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  
lookuplocal - looks for LeaseSet with specified address in router's netdb
