upload-pack: Implement no-done capability
If the client requests both multi_ack_detailed and no-done then
upload-pack is free to immediately send a PACK following its first
'ACK %s ready' message. The upload-pack response actually winds
up being:
ACK %s common
... (maybe more) ...
ACK %s ready
NAK
ACK %s
PACK.... the pack stream ....
For smart HTTP connections this saves one HTTP RPC, reducing
the overall latency for a trivial fetch. For git:// and ssh://
a no-done option slightly reduces latency by removing one
server->client->server round-trip at the end of the common
ancestor negotiation.
