Fixes#2060
When a command sets `DisableFlagParsing = true` it requests the
responsibility of doing all the flag parsing. Therefore even the
`--help/-f/--version/-v` flags should not be automatically completed
by Cobra in such a case.
Without this change the `--help/-h/--version/-v` flags can end up being
completed twice for plugins: one time from cobra and one time from the
plugin (which has set `DisableFlagParsing = true`).

Fixes#1816
Previously, arguments with a dash as the second character (e.g., 1-ff00:0:1)
were detected as a flag by mistake. This resulted in auto completion misbehaving
if such an argument was last in the argument list during invocation.
Fixes#1786
The --help, -h, --version and -v flags are normally added when the
`execute()` function is called on a command. When doing completion
we don't call `execute()` so we need to add these flags explicitly to
the command being completed.
Also, we disable all further completions if the 'help' or 'version'
flags are present on the command-line.

Fixes#1562
Programs that don't have sub-commands can accept any number of args.
However, when doing shell completion for such programs, within the
__complete code this very __complete command makes it that the program
suddenly has a sub-command, and the call to Find() -> legacyArgs() will
then return an error if there are more than one argument on the
command-line being completed.
To avoid this, we first remove the __complete command in such a case so
as to get back to having no sub-commands.

When a command has set DisableFlagParsing=true, it means Cobra should
not be handling flags for that command but should let the command
handle them itself. In fact, Cobra normally won't have been told at all
about flags for this command.
Not knowing about the flags of the command also implies that Cobra
cannot perform flag completion as it does not have the necessary info.
This commit still tries to do flag name completion, but when
DisableFlagParsing==true, it continues on so that ValidArgsFunction will
be called; this allows the program to handle completion for its own
flags when DisableFlagParsing==true.

* Fix flag completion
The flag completion functions should not be stored in the root cmd.
There is no requirement that the root cmd should be the same when
`RegisterFlagCompletionFunc` was called. Storing the flags there does
not work when you add the the flags to your cmd struct before you add the
cmd to the parent/root cmd. The flags can no longer be found in the rigth
place when the completion command is called and thus the flag completion
does not work.
Also #1423 claims that this would be thread safe but we still have a map
which will fail when accessed concurrently. To truly fix this issue use a
RWMutex.

If the interspersed option is set false and one arg is already set all
following arguments are counted as arg and not parsed as flags. Because
of that we should not offer flag completion. The same applies to arguments
followed after `--`.

This v2 version of bash completion is based on Go completions.
It also supports descriptions like the other shells.

Flag definitions like `-asd` are not handled correctly by
the custom completion logic. They should be treated as
multiple flags. For details refer to #1257.

Make it easier for programs to provide shell completion by creating
the 'completion' command automatically.
If a 'completion' command is already provided by the program, Cobra
will use that one instead.
