Remove the editor modeline blocks from the source files in ui that use 4
space indentation by running
perl -i -p0e 's{ \n+ /[ *\n]+ editor \s+ modelines .* shiftwidth= .* \*/ \s+ } {\n}gsix' $( ag -l shiftwidth=4 $( ag -g '\.(c|cpp|h|m|mm)') )
This gives us one source of indentation truth for these files, and it
*shouldn't* affect anyone since
- These files match the default in our top-level .editorconfig.
- The one notable editor that's likely to be used on these files and
*doesn't* support EditorConfig (Qt Creator) defaults to 4 space
indentation.
In dumpcap, if we're being run by TShark or Wireshark, if there are no
link-layer types, just provide an empty list to our caller; let them
construct an empty list of link-layer types when they read our output.
In the code that reads that list, don't report an error if the list is
empty, rely on the caller to do so.
Have capture_opts_print_if_capabilities() do more work, moving some
functions from its callers to it.
"Commonly-used" meaning "used by more than one source file".
Clean up the exit codes, combining some duplicates with different names,
and using some instead of raw numbers in some places.
