- Add input_teardown/signal_teardown to take care of closing signal/stdin
handles.
- Call those functions in event_teardown, and ensure there are no active handles
by entering an infinite loop when there are unclosed handles(think of this as
an assertion that can't go unoticed on travis).
- Move event_teardown call to the end of mch_exit. That is required because
event_poll may still be called in that function.
Commit @264e0d872c("Remove automatic event deferral") removed the immediate
event queue because event deferral now had to be explicit. The problem is that
while some events don't need to be deferred, they still can result in recursive
`event_poll` calls, and recursion is not supported by libuv. Examples of those
are msgpack-rpc requests while a server->client request is pending, or signals
which can call `mch_exit`(and that will result in `uv_run` calls).
To fix the problem, this reintroduces the immediate event queue for events that
can potentially result in event loop recursion. The non-deferred events are
still processed in `event_poll`, but only after `uv_run` returns.
If the server fails to start(due to used address for example), the
`server_start` function was freeing the handle memory before it was properly
removed from libuv event loop queue. Fix that by replacing the `free(server)`
call by `uv_close` call, which will take care of freeing the server on the next
event loop iteration. Also replace `EMSG` calls by `ELOG`/`WLOG`.
- Rename WriteData to WRequest
- Inline uv_write_t into WRequest, avoiding an extra allocation
- Manage WBuffer/WRequest instances using klib memory pools
Use a timer to periodically compare the current HR time against the HR time of
when `job_stop` was called. After 1 second, send SIGTERM, after 2 seconds, send
SIGKILL. The timer is only active when there's at least one `job_stop` call
pending.
Passing NULL as the callback for stdout/stderr will result in job_start ignoring
stdout/stderr, respectively. A 'writable' boolean argument was also added, and
when false `job_start` will ignore stdin.
Also, refactor os_system to allow passing NULL as the `output` argument.
Commit @709685b4612f4 removed the close_job_* calls when uv_spawn fails because
of memory errors when trying to cleanup unitialized {R,W}Stream instances, but
the uv_pipe_t instances must be closed because they are added to the event loop
queue by previous `uv_pipe_init()` calls
The `vim_feedkeys` must be deferred because it can potentially free the buffer
passed to `os_inchar`(which in turns calls `vim_feedkeys` indirectly).
The new `vim_input` function can be used to emulate user input(Since it does not
mess with the typeahead, it is safe to execute without deferring).
- Extract `process_interrupts` out of `convert_input`
- Instead of waiting for os_breakcheck/os_inchar calls, call `convert_input`
and `process_interrupts` directly from the read callback in input.c.
- Remove the `settmode` calls from `job_wait`. Now that interrupts are
processed in the event loop, there's no need to set the terminal to cooked
which introduces other problems(ref 7.4.427)
Since the introduction of the FOR_ALL_BUFFERS macro, 'sign unplace id'
without a buffer was only removing the sign from the first buffer rather
than all buffers, as described in the documentation.

The JobEvent structure may refer to a job after it has been freed. Apply
@tarruda's patch to extract the job data before pushing the event.
Also, fix the type, "data" -> "job", in on_job_exit() and free the job
name in the last job event.
- Expose more logging control from the log.c module(get log stream and omit
newlines)
- Remove logging from the generated functions in msgpack-gen.lua
- Refactor channel.c/helpers.c to log every msgpack-rpc payload using
msgpack_object_print(a helper function from msgpack.h)
- Remove the api_stringify function, it was only useful for logging msgpack-rpc
which is now handled by msgpack_object_print.
It's possible that a child process won't close it's standard streams, even after
it exits. This can be evidenced with the "xclip" program:
:call system('xclip -i -selection clipboard', 'DATA')
Before this commit, the above command wouldn't return, even though the xclip
program had exited. That is because `xclip` wasn't closing it's stdout/stderr
streams, which would block pending_refs from ever reaching 0.
Now the job.c module was refactored to ensure all streams are closed when the
uv_process_t handle is closed.
When stdio was closed, parse_msgpack was called with eof == true, with caused a
free_channel call. To ensure the correct behavior for all types of channels, the
close_channel must be called before free_channel.
