6009492e73 Detect AppImage and update executable environment if required 
If starting a process while running from within AppImage adjust
the LD_LIBRARY_PATH of the subprocess when the executable exists
outside of the AppImage. This prevents issues of invalid dynamic
library lookups when the AppImage contains common named libraries.

ceb69e6266 Allow closing a Vagrant::Util::Subprocess's STDIN 
Previously, there was no way to close the STDIN stream of a subprocess,
so commands that read from stdin in a subprocess would hang forever,
such as `/bin/sh -s`. If one tried to close the stdin, the
IO.select() call in Subprocess#execute would raise an error for calling
select() on a closed IO.

Here's a concrete example of a command that needs to close STDIN to work
properly:

```ruby
script = SOME_VERY_LONG_STRING
command = %w(ssh foo.example.com /bin/sh -s foo bar)
result = ::Vagrant::Util::Subprocess.execute(*command) do |type, data_or_io|
  if type == :stdin
    data_or_io.write(script)
    data_or_io.write("\n")
    data_or_io.close
    next
  end

  puts "Remote: #{data_or_io}"
end
```

c72c8dce40 Selecting for duration of timeout can cause hang 
When specifying a timeout, the subprocess used to select for timeout seconds on the stdout, stderr pipes.

This creates a race condition and can cause the `Subprocess#execute` to hang for the full timeout interval if the process has already exited and no more output is send to the pipes.

This race is happening with a higher probability if the subprocess is generating a lot of output.

Mitchell Hashimoto
1a6ae81aa9 Require what to be notified for with block and Subprocess.execute 
There was an issue before where the stdin buffer would always have space
so it would always yield that block and Ruby would spin at 100%. Now we
require all callers to say what they want to listen for. This drops
CPU down to almost nothing.
