Describe the fallthrough pseudo-keyword.
Convert the coding-style.rst example to the keyword style.
Add description and links to deprecated.rst.
Miguel Ojeda comments on the eventual [[fallthrough]] syntax:
"Note that C17/C18 does not have [[fallthrough]].
C++17 introduced it, as it is mentioned above. I would keep the
__attribute__((fallthrough)) -> [[fallthrough]] change you did,
though, since that is indeed the standard syntax (given the paragraph
references C++17).
I was told by Aaron Ballman (who is proposing them for C) that it is
more or less likely that it becomes standardized in C2x. However, it
is still not added to the draft (other attributes are already,
though). See N2268 and N2269:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2268.pdf (fallthrough)
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2269.pdf (attributes in general)"

Now that all the fall-through warnings have been addressed in the
kernel, enable the fall-through warning globally.
Also, update the deprecated.rst file to include implicit fall-through
as 'deprecated' so people can be pointed to a single location for
justification.

As discussed in the "API replacement/deprecation" thread[1], this makes
an effort to document what things shouldn't get (re)added to the kernel,
by introducing Documentation/process/deprecated.rst.
