i2pd-specific changes to I2P protocols
======================================

# SAM
SESSION CREATE and DEST GENERATE support additional parameter `CRYPTO_TYPE` specifying crypto type for new local destination  

new values for `SIGNATURE_TYPE`:
- `GOST_GOSTR3411256_GOSTR3410CRYPTOPROA` or `9`
- `GOST_GOSTR3411512_GOSTR3410TC26A512` or `10`

# I2PControl
`i2p.router.status` is 1 if shared local destination is ready, and 0 if not  
`i2p.router.net.tunnels.successrate` returns tunnel creation success rate in percents  
`i2p.router.net.total.received.bytes` returns total received bytes since last restart  
`i2p.router.net.total.sent.bytes` returns total sent bytes since last restart  
# BOB
Unlike Java-I2P, i2pd keep supporting BOB with the following extensions:
- newkeys
- signaturetype
- cryptotype.

DSA and ElGamal by default.
