[RFC PATCH 3/4] .clang-format: do not enforce a ColumnLimit

Our Documentation/CodingGuidelines mention that "We try to keep to at
most 80 characters per line", but in reality we have a lot of code
that runs afoul of that rule.

Before & after this change running "make style-all-diff-apply" will
yield:

	579 files changed, 32065 insertions(+), 29818 deletions(-)
	509 files changed, 13042 insertions(+), 12745 deletions(-)

As with the preceding change what this leaves us with an unresolved
question though, should we have some stricter version of "make
style-all" that incorporates "ColumnLimit: 80", or perhaps apply it
only on "make style", but then what if someone modifies code that
happens to e.g. search/replace a line running afoul of the limit?
