MsgPack-RPC dispatch based on function array lookup #864

alternative dispatching methods (e.g. string method id dispatch).
cmake: upgrade libuv 0.11.23 -> 0.11.26 #911

reduces its prominence in performance traces. This allows us to better see
what's really causing slowness.

Add vim_feedkeys API function

- New API function to push data to the typeahead buffer - this should
  equivalent to the vimscript feedkeys() function
- In Vim there was a --remote-send command to insert input into a
  Vim server instance. Besides accepting key sequences it also
  translated special keys such as <CR> or <Leader>, backslash notation
  is ignored. This commit backports the original Vim handler for
  --remote-send as a bool option for vim_feedkeys()
