Re: split bootstrap in two phases, GNU wget2

[Bruno Haible]

Hi dear GNU wget developers (Tim et al.),

The 'bootstrap' script from Gnulib has been reorganized to work in two phases:
  (1) Fetch auxiliary files that are not in the git checkout.
      This is the part that requires network access and that has
      supply-chain concerns.
  (2) Generate files such as configure, config.h, Makefile.in etc.
      This includes running gnulib-tool.

See <https://lists.gnu.org/archive/html/bug-gnulib/2022-07/msg00053.html> for
details.

For GNU wget2 some adjustment of the bootstrap.conf is needed: The clone_wiki
invocation, which makes network accesses, needs to be moved from the
bootstrap_post_import_hook to the bootstrap_post_pull_hook.

This adjustment will be needed the next time you use the '--bootstrap-sync'
option.
