clone: add support for storing remotenames while cloning If `experimental.remotenames` is set to True, we store the remotenames in case of `hg pull`. This patch adds that support to clone command also. Differential Revision: https://phab.mercurial-scm.org/D1601

revset: use phasecache.getrevset to calculate public() Other revsets like secret(), draft(), _nonpublic() are using phasescache.getrevset already. The latter is more efficient after D1606. So let's migrate the public() revset function too. Tested using: $ hg debugshell --hidden --cwd hg-committed` In [1]: %timeit len(repo.revs('public()')) * Before D1606: 10 loops, best of 3: 22.5 ms per loop * Before this change, after D1606: 10 loops, best of 3: 28.6 ms per loop * After this change: 10 loops, best of 3: 20.2 ms per loop Therefore `public()` revset becomes even slightly faster after the data structure change by D1606. A similar performance win could also be observed on a large repo. A side effect is `phasecache.getrevset` needs to take a `subset` parameter. That was added with a default value so it won't cause BC issues. Differential Revision: https://phab.mercurial-scm.org/D1620

highlight: eagerly discover plugin lexers while demandimport is off Since highlight is only relevant for servers, it seems worthwhile to just trigger this eagerly, which avoids really weird traceback problems caused by demandimport messing with some of the lexer plugins.
