Although 2to3 will fix most issues in Python 2 code to make it run under
Python 3, it does not handle the new strict separation between byte
strings and unicode strings. There is one instance in
git_remote_helpers where we are caught by this, which is when reading
refs from "git for-each-ref".
Fix this by operating on the returned string as a byte string rather
than a unicode string. As this method is currently only used internally
by the class this does not affect code anywhere else.
Note that we cannot use byte strings in the source as the 'b' prefix is
not supported before Python 2.7 so in order to maintain compatibility
with the maximum range of Python versions we use an explicit call to
encode().

Basically this is what we want:
== pull ==
testgit transport-helper
* export -> import
# testgit.marks git.marks
== push ==
testgit transport-helper
* import <- export
# testgit.marks git.marks
Each side should be agnostic of the other side. Because testgit.marks
(our helper marks) could be anything, not necessarily a format parsable
by fast-export or fast-import. In this test they happen to be compatible,
because we use those tools, but in the real world it would be something
completely different. For example, they might be mapping marks to
mercurial revisions (certainly not parsable by fast-import/export).
This is what we have:
== pull ==
testgit transport-helper
* export -> import
# testgit.marks git.marks
== push ==
testgit transport-helper
* import <- export
# git.marks testgit.marks
The only reason this is working is that git.marks and testgit.marks are
roughly the same.
This new behavior used to not be possible before due to a bug in
fast-export, but with the bug fixed, it works fine.

If fast-export did not complete successfully the error handling code
itself would error out.
This was broken in commit 23b093ee0 (Brandon Casey, Wed Jun 9 2010,
Remove python 2.5'isms). Revert that commit an introduce our own copy
of check_call in util.py instead.
Tested by changing 'if retcode' to 'if not retcode' temporarily.

The following python 2.5 features were worked around:
* the sha module is used as a fallback when the hashlib module is
not available
* the 'any' built-in method was replaced with a 'for' loop
* a conditional expression was replaced with an 'if' statement
* the subprocess.check_call method was replaced by a call to
subprocess.Popen followed by a call to subprocess.wait with a
check of its return status
These changes allow the python infrastructure to be used with python 2.4
which is distributed with RedHat's RHEL 5, for example.
t5800 was updated to check for python >= 2.4 to reflect these changes.

Currently the remote helper infrastructure is only used by the curl
helper, which does not give a good impression of how remote helpers
can be used to interact with foreign repositories. Since implementing
such a helper is non-trivial it would be good to have at least one
easy-to-follow example demonstrating how to implement a helper that
interacts with a foreign vcs using fast-import/fast-export.
The testgit helper can be used to interact with remote git
repositories by prefixing the url with "testgit::".
