[PATCH 02/24] init-db, clone: change unnecessary global into passed parameter

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

Much like the former commit, this commit was prompted by a desire to
move the functions which builtin/init-db.c and builtin/clone.c share out
of the former file and into setup.c.  A secondary issue that made it
difficult was the init_shared_repository global variable; replace it
with a simple parameter that is passed to the relevant functions.
