wireprotov1peer: update all rpcs to use the new batchable scheme If desired, we could keep the future class and the function that upgrades an old style rpc instead of a new style, for extensions. Differential Revision: https://phab.mercurial-scm.org/D11212

wireprotov1peer: simplify the way batchable rpcs are defined The scheme with futures/generator is confusing due to the way communication is done by side effects, especially with two different "future" objects. Just returning a request and a function to read the response is easier to understand. There are tests failures with the largefiles extension due to it aliasing one rpc to another one, which gets fixed in the next commit. Differential Revision: https://phab.mercurial-scm.org/D11211

clone: properly create target directories during local clone (issue6581) The store encoding was mudding the water. This lead to local clone crashing for file with long filename as their destination directory needed to be encoded. Differential Revision: https://phab.mercurial-scm.org/D11340

clone: add a file demonstrating issue6581 in test-clone-stream.t This is quite noisy so we adds it in its own changeset. Fixes for the issue are coming in the next patch. Differential Revision: https://phab.mercurial-scm.org/D11339
