The MRU cache that keeps track of recently used packs is represented
using two global variables:
struct mru packed_git_mru_storage;
struct mru *packed_git_mru = &packed_git_mru_storage;
Callers never assign to the packed_git_mru pointer, though, so we can
simplify by eliminating it and using &packed_git_mru_storage (renamed
to &packed_git_mru) directly. This variable is only used by the
packfile subsystem, making this a relatively uninvasive change (and
any new unadapted callers would trigger a compile error).
Noticed while moving these globals to the object_store struct.

This function needs to be global as it is used by sha1_file.c and will
be used by packfile.c.

Both sha1_file.c and packfile.c now need read_object(), so a copy of
read_object() was created in packfile.c.
This patch makes both mark_bad_packed_object() and has_packed_and_bad()
global. Unlike most of the other patches in this series, these 2
functions need to remain global.

The function open_packed_git() needs to be temporarily made global. Its

sha1_file.c declares some static variables that store packfile-related
state. Move them to packfile.c.
They are temporarily made global, but subsequent commits will restore
their scope back to static.

Currently, sha1_file.c and cache.h contain many functions, both related
to and unrelated to packfiles. This makes both files very large and
causes an unclear separation of concerns.
Create a new file, packfile.c, to hold all packfile-related functions
currently in sha1_file.c. It has a corresponding header packfile.h.
In this commit, the pack name-related functions are moved. Subsequent
commits will move the other functions.
