This conversion was done without the #define trick used in the earlier

MIME-Version: 1.0

This conversion was done without the #define trick used in the earlier
series refactoring to have better repository access, because this function
is easy to review, as it only has one caller and all lines but the first
two are converted.

We must not convert 'pack_open_fds' to be a repository specific variable,
as it is used to monitor resource usage of the machine that Git executes
on.

Subject: packfile: add repository argument to prepare_packed_git
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a repository argument to allow prepare_packed_git callers to be
more specific about which repository to handle. See commit "sha1_file:
add repository argument to link_alt_odb_entry" for an explanation of
the #define trick.

Subject: packfile: keep prepare_packed_git() private
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The reason callers have to call this is to make sure either packed_git
or packed_git_mru pointers are initialized since we don't do that by
default. Sometimes it's hard to see this connection between where the
function is called and where packed_git pointer is used (sometimes in
separate functions).

Keep this dependency internal because now all access to packed_git and
packed_git_mru must go through get_xxx() wrappers.
