removed nested synchronization (which had been causing undetected deadlocks)
made sync blocks smaller, though this may have opened holes related to
resent ACK/SYN/CLOSE packets that are delivered in a race. I'm not as
fluent in the ministreaming lib code as i should be (yet), but duck's thread
dumps were showing hundreds of threads waiting on a lock that'll never get
released (since the only way to release it would be to receive another
packet, and no more packets can be received until the lock is released, etc)
also, I2PSession is threadsafe - i can see no reason to synchronize on it
(and it was being synchronized on only part of the time?)
also, refactored the charset encoding stuff and minor log tweaking
i've been testing this for the last hour or so, on eepsites and squid (large
and small files), as well as irc, and there haven't been any glitches. but
it needs more testing before it can be released, obviously.
better error reporting;
* Added an I2PSocketManager.destroySocketManager() method, that closes all
the managed sockets and destroys the associated I2PSession.

won't be accepted until the server app actually requires an I2PServerSocket
from the I2PSocketManager.
It allows both to add a little bit of functionality, and to fix a nasty bug: it
was possible to hang an app that connects through the I2PSocketManager but
actually doesn't accept() connections (if 2 connection requests were sent
to the app, the I2PSocketManager got stuck waiting forever on
I2PServerSocketImpl.getNewSocket()).
