The previous commit c57f6281 (mv: let 'git mv file no-such-dir/' error out)
relies on that rename("file", "no-such-dir/") fails if the directory does not
exist (note the trailing slash).  This does not work as expected on Windows:
This rename() call does not fail, but renames "file" to "no-such-dir" (not to
"no-such-dir/file"). Insert an explicit check for this case to force an error.

This changes the error message from

   $ git mv file no-such-dir/
   fatal: renaming 'file' failed: Not a directory

to

   $ git mv file no-such-dir/
   fatal: destination directory does not exist, source=file, destination=no-such-dir/

Since 64a99eb4 git gc refuses to run without the --force option if
another gc process on the same repository is already running.

However, if the repository is shared and user A runs git gc on the
repository and while that gc is still running user B runs git gc on
the same repository the gc process run by user A will not be noticed
and the gc run by user B will go ahead and run.

The problem is that the kill(pid, 0) test fails with an EPERM error
since user B is not allowed to signal processes owned by user A
(unless user B is root).

Update the test to recognize an EPERM error as meaning the process
exists and another gc should not be run (unless --force is given).

This reverts commit 31b49d9b.

That commit taught do_askpass to hand ownership of our
buffer back to the caller rather than simply return a
pointer into our internal strbuf.  What it failed to notice,
though, was that our internal strbuf is static, because we
are trying to emulate the getpass() interface.

By handing off ownership, we created a memory leak that
cannot be solved. Sometimes git_prompt returns a static
buffer from getpass() (or our smarter git_terminal_prompt
wrapper), and sometimes it returns an allocated string from
do_askpass.

Commit 98e2092b taught cat-file to stream blobs with --batch,
which requires that we look up the object type before
loading it into memory.  As a result, we now print the
object header from information in sha1_object_info, and the
actual contents from the read_sha1_file. We double-check
that the information we printed in the header matches the
content we are about to show.

Later, commit 93d2a607 allowed custom header lines for
--batch, and commit 5b086407 made type lookups optional. As a
result, specifying a header line without the type or size
means that we will not look up those items at all.

This causes our double-checking to erroneously die with an
error; we think the type or size has changed, when in fact
it was simply left at "0".

For the size, we can fix this by only doing the consistency
double-check when we have retrieved the size via
sha1_object_info. In the case that we have not retrieved the
value, that means we also did not print it, so there is
nothing for us to check that we are consistent with.

We could do the same for the type. However, besides our
consistency check, we also care about the type in deciding
whether to stream or not. So instead of handling the case
where we do not know the type, this patch instead makes sure
that we always trigger a type lookup when we are printing,
so that even a format without the type will stream as we
would in the normal case.

We currently individually pass the sha1, type, and size
fields calculated by sha1_object_info. However, if we pass
the whole struct, the called function can make more
intelligent decisions about which fields were actually
filled by sha1_object_info.

This patch takes that first refactoring step, passing the
whole struct, so further patches can make those decisions
with less noise in their diffs. There should be no
functional change to this patch (aside from a minor typo fix
in the error message).

As a side effect, we can rename the local variables in the
function to "type" and "size", since the names are no longer
taken.

When rev-parse looks at whether an argument like "foo..bar" or
"foobar^@" is a difference or parent-shorthand, it internally
munges the arguments so that it can pass the individual rev
arguments to get_sha1(). However, we do not consistently un-munge
the result.

For cases where we do not match (e.g., "doesnotexist..HEAD"), we
would then want to try to treat the argument as a filename.
try_difference gets() this right, and always unmunges in this case.
However, try_parent_shorthand() never unmunges, leading to incorrect
error messages, or even incorrect results:

  $ git rev-parse foobar^@
  foobar
  fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

  $ >foobar
  $ git rev-parse foobar^@
  foobar

For cases where we do match, neither function unmunges. This does
not currently matter, since we are done with the argument. However,
a future patch will do further processing, and this prepares for
it. In addition, it's simply a confusing interface for some cases to
modify the const argument, and others not to.

Rev-parse understands that a "--" may separate revisions and
filenames, and that anything after the "--" is taken as-is.
However, it does not understand that anything before the
token must be a revision (which is the usual rule
implemented by the setup_revisions parser).

Since rev-parse prefers revisions to files when parsing
before the "--", we end up with the correct result (if such
an argument is a revision, we parse it as one, and if it is
not, it is an error either way).  However, we misdiagnose
the errors:

  $ git rev-parse foobar -- >/dev/null
  fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'

  $ >foobar
  $ git rev-parse foobar -- >/dev/null
  fatal: bad flag '--' used after filename

In both cases, we should know that the real error is that
"foobar" is meant to be a revision, but could not be
resolved.

Git used to trim the trailing slash, and make the command equivalent
to 'git mv file no-such-dir', which created the file no-such-dir
(while the trailing slash explicitly stated that it could only be a
directory).

This patch skips the trailing slash removal for the destination
path.  The path with its trailing slash is passed to rename(2),
which errors out with the appropriate message:
