Deprecating all C headers

[CursedRock17]

This pull request is another and possibly the last needed addition to complete the breakdown of PR #120 in which all C headers are deprecated to C++ headers to solve this issue:

But there is another problem here, and that is that message_filters isn't a "proper" C++ package. In particular, the header files still have the .h extension, and so our linters consider them to be C headers, not C++ headers

The PR appears to be super messy because I guess renaming files counts as making a whole new file in Git's eyes, but really each old file was renamed to have the .hpp tag with the correct header guard, then a new file .h was created with a warning message to use the C++ style header, so not too bad.

Since this pull request was meant to be the last of pull request #120, I feel we should be able to close both #120 and its respective issue of #29 since linters have been totally added. We just have to revisit this pull request in I believe L-turtle to remove the deprecations.
