add SFTPFile.check and server support (and test) -- it's an sftp extension that allows a client to retrieve the hash of part or all of a file without downloading it. we're probably the only ones who implement it yet
try to handle utf8 paths in a sane way in SFTPClient: assume incoming strings are already utf8, and encode incoming unicodes -- for return values, use str if an ascii encoding will work, otherwise return a unicode
split out Packetizer, fix banner detection bug, new unit test
split out a chunk of BaseTransport into a Packetizer class, which handles
the in/out packet data, ciphers, etc. it didn't make the code any smaller
(transport.py is still close to 1500 lines, which is awful) but it did split
out a coherent chunk of functionality into a discrete unit.
in the process, fixed a bug that alain spineux pointed out: the banner
check was too forgiving and would block forever waiting for an SSH banner.
now it waits 5 seconds for the first line, and 2 seconds for each subsequent
line, before giving up.
added a unit test to test keepalive, since i wasn't sure that was still
working after pulling out Packetizer.
integrated laptop work (test commit)

rewrite channel pipes to work on windows
the pipe system i was using for simulating an os-level FD (for select) was
retarded. i realized this week that i could just use a single byte in the
pipe to signal "data is ready" and not try to feed all incoming data thru
the pipe -- and then i don't have to try to make the pipe non-blocking (which
should make it work on windows). a lot of duplicate code got removed and now
it's all going thru the same code-path on read.
there's still a slight penalty on incoming feeds and calling 'recv' when a
pipe has been opened (by calling 'fileno'), but it's tiny.
removed a bunch of documentation and comments about things not working on
windows, since i think they probably do now.
add methods for sending/receiving a channel's exit status
track a channel's exit status and provide a method (recv_exit_status) to
block waiting for it to arrive. also provide a convenience method for
servers to send it (send_exit_status). add shutdown_read and shutdown_write.
fix a bug in sending window change requests.
sftp server support!
finally check in sftp_handle (file handle abstraction), sftp_si (server
interface), and sftp_server (server implementation) -- all of which make
a roughly 90% implementation of server-side sftp.
don't forget demo_windows.py
update MANIFEST.in to include demo_windows.py and not include the demo
keys (they're in tests/ now). clean up the README to explain the demo
scripts better now, since there are so many of them. then fix up the
demo scripts to look in tests/ for the keys.
demo_windows.py doesn't need to call get_pty() (in fact, i think that's
blowing openssh's mind) and was executing the wrong command.
note pycrypto 2.0 in README
update the README to note that pycrypto 2.0 works (i just tried it). also
fix the name from pyCrypt back to pycrypto -- that project is having trouble
making up its mind about naming. :)
