Jonathan Tan fdb69d33c4 fetch-pack: always allow fetching of literal SHA1s
fetch-pack, when fetching a literal SHA-1 from a server that is not
configured with uploadpack.allowtipsha1inwant (or similar), always
returns an error message of the form "Server does not allow request for
unadvertised object %s". However, it is sometimes the case that such
object is advertised. This situation would occur, for example, if a user
or a script was provided a SHA-1 instead of a branch or tag name for
fetching, and wanted to invoke "git fetch" or "git fetch-pack" using
that SHA-1.

Teach fetch-pack to also check the SHA-1s of the refs in the received
ref advertisement if a literal SHA-1 was given by the user.
