[PATCH v2 0/3] devtool: fix standalone clone conversion for nested git repos

[Jamin Lin <jamin_lin@aspeedtech.com>]

When a recipe has multiple git SRC_URI entries with destsuffix values
nested inside S, devtool modify left all but the top-level repo with a
.git/objects/info/alternates file pointing into the downloads cache.

Running 'bitbake -c cleanall' then removed those shared objects, breaking
all subsequent git operations in the workspace.
Fix git_convert_standalone_clone() to walk all git repos nested inside S
and repack each one to a fully standalone clone.

v1:
  - Fix git_convert_standalone_clone() to walk all git repos nested
    inside S and repack each one to a standalone clone
v2:
  - Add selftest recipe devtool-test-multi-destsuffix with six nested
    git SRC_URI entries to reproduce the scenario
  - Add test_devtool_modify_multi_git_destsuffix_standalone to verify
    all nested repos have their alternates removed after devtool modify
    and remain usable after 'bitbake -c cleanall'

  scripts/scriptutils: Convert nested git repos to standalone clones in
    devtool workspace
  meta-selftest: Add devtool-test-multi-destsuffix recipe
  oeqa/selftest/devtool: Add test for multiple nested git destsuffix
    repos
