filter-branch: deal with object name vs. pathname ambiguity in tree-filter
'git filter-branch' fails complaining about an ambiguous argument, if
a tree-filter renames a path and the new pathname happens to match an
existing object name.
After the tree-filter has been applied, 'git filter-branch' looks for
changed paths by running:
If the CA path isn't found it's most likely to indicate a
misconfiguration, in which case accepting any certificate is unlikely to
be the correct thing to do.

Commit 1b0d400 refactored the prepare_final() function so
that it could be reused in multiple places. Originally, the
loop had two outputs: a commit to stuff into sb->final, and
the name of the commit from the rev->pending array.
After the refactor, that loop is put in its own function
with a single return value: the object_array_entry from the
rev->pending array. This contains both the name and the object,
but with one important difference: the object is the
_original_ object found by the revision parser, not the
dereferenced commit. If one feeds a tag to "git blame", we
end up casting the tag object to a "struct commit", which
causes a segfault.
Instead, let's return the commit (properly casted) directly
from the function, and take the "name" as an optional
out-parameter. This does the right thing, and actually
simplifies the callers, who no longer need to cast or
dereference the object_array_entry themselves.
When "p4 submit" command fails in P4Submit.applyCommit, the
workspace is left with the changes. We already have code to revert
the changes to the workspace when the user decides to cancel
submission by aborting the editor that edits the change description,
and we should treat the "p4 submit" failure the same way.
Clean the workspace if p4_write_pipe raised SystemExit, so that the
user don't have to do it themselves.

bash prompt: indicate dirty index even on orphan branches
__git_ps1() doesn't indicate dirty index while on an orphan branch.
To check the dirtiness of the index, __git_ps1() runs 'git diff-index
--cached ... HEAD', which doesn't work on an orphan branch,
because HEAD doesn't point to a valid commit.
Run 'git diff ... --cached' instead, as it does the right thing both
on valid and invalid HEAD, i.e. compares the index to the existing
HEAD in the former case and to the empty tree in the latter. This
fixes the two failing tests added in the first commit of this series.
The dirtiness of the worktree is already checked with 'git diff' and
is displayed correctly even on an orphan branch.

bash prompt: test dirty index and worktree while on an orphan branch
There is only a single test exercising the dirty state indicator on an
orphan branch, and in that test neither the index nor the worktree are
dirty.
Add two failing tests to check the dirty state indicator while either
the index is dirty or while both the index and the worktree are dirty
on an orphan branch, and to show that the dirtiness of the index is
not displayed in these cases (the fourth combination, i.e. clean index
and dirty worktree are impossible on an orphan branch). Update the
existing dirty state indicator on clean orphan branch test to match
the style of the two new tests, most importantly to use 'git checkout
--orphan' instead of cd-ing into a repository that just happens to be

refs: split filesystem-based refs code into a new file
As another step in the move to pluggable reference backends, move the
code that is specific to the filesystem-based reference backend (i.e.,
the current system of storing references as loose and packed files) into
a separate file, refs/files-backend.c.
Aside from a tiny bit of file header boilerplate, this commit only moves
a subset of the code verbatim from refs.c to the new file, as can easily
be verified using patience diff:
There are a number of constants, structs, and static functions defined
in refs.c and treated as private to the references module. But we want
to support multiple reference backends within the reference module,
and those backends will need access to some heretofore private
declarations.
We don't want those declarations to be visible to non-refs code, so we
don't want to move them to refs.h. Instead, add a new header file,
refs/refs-internal.h, that is intended to be included only from within
the refs module. Make some functions non-static and move some
declarations (and their corresponding docstrings) from refs.c to this
file.
In a moment we will add more content to the "refs" subdirectory.

Commit f8117f55 ("http: use off_t to store partial file size",
02-11-2015) changed the type of some variables from long to off_t.
Unfortunately, the off_t type is not portable and can be represented
by several different actual types (even multiple types on the same
platform). This makes it difficult to print an off_t variable in
a platform independent way. As a result, this commit causes gcc to
issue some printf format warnings on a couple of different platforms.
In order to suppress the warnings, change the format specifier to use
the PRIuMAX macro and cast the off_t argument to uintmax_t. (See also
the http_opt_request_remainder() function, which uses the same
solution).

This is due to using a single hash to store the list of empty

that hash using grep+delete.
Storing directories in a hash of hashes improves the performance
of this purge step and removes a potentially lengthy delay after
every rebase/mkdirs command.
The svn repository with this behaviour has 110K commits with
unhandled.log containing 170K empty_dir directives.
This takes 10 minutes to process when using a single hash, vs

This arrangement however makes it hard to tweak behaviour of the
underlying implementation without fully replacing. If we want to
introduce a tweaked_SHA1_Update() wrapper to implement the "Update"
in a slightly different way, for example, the implementation of the
wrapper still would want to call into the underlying implementation,
but tweaked_SHA1_Update() cannot call git_SHA1_Update() to get to
the underlying implementation (often but not always SHA1_Update()).
Add another level of indirection that maps platform_SHA1_Update()
and friends to their underlying implementations, and by default make
git_SHA1_Update() and friends map to platform_SHA1_* functions.
Doing it this way will later allow us to map git_SHA1_Update() to
tweaked_SHA1_Update(), and the latter can use platform_SHA1_Update()
in its implementation.
