eol: rename hook into checkheadshook, add checkallhook (issue2665)

"hook" is still an alias for "checkheadshook".

13616:e6f93ca9ce86

like the deprecated win32text extension does. This means that you can
disable win32text and enable eol and your filters will still work. You
only need to these filters until you have prepared a ``.hgeol`` file.

The ``win32text.forbid*`` hooks provided by the win32text extension
have been unified into a single hook named ``eol.hook``. The hook will
lookup the expected line endings from the ``.hgeol`` file, which means
you must migrate to a ``.hgeol`` file first before using the hook.

See :hg:`help patterns` for more information about the glob patterns
used.

invalid revisions will be pushed. To forbid them completely, use the
``eol.checkallhook`` hook. These hooks are best used as
``pretxnchangegroup`` hooks.
