- Making sure the exit code is always zero when we ask for help
- Making sure the exit code isn't zero when we print help on error cases
- Making sure both short and long usage go to the same stream (stdout vs stderr)
- Making sure all docker commands support --help
- Test that all cmds send --help to stdout, exit code 0, show full usage, no blank lines at end
- Test that all cmds (that support it) show short usage on bad arg to stderr, no blank line at end
- Test that all cmds complain about a bad option, no blank line at end
- Test that docker (w/o subcmd) does the same stuff mentioned above properly

An earlier commit was causing docker windows CLI build to not to pick up
the shorthand form for home directory (`%USERPROFILE%`) shown in when
`docker --help` is executed.
Fixing that bug and making the if statement concise and clear.

estesp noticed that when $HOME is / the ~ substitutions messes up
becuase it tries to replace all paths that start with "/" with "~".
This fixes it so that it will only replace it when $HOME isn't "/".

This makes use of `%USERPROFILE%` as a substitute for
`~` on Windows and prints shorter strings for default
cert paths etc.
Also removes string escaping/quotes around default
path values printed in `docker help` command as they
are not really necessary and adds double backslashes
(\\) on windows.

This modifies the "docker help" text so that it is no wider than 80 chars
and each description fits on one line. This will also try to use ~ when
possible
Added a test to make sure we don't go over 80 chars again.
Added a test to make sure we use ~
Applied rules/tests to all docker commands - not just main help text

* Do not log bad options error message twice, e.g.:
$ docker run --pouet
flag provided but not defined: --pouet
See 'docker run --help'.
2014/11/05 21:41:23 flag provided but not defined: --pouet
With this patch just the first two lines will be produced.
* Print 'docker' just once when run without a command, e.g.:
$ docker --hel
flag provided but not defined: --hel
See 'docker docker --help'.

--help and help are successful commands so output should not go to error.
QE teams have requested this change, also users doing docker help | less
or docker run --help | less would expect this to work.
Usage statement should only be printed when the user asks for it.
Errors should print error message and then suggest the docker COMMAND --help
command to see usage information.
The current behaviour causes the user to have to search for the error message
and sometimes scrolls right off the screen. For example a error on a
"docker run" command is very difficult to diagnose.
Finally erros should always exit with a non 0 exit code, if the user
makes a CLI error.

I also needed to add a mflag.IsSet() function that allows you to check
to see if a certain flag was actually specified on the cmd line.
Per #9221 - also tweaked the docs to fix a typo.
Closes#9221
Signed-off-by: Doug Davis <dug@us.ibm.com>
This patch improves the mflag package to ensure that things arguments
to mflag such as `-flag="var"` or `-flag='var'` have the quotes
stripped from the value (to mirror the getopt functionality for similar
flags).
