was calculated via two new scripts which are in ./contrib :

These show that the block subsidy for miners goes to 0 at the 31st halving
and that the Founders Reward AKA Dev Tax goes to 0 at the 27th halving. There
is also some current KMD internals code that we inherited that prevents
the FR from being less than 10000, so that code would currently set our FR
to 0 at the 14th halving and lead less HUSH being mined than the planned 21M and
even a bit less than the amount under 21M that normally happens, such as in BTC.
We have some time to deal with the bug, since halving 14 is in about 52 years.
These new CLI args control the interval of the 1st halving (between
1st and 2nd halving blocks) and the 2nd halving (between 2nd and 3rd
halving blocks). -ac_halving2 is used for all subsequent halvings.
This allows devs to simulate things via the CLI without changing code,
to verify things work as expected at halvings in the far future.
This extremely important consensus-changing code takes into account
that with our new 75s block time, which gives us twice as many blocks
per day, we must divide our block reward by two in the next
halving interval, becoming 3.125 HUSH per block insted of 6.25 HUSH
under the old rules of 150s blocks.
Subsequent halving intervals do not change block times, and so they
follow the normal pattern of halving.
This commit has a number of rough edges:
* Final BR height is still incorrect
* Due to above, exact number of halvings is unknown under new
75s blocktime
