[PATCH 05/14] upload-pack: move shallow_nr to upload_pack_data

[Christian Couder <christian.couder@gmail.com>]

As we cleanup 'upload-pack.c' by using 'struct upload_pack_data'
more thoroughly, let's move the 'shallow_nr' static variable
into this struct.

It is used by code common to protocol v0 and protocol v2.
