When using protocol v2 a client constructs a list of ref-prefixes which
are sent across the wire so that the server can do server-side filtering
of the ref-advertisement. The logic that does this exists for both
fetch and push (even though no push support for v2 currently exists yet)
and is roughly the same so lets consolidate this logic and make it
general enough that it can be used for both the push and fetch cases.

Add a --prune-tags option to git-fetch, along with fetch.pruneTags
config option and a -P shorthand (-p is --prune). This allows for
doing any of:
git fetch -p -P
git fetch --prune --prune-tags
git fetch -p -P origin
git fetch --prune --prune-tags origin
Or simply:
git config fetch.prune true &&
git config fetch.pruneTags true &&
git fetch
Instead of the much more verbose:
git fetch --prune origin 'refs/tags/*:refs/tags/*' '+refs/heads/*:refs/remotes/origin/*'
Before this feature it was painful to support the use-case of pulling
from a repo which is having both its branches *and* tags deleted
regularly, and have our local references to reflect upstream.
At work we create deployment tags in the repo for each rollout, and
there's *lots* of those, so they're archived within weeks for
performance reasons.
Without this change it's hard to centrally configure such repos in
/etc/gitconfig (on servers that are only used for working with
them). You need to set fetch.prune=true globally, and then for each
repo:
git -C {} config --replace-all remote.origin.fetch "refs/tags/*:refs/tags/*" "^\+*refs/tags/\*:refs/tags/\*$"
Now I can simply set fetch.pruneTags=true in /etc/gitconfig as well,
and users running "git pull" will automatically get the pruning
semantics I want.
Even though "git remote" has corresponding "prune" and "update
--prune" subcommands I'm intentionally not adding a corresponding
prune-tags or "update --prune --prune-tags" mode to that command.
It's advertised (as noted in my recent "git remote doc: correct
dangerous lies about what prune does") as only modifying remote
tracking references, whereas any --prune-tags option is always going
to modify what from the user's perspective is a local copy of the tag,
since there's no such thing as a remote tracking tag.
Ideally add_prune_tags_to_fetch_refspec() would be something that
would use ALLOC_GROW() to grow the 'fetch` member of the 'remote'
struct. Instead I'm realloc-ing remote->fetch and adding the
tag_refspec to the end.
The reason is that parse_{fetch,push}_refspec which allocate the
refspec (ultimately remote->fetch) struct are called many places that
don't have access to a 'remote' struct. It would be hard to change all
their callsites to be amenable to carry around the bookkeeping
variables required for dynamic allocation.
All the other callers of the API first incrementally construct the
string version of the refspec in remote->fetch_refspec via
add_fetch_refspec(), before finally calling parse_fetch_refspec() via
some variation of remote_get().
It's less of a pain to deal with the one special case that needs to
modify already constructed refspecs than to chase down and change all
the other callsites. The API I'm adding is intentionally not
generalized because if we add more of these we'd probably want to
re-visit how this is done.
See my "Re: [BUG] git remote prune removes local tags, depending on
fetch config" (87po6ahx87.fsf@evledraar.gmail.com;

Access the "remote" variable passed to the fetch_one() directly rather
than through the gtransport wrapper struct constructed in this
function for other purposes.
This makes the code more readable, as it's now obvious that the remote
struct doesn't somehow get munged by the prepare_transport() function
above, which takes the "remote" struct as an argument and constructs
the "gtransport" struct, containing among other things the "remote"
struct.
A subsequent change will copy this pattern to access a new
remote->prune_tags field, but without the use of the gtransport
variable. It's useful once that change lands to see that the two
pieces of code behave exactly the same.
This pattern of accessing the container struct was added in
737c5a9cde ("fetch: make --prune configurable", 2013-07-13) when this

Stop redundantly NULL-ing the last element of the refs structure,
which was retrieved via calloc(), and is thus guaranteed to be
pre-NULL'd.
This code dates back to b888d61c83 ("Make fetch a builtin",
2007-09-10), where wasn't any reason to do this back then either, it's
just boilerplate left over from when git-fetch was initially
introduced.
The motivation for this change was to make a subsequent change which
would also modify the refs variable smaller, since it won't have to
copy this redundant "NULL the last + 1 item" pattern.
We may not end up keeping that change, but as this pattern is still
