If a builtin uses RUN_SETUP to request that git.c enter the repository
directory, we'll get passed in a "prefix" variable with the path to the
original directory. It's important to pass this to parse_options(),
since we may use it to fix up relative OPT_FILENAME() options. Some
builtins don't bother; let's make sure we do so consistently.
There may not be any particular bugs fixed here; OPT_FILENAME is
actually pretty rare, and none of these commands use it directly.
However, this does future-proof us against somebody adding an option
that uses it and creating a subtle bug that only shows up when you're in
a subdirectory of the repository.
In some cases, like hash-object and upload-pack, we don't specify
RUN_SETUP, so we know the prefix will always be empty. It's still worth
passing the variable along to keep the idiom consistent across all
builtins (and of course it protects us if they ever _did_ switch to
using RUN_SETUP).

This was added as a NEEDSWORK in c3c36d7de2 (replace-object:
check_replace_refs is safe in multi repo environment, 2018-04-11),
waiting for a calmer period. Since doing so now doesn't conflict
with anything in 'pu', it seems as good a time as any.

The beginning of the next-gen transfer protocol.
* bw/protocol-v2: (35 commits)
remote-curl: don't request v2 when pushing
remote-curl: implement stateless-connect command
http: eliminate "# service" line when using protocol v2
http: don't always add Git-Protocol header
http: allow providing extra headers for http requests
remote-curl: store the protocol version the server responded with
remote-curl: create copy of the service name
pkt-line: add packet_buf_write_len function
transport-helper: introduce stateless-connect
transport-helper: refactor process_connect_service
transport-helper: remove name parameter
connect: don't request v2 when pushing
connect: refactor git_connect to only get the protocol version once
fetch-pack: support shallow requests
fetch-pack: perform a fetch using v2
upload-pack: introduce fetch server command
push: pass ref prefixes when pushing
fetch: pass ref prefixes when fetching
ls-remote: pass ref prefixes when requesting a remote's refs
transport: convert transport_get_remote_refs to take a list of ref prefixes
...
Teach the client to be able to request a remote's refs using protocol
v2. This is done by having a client issue a 'ls-refs' request to a v2
server.

Introduce protocol_v2, a new value for 'enum protocol_version'.
Subsequent patches will fill in the implementation of protocol_v2.
