The existing behavior relies on patch context to identify function
declarations.  Add the ability to find function declarations when there
is an open brace in column 1.

This finds function declarations only in specific single line forms
where the function name is on a single line like:

  int foo(args...)
  {

and

  int
  foo(args...)
  {

It does not recognize function declarations like:

  int foo(int bar,
          int baz)
  {

Lines containing "} else {" should not be detected as unbalanced braces.
But the second check can be reduced to ".+else\s*{" and it therefore
never checked if the beginning of a line contains any other character
(like the relevant "}").  This check would also return true for "} else
{" and create warnings like

    CHECK: Unbalanced braces around else statement
    #391: FILE: ./net/batman-adv/tvlv.c:391:

The check can be changed to check the whole line for the missing "}" to
avoid this false positive.

Signoff was not checked if the filename is '-', indicating reading the
patch from stdin.  Commands such as the below would not warn about a
missing signoff, because the patch filename is '-'.  This change allows
checkpatch to warn about a missing signoff, even if the input filename
is '-', but only if the patch has a commit message.

  git show --pretty=email | scripts/checkpatch.pl -

A more common use of checkpatch with stdin is for piping git diff
through checkpatch.  The diff output would not contain a commit message,
and therefore it would not contain a signoff line.  For this common use
case, a warning should not be printed about the missing signoff.  With
this change we will only warn about a missing signoff if the input
contains a commit message.

  git diff | scripts/checkpatch.pl -

Before this patch, a workaround for the first command was to refer to
stdin by a name other than '-'.  The workaround is not an elegant
solution, because elsewhere checkpatch uses the fact that filename
equals '-', such as in setting '$vname' to 'Your patch' for stdin.  The
command below would report "/dev/stdin has style problems" instead of
"Your patch has style problems."

  git show --pretty=email | scripts/checkpatch.pl /dev/stdin
