Remove some unused historical files.
Aggressively disable warnings to keep the lemon source
pristine and avoid the maintenance burden for lemon itself.
Lemon has its own lax policy for warnings that doesn't match our
own and they won't accept external patches to remove the
warnings, so just ignore them. Lemon is just executed to generate
code for the Wireshark build and the minor code issues it has
have no influence at runtime.
For lemon generated code we selectively disable some linting
warnings.
Remove patches for lemon and lempar, they are no longer required
with these changes to silence warnings.
Repeated words were found with:
egrep "(\b[a-zA-Z]+) +\1\b" . -Ir
and then manually reviewed.
Non-displayed strings (e.g., in comments)
were also corrected, to ease future review.
The distinction between the different kinds of capture utility
may not warrant a special subfolfer for each, and sometimes the
distinction is not be clear or some functions could stradle
multiple "categories" (like capture_ifinfo.[ch]).
Simplify by having only a generic 'capture' subfolder. The
separate CMake libraries are kept as a way to reuse object code
efficiently.
