Since we're about to do a v3.0.0 release, let's bump the version to v3.
Make this change automatically with the following command to avoid any
missed items:
git grep -l github.com/git-lfs/git-lfs/v2 | \
xargs sed -i -e 's!github.com/git-lfs/git-lfs/v2!github.com/git-lfs/git-lfs/v3!g'
When our go.mod file was introduced in commit
114e85c2002091eb415040923d872f8e4a4bc636 in PR #3208, the module
path chosen did not include a trailing /v2 component. However,
the Go modules specification now advises that module paths must
have a "major version suffix" which matches the release version.
We therefore add a /v2 suffix to our module path and all its
instances in import paths.
See also https://golang.org/ref/mod#major-version-suffixes for
details regarding the Go module system's major version suffix rule.
The original parser that was used in #3825 brings in a lot of
dependencies that complicate packaging git-lfs. This replaces it with a
small parser I wrote with almost no dependencies. I've tested this as
extensively as i can and it seems to work correctly.
