context: move contents of committablectx.markcommitted() to workingctx
Same reasoning as previous commits: this function updates the
dirstate. By not updating the dirstate here, we also fix the
close-head test.

A script that implements uppercasing all letters in a file.

Tests for the fix extension's behavior around non-trivial history topologies.
Looks for correct incremental fixing and reproduction of parent/child
relationships. We indicate fixed file content by uppercasing it.

This tests the only behavior that should really be affected by obsolescence, so
we'll test it with evolution off and on. This only changes the revision
numbers, if all is well.
#testcases obsstore-off obsstore-on
#if obsstore-on
$ cat >> $HGRCPATH <<EOF
> [experimental]
> evolution.createmarkers=True
> evolution.allowunstable=True
> EOF
#endif
Setting up the test topology. Scroll down to see the graph produced. We make it
clear which files were modified in each revision. It's enough to test at the
file granularity, because that demonstrates which baserevs were diffed against.
The computation of changed lines is orthogonal and tested separately.

The five revisions remain, but the other revisions were fixed and replaced. All
parent pointers have been accurately set to reproduce the previous topology
(though it is rendered in a slightly different order now).

Change C is a root of the set being fixed, so all we fix is what has changed
since its parent. That parent, change B, is its baserev.
$ hg cat -r $C 'set:**'
aaaa
bbbb
CCCC
Change E is a merge with only one parent being fixed. Its baserevs are the
unfixed parent plus the baserevs of the other parent. This evaluates to changes
B and D. We now have to decide what it means to incrementally fix a merge
commit. We choose to fix anything that has changed versus any baserev. Only the
undisturbed content of the common ancestor, change A, is unfixed.
$ hg cat -r $E 'set:**'
aaaa
BBBB
CCCC
DDDD
EEEE
Change H is a merge with neither parent being fixed. This is essentially
equivalent to the previous case because there is still only one baserev for
each parent of the merge.
$ hg cat -r $H 'set:**'
aaaa
FFFF
GGGG
HHHH
Change I is a merge that has four baserevs; two from each parent. We handle
multiple baserevs in the same way regardless of how many came from each parent.
So, fixing change H will fix any files that were not exactly the same in each
baserev.
$ hg cat -r $I 'set:**'
aaaa
BBBB
CCCC
DDDD
EEEE
FFFF
GGGG
HHHH
IIII
Change J is a simple case with one baserev, but its baserev is not its parent,
change C. Its baserev is its grandparent, change B.
$ hg cat -r $J 'set:**'
aaaa
bbbb
CCCC
JJJJ
The working copy was dirty, so it is treated much like a revision. The baserevs
for the working copy are inherited from its parent, change H, because it is
also being fixed.
$ cat *
aaaa
FFFF
GGGG
HHHH
KKKK
Change A was never a baserev because none of its children were to be fixed.
$ cd ..
The --all flag should fix anything that wouldn't cause a problem if you fixed
it, including the working copy. Obsolete revisions are not fixed because that
could cause divergence. Public revisions would cause an abort because they are
immutable. We can fix orphans because their successors are still just orphans
of the original obsolete parent. When obsolesence is off, we're just fixing and
replacing anything that isn't public.
