docker: support Fedora 21

rpm: make Python 2.7.9 the default Python to include in rpms for EL 5 Use the new and more TLS support in Python 2.7.9.

contrib: make Python 2.7.9 the default in Makefile.python We should utilize (and test) the big API changes and new TLS functionality in Python 2.7.9 whenever possible.

localrepo: remove all external users of localrepo.wopener This change touches every module in which repository.wopener was being used, and changes it for the equivalent repository.wvfs. It should now be possible to remove localrepo.wopener.

localrepo: remove all external users of localrepo.sopener This change touches every module in which repository.sopener was being used, and changes it for the equivalent repository.svfs. It should now be possible to remove localrepo.sopener.

localrepo: remove all external users of localrepo.opener This change touches every module in which repository.opener was being used, and changes it for the equivalent repository.vfs. This is meant to make it easier to split the repository.vfs into several separate vfs. It should now be possible to remove localrepo.opener.

log: use namespace logname and colorname Now that we have the machinary to change the log name and the color label used, let's use that. Tests have been updated accordingly.

namespaces: add colorname member to namespace object Previously, there was no way to change the color label used for 'hg log' output. This patch just adds the member to the object, a future patch will change 'hg log' to use this.

namespaces: add logname member to namespace object Previously, there was no way to change the name used for 'hg log' output. This was inconvenient for extensions that want a template name longer than 12 characters (e.g. remotebookmarks) but a different name for 'hg log'. This patch only adds the member to the object, a future patch will update the 'hg log' code.

namespaces: use named args for namespace api This is just a style change but makes adding new arguments more robust for callers.
