Subject: [PATCH v2 0/9] kbuild: clang-tidy

I improved gen_compile_commands.py,
then rebased Nathan's v7 [1] on top of them.
To save time, I modified the Makefile part.
No change for run-clang-tools.py

"make clang-tidy" should work in-tree build,
out-of-tree build (O=), and external module build (M=).

This version keeps the previous work-flow.
You can still manually run scripts/gen_compile_commands.json

'make compile_commands.json' or 'make clang-tidy' is handier
for most cases. As Nick noted, there is 3 % loss of the coverage.

If you need the full compilation database that covers all the
compiled C files, please run the script manually.

  gen_compile_commands: parse only the first line of .*.cmd files
  gen_compile_commands: use choices for --log_levels option
  gen_compile_commands: do not support .cmd files under tools/ directory
  gen_compile_commands: reword the help message of -d option
  gen_compile_commands: make -o option independent of -d option
  gen_compile_commands: move directory walk to a generator function
  gen_compile_commands: support *.o, *.a, modules.order in positional
    argument
  kbuild: wire up the build rule of compile_commands.json to Makefile
