remove github capabilities workaround from got-send-pack, it is not needed This workaround was inherited from git9, which claims that Github did not send capabilities. Protocol traces show that Github's server does in fact advertise its capabilities. Git protocol capabilities are hidden behind a NUL byte in the middle of the first refline sent by the server. This makes them easy to miss when treating a refline as a C string. I guess this is why Ori concluded that Github didn't send any capabilities. Or perhaps Github has been fixed since.

add 'got send' command for sending changes to remote repositories Known to work against git-daemon and github Git server implementations. Tests by abieber, naddy, jrick, and myself. Man page additions reviewed by Lucas.
