largefiles: fix output of hg summary (issue3060)

largefiles: fix confusion upon removal of added largefile (issue3176) This patch makes "hg remove" work the same way on largefiles as it does on regular Mercurial files. If you try to remove an added largefile, the removal fails and you are instead prompted to use "hg forget" to undo the add.

largefiles: remove invalid comment (issue3065) This comment is invalid. The hg.update() function will abort in the case of any genuine error, so there is nothing to check. If we have gotten to this point in execution, nothing critical has gone wrong, and if any standins have been updated, we must pull new largefiles.

largefiles: clean up and shorten test output by using the same log format everywhere

largefiles: remove a chunk of commented out code

Remove FSF mailing address from GPL headers The GPLv3 FAQ suggests to upgrade by [...] replace all your existing v2 license notices (usually at the top of each file) with the new recommended text available on the GNU licenses howto. It's more future-proof because it no longer includes the FSF's postal mailing address. This removes the postal address, but leaves the version number at 2+.
