This reverts part of ade88fe4c [1].
This is required for `let g:python3_host_prog = 'python'` etc, where it
should get picked up from PATH.
Without this it would show:
```
- INFO: pyenv: Path: /home/user/.pyenv/libexec/pyenv
- INFO: pyenv: Root: /home/user/.pyenv
- INFO: Using: g:python3_host_prog = "python"
- ERROR: "python" was not found.
- INFO: Executable: Not found
- ERROR: Detected pip upgrade failure: Python executable can import "pynvim" but not "neovim": python
- ADVICE:
- Use that Python version to reinstall "pynvim" and optionally "neovim".
pip3 uninstall pynvim neovim
pip3 install pynvim
pip3 install neovim # only if needed by third-party software
```
Note that it additionally causes a weird error
("Detected pip upgrade failure"), due to `s:check_bin` emptying
`python_exe` (because the non-absolute file not being readable), and
`provider#pythonx#DetectByModule('pynvim', a:version)` from 75593e6fce
then just getting the value from the host var again (without actual
checks).
This is implicitly fixed via this patch now (because it is skipped), but
could need some improvement in this regard probably.
With this patch it resolves it (for a virtualenv where pynvim is not
made available intentionally):
```

Instead of deciding provider status in eval_has_provider, move the
decision to the provider Vim scripts.
Previously, provider loading worked as follows:
1. eval_has_provider() verified provider availability by searching for
the provider#providername#Call function and cached this verificaion as a static
variable for some providers
2. providers short-circuited on loading to prevent the definition of the
Call function (with the exception of the node provider that did not)
This commit changes the expected interface between nvim and its
providers to facilitate provider reloading, by splitting the
verification of the provider from the availability of the Call function.
eval_has_provider() now checks for a provider#providername#enabled
variable. It is up to the provider script to set this to 0 or 1
accordingly. eval_call_provider() remains unchanged.
All providers hosting a Call function were updated to respect this.
The clipboard provider now has a Reload function to reload the
provider.
`wl-copy` by default tries to determine the mime type of a copied bit of
text. From the [readme](https://github.com/bugaevc/wl-clipboard):
> wl-copy automatically infers the type of the copied content by running
> xdg-mime(1) on it.
So copying a Ruby script from Nvim may store it in the Wayland clipboard
as mime-type `application/x-ruby`.
This is a small reproduction without Nvim:
$ cat test.rb
#!/usr/bin/env ruby
puts 'hello world'
$ cat test.rb | wl-copy
$ wl-paste --list-types
application/x-ruby
This commit fixes that by telling wl-copy that all text copied from
Nvim has the mime type `text/plain`.
$ cat test.rb | wl-copy --type text/plain
$ wl-paste --list-types
text/plain;charset=utf-8
The neovim module is available for backwards compatibility. We should
not yet force the use of the pynvim module, since there's no other major
reason to bump the minimum supported Python client module.
Closes#9426
Before this commit, if user does this:
let g:node_host_prog = '~/.nvm/versions/node/v11.3.0/bin/neovim-node-host'
the "~/" is not expanded to user's home directory.
`:help g:ruby_host_prog` suggests a path with "~/" so technically we
already claimed to support this.
closes https://github.com/neovim/node-client/issues/102
PR #9304 added support for functions in clipboard providers. As part of
the PR I meant to move two checks in the provider code out of an if
statement into separate statements and adding additional checks for
g:clipboard attributes - as it turns out the code is wrong and it does
not implement additional checks while it adds two conditions that make
very little sense
type(g:clipboard['copy']) #isnot# v:t_func
what would make sense would be something along the lines of
type(g:clipboard['copy']['+']) #isnot# v:t_func
but might not be what we want either, so I'm reverting this.
Up to now g:clipboard["copy"] only supported string values invoked as
system commands.
This commit enables the use of VimL functions instead. The function
signatures are the same as in provider/clipboard.vim. A clipboard
provider is expected to store and return a list of lines (i.e. the text)
and a register type (as seen in setreg()).
cache_enabled is ignored if "copy" is provided by a VimL function.
The order was swapped in #4150 to prefer `xsel` but there wasn't a clear
explanation. Meanwhile, `xsel` has been neglected upstream.
Let's trying preferring `xclip` again, we've had a few reports of
problems with `xsel`.

For each package manager,
1. Check if they are executable before starting a job.
2. Check if the job opts are set before checking the job status
TODO: Validate the job id.
Prioritize npm because it's faster than yarn.
Reindent the code to 2-space indent.
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 $?

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

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.

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.
