This adds a new argument and feature, 'check-file', which will allow
checkpatch to run against files instead of only against patches.

The regex for the if/for/while bracket tests fails to distinguish
non-space text. This means text such as do_something_if() would match
incorrectly.
Additionally, the ends-with-bracket test doesn't allow for the common
coding paradigm:
if (condition) { /* Text about conditional. */
}
So fix that as well.

When no 'Signed-off-by' tags are found, the output will look like:
E: No signatures found.
E: Too many signoffs; are you missing Co-authored-by lines?
Warnings: 0, Errors: 2
However, there should really only be one error reported in this case.

The line numbers being printed were the line numbers for the patchfile.
This is sometimes okay to fix simple things (trailing or leading
whitespace, missing signoffs, etc). But more complicated fixes, or
those fixes which require a bit more care, aren't helped by this. So,
we use the implied file line number.
This can be useful with future work to 'mock' apply and build a real
contextual scanner for checking multi-line changes.

These coding issues are not just things that shouldn't be done. They are
styles which should never be submitted.

This makes it easier to distinguish between the line, and

Teach checkpatch.py to understand that if/for/while blocks should always
end with braces on the same line (if possible). This does not address
multi-line if/for/while blocks, but provides a point where such blocks
could be added.

CodingStyle.md says:
"Use form feeds (control+L) to divide long source files into logical
pieces. A form feed should appear as the only character on a line."
checkpatch.py currently complains about form feed. For example, on
commit 2c06d9a927c5("ovstest: Add test-netlink-conntrack command."),
checkpatch.py returns:
W(140): Line has non-spaces leading whitespace
W(140): Line has trailing whitespace
+
W(177): Line has non-spaces leading whitespace
W(177): Line has trailing whitespace
+
W(199): Line has non-spaces leading whitespace
W(199): Line has trailing whitespace
+
This commit suppresses the two warnings for lines with form feeds as the
only character.

Although tests ideally also stick to shorter line lengths, it is very
common for fixed text blocks like flows or large packets to be specified
within tests. Checkpatch shouldn't complain about cases like these.

Most projects have a checkpatch facility, which can be used as a pre-commit
sanity check. This introduces such a mechanism to the Open vSwitch project
to catch some of the more silly formatting mistakes which can occur. It is
not meant to replace good code review practices, but it can help eliminate
the silly code review issues which get added.
