localrepo: read requirements file in makelocalrepository()...

localrepo: read requirements file in makelocalrepository() Previously, scmutil.readrequires() loaded the requirements file and validated its content against what was supported. Requirements translate to repository features and are critical to our plans to dynamically create local repository types. So, we must load them in makelocalrepository() before a repository instance is constructed. This commit moves the reading of the .hg/requires file to makelocalrepository(). Because scmutil.readrequires() was performing I/O and validation, we inlined the validation into localrepository.__init__ and removed scmutil.readrequires(). I plan to remove scmutil.readrequires() in a future commit (we can't do it now because statichttprepo uses it). Differential Revision: https://phab.mercurial-scm.org/D4568
