[Monotone-devel] Update - .migration now does revisions in _MTN, configure overhaul on mainline

[Zack Weinberg]

I just pushed out a whole bunch of work which folks may find interesting.

On nvm.workspace-merge.migration, I've reimplemented the changes I had
on .api a while back, where there's now a full revision stored in the
bookkeeping directory.  Nathaniel was right - the migration
infrastructure did make this a lot simpler.  Note that while it
compiles, it fails the testsuite disastrously.  I may or may not have
time to look at that tomorrow.

On mainline, and I hope I didn't jump the gun putting it there, is a
major overhaul of the configure script.  I tried very hard not to
change what was actually being *tested*, only organization and
structure.  Almost all tests now have their own macros in m4/, so it
is very easy to read through configure.ac and get a overview.  I also
reordered things into a more logical sequence, and removed a number of
duplicate tests.  I'd like to start a conversation on tests that we
don't need to do, but I don't have time to write that message now, so
it can wait.  Please let me know if I broke anything.
