[PATCH 0/8] Avoid running cppcheck on system headers

[David Gibson <david@gibson.dropbear.id.au>]

It turns out cppcheck has inbuilt knowledge of the C library, and
isn't typically given the system headers.  Avoiding doing so reduces
the runtime to less than half of what it currently is.

For non-obvious reasons, this change also exposes some new warnings.
Some are real, one is a cppcheck bug.  Fix and/or workaround these
then make the change to the cppcheck options.

This is based on my earlier series with clangd configuration and
fixes.

David Gibson (8):
  linux_dep: Generalise tcp_info.h to handling Linux extension
    compatibility
  log: Only check for FALLOC_FL_COLLAPSE_RANGE availability at runtime
  linux_dep: Move close_range() conditional handling to linux_dep.h
  linux_dep: Fix CLOSE_RANGE_UNSHARE availability handling
  ndp: Use const pointer for ndp_ns packet
  udp: Don't dereference uflow before NULL check in
    udp_reply_sock_handler()
  util: Work around cppcheck bug 6936
  cppcheck: Don't check the system headers
