why are you redefining this constant here?

I moved the definition here and made it private, so that it would be exposed only through the relevant BlockLimitsFn.

We could keep this in a side branch, but could still consider putting the hooks into |

Motivation
Towards #3002
New Code
This program can be used to "analyze the mempool". This can be used to compute statistics, especially:
More specifically, this tool can be used to mine an "unlimited block". That is, it will attempt to build a block from the transactions in the mempool, but will never run out of space in the block.
Each transaction in the mempool will be tried once.
Changed Code
To support this change, we introduce
BlockLimitsFunctions, which allows the user to specify custom block limits. Currently, there is no choice but to take the limits from theStacksEpoch. Now, users writing custom tools or tests will be able to override these values.Testing
The new memory analyzer tool is just tested by running it. It's not currently in production.
The changes to introduce
BlockLimitsFunctionsare tested by the existing tests.
