merge: perform case-collision checking on final set of actions

When there are multiple common ancestors, we should check for case
collisions only on the resulting actions after bid merge has run. To
do this, move the code until after bid merge.

Move it past _resolvetrivial() too, since that might update
actions. If the remote changed a file and then reverted the change,
while the local side deleted the file and created a new file with a
name that case-folds like the old file, we should fail before this
patch but not after.

Although the changes to the actions caused by _forgetremoved() should
have no effect on case collisions, move it after that, too, so the
next person reading the code won't have to think about it.

Moving it past these blocks of code takes it to the end of
calculateupdates(), so let's even move it outside of the method, so we
also check collisions in actions produced by extensions overriding the
method.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See http://mercurial.selenic.com/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
