[PATCHv2 10/36] attr: rename function and struct related to checking attributes

[Stefan Beller <sbeller@google.com>]

From: Junio C Hamano <gitster@pobox.com>

The traditional API to check attributes is to prepare an N-element
array of "struct git_attr_check" and pass N and the array to the
function "git_check_attr()" as arguments.

In preparation to revamp the API to pass a single structure, in
which these N elements are held, rename the type used for these
individual array elements to "struct git_attr_check_elem" and rename
the function to "git_check_attrs()".
