Nguyễn Thái Ngọc Duy a60645f9c5 setup: remember whether repository was found ...

As v1.7.2~16^2 (git --paginate: paginate external commands
again, 2010-07-14) explains, builtins (like git config) that
do not use RUN_SETUP are not finding GIT_DIR set correctly when
it is time to launch the pager from run_builtin().  If they
were to search for a repository sooner, then the outcome of such
early repository accesses would be more predictable and reliable.

The cmd_*() functions learn whether a repository was found through the
*nongit_ok return value from setup_git_directory_gently().  If
run_builtin() is to take care of the repository search itself, that
datum needs to be retrievable from somewhere else.  Use the
startup_info struct for this.

As a bonus, this information becomes available to functions such as
git_config() which might want to avoid trying to access a repository
when none is present.
