feeds: use git-src-full to allow Git versioning

[aparcar]

Both $(AUTORELEASE) and $(PKG_SRC_VERSION) (from luci.git) use the Git
log to determine releases and package timestamps.

Feeds are shallow cloned by default, resulting in an incomplete Git log
and therefore different local package versions than offered upstream.

This commits sets the default feeds to use src-git-full to solve that.

Please also fix the git pull --ff-only usage (in three places in src-git-full).

I only fixed the traditional src-git with #3610 / commit 2b1d92f
but the src-git-full remained unfixed at that time.

[aparcar]

Done.

How about an alternative approach: instead of editing the feeds definition files, just rename the src-git variants in script/feeds:
src-git-full --> src-git
src-git --> src-git-shallow (or src-git-small)

That way the feeds.conf.default would not need to be changed, as just the behaviour of src-git would change for future clones.

This should likely be backported also into 21.02, where AUTORELEASE is already used.

Ps.
To mitigate the change for the (likely really small) minority who have used src-git-full in their local feed definitions, there might be an "or" in style of
'src-git' => {
changed to
('src-git' or 'src-git-full') => {

(Not sure about the correct perl syntax...)

@aparcar
Are you proceeding with this?

[aparcar]

Thanks for the reminder, I'll do that later today!

[aparcar]

I'm somewhat against "forcing" that behavior onto users, I'd just proceed with the change suggested and future setup start using it. Especially CI would get "fixed" by this.

[hnyman]

Your original approach is just fine. ;-)
