[PATCH] sha1_file: make read_info_alternates static

[Stefan Beller <sbeller@google.com>]

read_info_alternates is not used from outside, so let's make it static.

We have to declare the function before link_alt_odb_entry instead of
moving the code around, link_alt_odb_entry calls read_info_alternates,
which in turn calls link_alt_odb_entry.

  This helps in a later refactoring (moving the object
  store to the_repository struct), too.
  
  Thanks,
  Stefan
