share-safe: add support for static-http repository We need to read the second requirements file in the static-http case too. Otherwise, static-http would miss most of the requirements and misbehave. Differential Revision: https://phab.mercurial-scm.org/D11996

legacy-revlog: fix requirement computation when cloning legacy repo The oldest format of repository does not have requirements so we need to treat them differently when cloning such repository. The previous code had issue whenever we start using a working-copy-only requirements. The "legacy" format is signaled using an empty requirements list. If we add working-copy-only requirements to it, this is no longer empty, and no longer legacy. The new code fix this, and will get fully tested in a couple of changeset, once the share-safe become the default. Differential Revision: https://phab.mercurial-scm.org/D11995

requirements: do not warn about dropping share-safe, unless explicitly set If we are just altering the default value, this is "fine". This will get tested once share-safe become the default. Differential Revision: https://phab.mercurial-scm.org/D11994
