Move files from src/ to src/nvim/.
- src/nvim/ becomes the new root dir for nvim executable sources.
- src/libnvim/ is planned to become root dir of the neovim library.

RStream will be the main way Neovim receives asynchronous messages, so it is
best to have a specialized EventType for it. A new flag parameter was added to
`rstream_new` which tells the RStream instance to defer event handling for later
with KE_EVENT instead of handling it directly from libuv callback.

Possible bug reported by @oni-link [here](https://github.com/neovim/neovim/pull/485/files#r11664573).
It was handled by doing a circular walk through a key buffer and saving the
index between calls with a static variable.
Also replaced some `char_u` occurrences by `uint8_t` and removed unused
headers in input.c module.

As of v0.11.23 libuv's uv_timer_cb, uv_async_cb, uv_prepare_cb, uv_check_cb and
uv_idle_cb no longer require a status parameter (this went unused in the first
place).
Bump third-party dependency `libuv` up to 0.11.23 and remove the extra
parameters from the callbacks.

K_EVENT/KE_EVENT are used to signal any loop that reads user input(scattered
across normal.c edit.c , ex_getln.c and message.c) of asynchronous events that
were not initiated by the user.
Representing non-user asynchronous events as special keys has the following
advantages:
- We reuse the normal vim redrawing code. As far as the rest of the code in
edit.c/normal.c is concerned, it's just the user pressing another key.
- Assume less about vim tolerance for "out-of-band" modifications to its
internal state.
- We still have a very complex codebase and it's hard to predict what bugs may
be introduced by these changes. With this we implement asynchronicity in a way
that will be more "natural" to the editor and has less chance of causing
unpredictable behavior.
As the code is refactored, we will be able to treat user input as an 'event
type' and not the other way around(With this we are treating arbitrary events as
a special case of user input).

This removes all signal handling code from os_unix.c to os/signal.c. Now signal
handling is done like this:
- Watchers for signals are registered with libuv default event loop
- `event_poll` continuously calls `poll_uv_loop` to produce events until it
receives user input, SIGINT or a timeout
- Any signals received in `poll_uv_loop` will push events to a queue that is
drained and processed by `event_poll`
Signals aren't handled directly in the libuv callback to avoid recursion in the
event loop(which isn't supported by libuv).
The same principle will apply to other events in the future: Push to a queue
from a libuv callback and drain it from `event_poll`

* Add const.
* Fix conditions (move && from end to start of line).
* Use int32_t instead of long.
* Use //-style comments.

This enum doesn't need to be public since `event_poll` is only interested in
user input(but other events may be handled by libuv callbacks).

The functions `mch_inchar`, `mch_breakcheck`, `mch_char_avail` were
reimplemented on top of libuv. Here's how it works:
- When Neovim needs to wait for characters, it will transfer control to libuv
event loop.
- When the libuv event loop gets user input, it will transfer control back to
Neovim
- Neovim uses the `input_read` function to get the actual data read by libuv.
With this scheme its possible to keep Neovim single-threaded while enjoying the
benefits provided by libuv.
This commit leaves SIGWINCH broken for now
