Cumulative updates(MIPS softfloat support)

1. added AES based nonce generator, faster than MD5 in all scenarios.
2. set 'GOMIPS=softfloat' as the default option in compiling for MIPS platform.
3. add a hint for key derivation for slow CPUs.
4. compiler updated to go1.11.

Improvements on connection speed

A severe bug introduced by xtaci/kcp-go#65 prevents the server-side of kcptun from processing the incoming FEC packet now discovered(which leads to unnecessary retransmissions). This release has fixed that bug(by disposing the that feature), and the benchmark showed MUCH FASTER than previous versions.

EVERYONE is suggested to upgrade to this version, meanwhile, all functional PR will be rejected releated to kcp-go to prevent such mistakes.

Repack executable for last version

1.Repack version v20171129, due to the profiling option in testing(port 6060), the binary size of client side(ONLY) is larger than the previous versions, this repacking fixed this issue, with no functional changes.
