When rbenv is used for managing Ruby installations, just checking for an
executable called "neovim-ruby-host" is not enough. It has to be run as well.
If it does not return 0, then neovim-ruby-host is merely a shim for another Ruby
installation.
$ rbenv versions
2.5.0
* 2.5.1 (set by /Users/mhi/.rbenv/version)
$ rbenv whence neovim-ruby-host
2.5.0
$ which neovim-ruby-host
/Users/mhi/.rbenv/shims/neovim-ruby-host
$ neovim-ruby-host
rbenv: neovim-ruby-host: command not found
The `neovim-ruby-host' command exists in these Ruby versions:
2.5.0
$ echo $?
127
Additionally, the detection logic was moved from provider#ruby#Detect() to
s:detect(), because the former is run in the sandbox which forbids calling
system().
If `jobstart()` fails, then the subsequent `rpcrequest()` will throw due
to an invalid channel id. This causes `job.stderr` not to exist, so we
throw another exception when trying to dump the job's stderr.

This obfuscates the actual problem.
On some versions of macOS, pbcopy doesn't work in tmux <2.6
https://superuser.com/q/231130
Fallback to tmux in that case.
Add a healthcheck for this scenario.
For back-compat, :CheckHealth runs :checkhealth. But don't define
:CheckHealth explicitly, it adds noise to wildmenu completion.
Completion of healthchecks doesn't yet work with :checkhealth, this is
a regression but it needs to be implemented for :checkhealth rather than
keeping :CheckHealth around.
ci: install nodejs 8 in Appveyor, Travis
provider: check node version for debug support
Resolve https://github.com/neovim/neovim/pull/7577#issuecomment-350590592 for Unix.
provider: test if nodejs in ci supports --inspect-brk
nodejs host for neovim requires nodejs 6+ to work properly.
nodejs 6.12+ or 7.6+ is required for debug support via `node --inspect-brk`.
provider: run cli.js of nodejs host directly
npm shims are useless because the user cannot set node to debug mode via
--inspect-brk. This is problematic on Windows which use batchfiles and
shell scripts to compensate for not supporting shebang.
The patch uses `npm root -g` to get the absolute path of the global npm
modules. If that fails, then the user did not install neovim npm package
globally. Use that absolute path to find `neovim/bin/cli.js`, which is
what the npm shim actually runs with node. glob() is for a simple file
check in case bin/ is removed because the npm shims are ignored now.
ruby uses batchfiles with 'cmd' extension.
gem creates batchfiles with 'bat' extension.
`gem install rails` does the following in Windows (not Cygwin):
1. Run `gem.cmd install rails` on cmd.exe
2. gem.cmd runs `ruby.exe -x gem install rails`
3. `rails` gem is installed.
`rails.bat` is created in the same directory
where ruby.exe and gem.cmd reside.
neovim-ruby-host is a ruby script.
neovim-node-host is a shell script.
Both don't work in cmd.exe so gem and npm provide batchfile shims.
Return the full path of these shims, cmd.exe knows better what to do with these files.
- Show hint only once per session.
- provider#clipboard#Call(): prevent recursion
- provider#clear_stderr(): use has_key(), because :silent! is still
captured by :redir.

redir_write():
- This is a "batch" operation which was not yet covered by
start_batch_changes()
adjust_clipboard_name():
- msg() and friends during :redir will, of course, cause redir_write()
to try to capture that message, which causes recursion.
- EMSG() here is trouble: if it interrupts :redir it is a mess.
Rather than deal with the mess, show a non-error message.

This allows users who have per-project Ruby versions (e.g. with `rvm`)
to pin to a particular gem installation.
For example: `let g:ruby_host_prog = 'rvm system do neovim-ruby-host'`

This commit assumes Ruby 2.0.0+.
The exists('g:loaded_foo') convention is rather common, and may be
relied upon in some cases. It's also very unlikely that a user or plugin
has any reason to set g:loaded_foo to zero, so the principle of least
surprise can be brushed aside here.

This option simplifies the configuration options:
1) `g:python{,3}_host_prog` is not set.
Neovim tries its best to find a suitable interpreter. This means calling
exepath(), potentially multiple times, and a system('python -c ...') with
the first found interpreter, to get the Python version.
2) `g:python{,3}_host_prog` is set.
Avoids everything of the above. No safety checks, no training wheels. Fast
host startup time!
Never throw an error when provider/clipboard.vim is sourced for the first time.
Save the error instead and expose it via `provider#clipboard#Error()`, mimicking
provider/python.vim.
