commands: use keyword arguments in update function This will help us in having a dictionary with the values of all the arguments and we can add more flags without adding an argument to the function. Differential Revision: https://phab.mercurial-scm.org/D2896

rebase: pass "inmemory" directly to _definedestmap() We no longer reassign rbsrt.inmemory in _definedestmap(), so we don't need to pass the whole rebase runtime instance anymore, thus making it clear that it won't be updated. Differential Revision: https://phab.mercurial-scm.org/D2905

hgweb: explain instabilities of unstable changesets (the rest of the themes)

Use ``templater.generate(t, mapping)`` instead of ``templater(t, **pycompat.strkwargs(mapping))``.
