Check local clone

==================

The logic is close enough of uncompressed.

This is present here to reuse the testing around file with "special" names.

  $ hg clone server local-clone

  updating to branch default

  1088 files updated, 0 files merged, 0 files removed, 0 files unresolved

Check that the clone went well

  $ hg verify -R local-clone -q

Check uncompressed

==================

Cannot stream clone when server.uncompressed is set to false

------------------------------------------------------------

When `server.uncompressed` is disabled, the client should fallback to a bundle

based clone with a warning.

Basic clone

-----------

Check that --stream trigger a stream clone and result in a valid repositoty

We check the associated output for exact bytes on file number as changes in

these value implies changes in the data transfered and can detect unintended

changes in the process.

getbundle requests with stream=1 are uncompressed

-------------------------------------------------

We check that `getbundle` will return a stream bundle when requested.

--uncompressed is an alias to --stream

The alias flag should trigger a stream clone too.

the result should be a valid repository.
