Attributes can be specified at three different places: the internal
table of default values, the file $GIT_DIR/info/attributes and files
named .gitattributes in the work tree. Since bare repositories don't
have a work tree, git should ignore any .gitattributes files there.
This patch makes git do that, so the only way left for a user to specify
attributes in a bare repository is the file info/attributes (in addition
to changing the defaults and recompiling).
In addition, git-check-attr is now allowed to run without a work tree.
Like any user of the code in attr.c, it ignores the .gitattributes files
when run in a bare repository. It can still read from info/attributes.

Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.
This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".
On systems with a less-capable diff, you can do:
GIT_TEST_CMP=cmp make test

There was an embarrassing pair of off-by-one miscounting that
failed to match path "a/b/c" when "a/.gitattributes" tried to
name it with relative path "b/c".
This fixes it.
