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.
- Show hint only once per session.
- provider#clipboard#Call(): prevent recursion
- provider#clear_stderr(): use has_key(), because :silent! is still
captured by :redir.
closes#7184
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.

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.
This avoids the issue of nvim started daemons causing mountpoints to be
unmountable. This is currently the only place in runtime/ where this
calling convention occurred.

xsel and xcopy may be available even if a valid X display is not. Also,
the availability of X may change at any time, so check on each
invocation.
Closes#1509.
Clipboard is implemented with platform-specific shell commands, and python is
implemented with the external plugin facility (rpc#* functions). The
script_host.py file(legacy python-vim emulation plugin) was moved/adapted from
the python client repository.
