Added noop gettext functions in trunk as discussed on trac-dev.

i18n: don't install _ into builtin namespace, it must be imported explicitly.

TracMercurial: ported r5766 from the 0.11 branch.

TracMercurial: the r5763 fix uncovered a circular dependency problem in hg. This other fix contributed by Gregory Collins works. See also http://www.selenic.com/mercurial/bts/issue605 for further details.

Testing: Merge 5755-5757,5759-5762 from trunk, leaving [5754] for now since it
has a failing unittest.

TracMercurial: ported r5763 from the 0.11 branch.

TracMercurial: improve compatibility with Mercurial versions using `demandimport`.

The `demandimport` mechanism modifies the `__import__` builtin, and this can lead to surprising errors, like with the TH:AccountManager plugin:

{{{
# in mercurial/node.py, with `demandimport` enabled:

import binascii

# in acct_mgr/pwhash.py:

from binascii import hexlify
...
v = long(hexlify(urandom(4)), 16)
# raises => TypeError: 'unloaded module' object is not callable
}}}

It's possibly a bug with demandimport, but even if this gets fixed, we must be compatible with the released Mercurial 0.9.4 (and demandimport is not needed anyway for long running processes).

Thanks to Gregory Collins for reporting the issue.

WorkFlowUpgrade, make migrate_original_to_basic.py script a tad more robust and user-friendly
