[PATCH v2 0/4] 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.

v2:
 * Dropped patches already merged
 * Rebased on Stefano's series of lint fixes
 * Add a missing #include in 1/4 and 2/4
 * Adjust 3/4 not to die if close_range() is unavailable

David Gibson (4):
  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
  cppcheck: Don't check the system headers
