revlog: add a _datareadfp context manager for data access needs
The helper handles:
1) is there a file handle already open that we shall just reuse,
2) is the revlog inlined or not.
Using a context manager for all read access will help setting up file pointer
caching in later changesets.

Update the existing file to ensure that the dirstate is not in pending state
(where the status of some files in the working copy is not known yet). This in
turn ensures that when the transaction is aborted due to an empty message during
the amend, there should be no rollback.

Issue 3445: amending with --close-branch a commit that created a new head should fail
This shouldn't be possible:
$ hg up -q default
$ hg branch closewithamend
marked working directory as branch closewithamend
$ echo foo > foo
$ hg add foo
$ hg ci -m..
$ hg ci --amend --close-branch -m 'closing'
abort: can only close branch heads
[255]
This silliness fails:
$ hg branch silliness
marked working directory as branch silliness
$ echo b >> b
$ hg ci --close-branch -m'open and close'
abort: can only close branch heads

Setup the repo with a file that gets moved in a second commit.
$ hg init repo
$ cd repo
$ touch a0
$ hg add a0
$ hg commit -m a0
$ hg mv a0 a1
$ hg commit -m a1
$ hg up -q 0
$ hg log -G --template '{rev} {desc}'
o 1 a1
|
@ 0 a0
Now we branch the repro, but re-use the file contents, so we have a divergence
in the file revlog topology and the changelog topology.
$ hg revert --rev 1 --all
removing a0
adding a1
$ hg ci -qm 'a1-amend'
$ hg log -G --template '{rev} {desc}'
@ 2 a1-amend
|
| o 1 a1
|/
o 0 a0
The way mercurial does amends is by folding the working copy and old commit
together into another commit (rev 3). During this process, _findlimit is called
to check how far back to look for the transitive closure of file copy
information, but due to the divergence of the filelog and changelog graph
topologies, before _findlimit was fixed, it returned a rev which was not far
enough back in this case.
$ hg mv a1 a2
$ hg status --copies --rev 0
A a2
a0
R a0
$ hg ci --amend -q
$ hg log -G --template '{rev} {desc}'
@ 3 a1-amend
|
| o 1 a1
|/
o 0 a0
Before the fix, the copy information was lost.
$ hg status --copies --rev 0
A a2
a0
R a0
$ cd ..
Check that amend properly preserve rename from directory rename (issue-4516)
If a parent of the merge renames a full directory, any files added to the old
directory in the other parent will be renamed to the new directory. For some
reason, the rename metadata was when amending such merge. This test ensure we
do not regress. We have a dedicated repo because it needs a setup with renamed
directory)

Test amend with file inclusion options
--------------------------------------
These tests ensure that we are always amending some files that were part of the
pre-amend commit. We want to test that the remaining files in the pre-amend
commit were not changed in the amended commit. We do so by performing a diff of
the amended commit against its parent commit.
