[PATCH v7 00/17] propose config-based hooks (part I)

Since v6:

 - Converted 'enum hookdir_opt' to UPPER_SNAKE
 - Coccinelle fix in the hook destructor
 - Fixed a bug where builtin/hook.c wasn't running the default git config setup
   and therefore missed hooks in core.hooksPath when it was set. (These hooks
   would still run except when invoked by 'git hook run' as the config was
   called by the processes which invoked the hook library.)

CI run: https://github.com/nasamuffin/git/actions/runs/436864964

Thanks!
 - Emily
