We're hoping to add some new commands that don't have any args so this
PR will enable that by removing all of the hard-coded checks that require
commands to have at least one arg. It also adds some checks to each
command so we're consistent in the error message we get. Added a test
for this too.
We actually had this check in at least 3 different places (twice in the
parser and once in most cmds), this removes 2 of them (the parser ones).
Had to remove/modify some testcases because its now legal to have certain
commands w/o args - e.g. RUN. This was actually inconsistent because
we used to allow "RUN []" but not "RUN" even though they would generate
(almost) the same net result. Now we're consistent.

Per Erikh's suggestion at:
https://github.com/docker/docker/pull/9989#issuecomment-69832009
this PR will trim spaces in the parser to ensure that the user gets the same
results irrespetive of leading/trailing spaces.
Per @tiborvass's suggestion I added a test to make sure spaces in quotes
are not touched.

Adjust builder to validate that JSON in Dockerfiles are arrays of strings and nothing else to match how we describe them to people (and what all our existing tests already assumed)

This also adds more tests to help verify this, including unicode and nonprintable characters (hence the earlier commit switching to strconv.Quote).
As a bonus, this fixes a subtle bug where [] was turned into [""] and then turned back into [] (and thus [""] was impossible to actually round-trip correctly in a Dockerfile).

still supports the old form: ENV name value
Also, fixed an issue with the parser where it would ignore lines
at the end of the Dockerfile that ended with \

So far, it looks like the declarations are not used, and so its safer not to
confuse people into thinking they do something.

If previous line ends with whitespace, or next line starts with whitepsace
we need to preserve a space otherwise things line:
RUN echo\
hello
will appear as: RUN echohello
Noticed this while looking at #5744 because he had lines ending in &&\
