[PATCH 00/12] Minor fixups for or inspired by clangd and related tools

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

I've been experimenting with Zed and clangd recently.  Currently it
generates an enormous number of largely spurious errors and warnings
on the passt code base.  Mostly that's due to its default
configurations not suiting us.  This series adds some configuration
that addresses a number of those warnings, though there remain many
more for now.

Some of the warnings also look reasonable, so I have a grab bag of
fixes or workarounds for some of those two.

David Gibson (12):
  clang: Add .clang-format file
  Makefile: Simplify exclusion of qrap from static checks
  clang: Move clang-tidy configuration from Makefile to .clang-tidy
  arch: Avoid explicit access to 'environ'
  flow: Correct type of flowside_at_sidx()
  netlink: RTA_PAYLOAD() returns int, not size_t
  Makefile: Move NETNS_RUN_DIR definition to C code
  seccomp: Simplify handling of AUDIT_ARCH
  Makefile: Use -DARCH for qrap only
  Makefile: Don't attempt to auto-detect stack size
  clang: Add rudimentary clangd configuration
  util: Remove unused ffsl() function
