Re-launch floonet (#2249)
*  Fix secondary scaling bugs;  rename is_testnet -> is_floonet (#2215)
* add global::is_mainnet()
* use it to change pre-genesis pow type
* rename is_testnet -> is_floonet
* Support multiple chain configurations (#2217)
* Support multiple chain configurations
Supports generating the proper configuration for each chain type
(mainnet, floonet, usernet). Will run them by default under
their respective root directory (~/.grin/main, ~/.grin/floo, etc).
Assigned default ports for mainnet, overriding them to keep Floonet
ports unchanged.
For now, starting on mainnet will abort.
* Fixed usernet command line help message. Fixes #2217
* Differing magic numbers for each chain type (#2208)
* stick to e=H(R|P|m) when use schnorr signature (#2200)

85433c659d Introduce a constant for peer send channel capacity (#1761)
We implicitly use it also in body_sync, so it's hard to keep it in sync.

Use round robin for peer selection in body sync
We select a peer to ask a block randomly. Peer's send channel has
capacity 10. If we need too many blocks we limit number of blocks to asks as a number of peers
* 10, which means that there is some probability (pretty high) that we
will overflow send buffer capacity.
This fix freezes a peer list (which gives also some performance boost)
and create a cycle iteraror to equally distribute requests among the
peers.
There is a risk that a peer may be disconnected while we are sending a
request to the chanel, but stricltly speaking it was possible in the old
code too, perhaps with a lower probability.
Fixes #1748
