tests: add some script lint checks
There are some common but minor errors we tend to make in
writing test scripts:
1. Scripts are left non-executable. This is not usually
noticed immediately because "make test" does not need
the bit, but it is a matter of git policy to make them
executable (and is a slight convenience when running
individual scripts).
2. Two scripts are allocated the same number. Usually this
happens on separate branches, and the problem only
comes about during a merge. But since there is no
textual conflict, the merger would have to be very
observant to notice.
This is also a minor error, but can make GIT_SKIP_TESTS
ambiguous.
This patch introduces a "test-lint" target which checks
both. It is not invoked by default. You can invoke it as
"make test-lint", or you can make it a prerequisite of
running the tests by specifying "TEST_LINT = test-lint" in
your config.mak or on the command line.

Apparently a "feature" of Tcl/Tk on Mac OS X is that a disabled text

makes the diff viewer almost useless on that platform as you cannot
select individual parts of the buffer.
Now we force focus into the diff viewer when its clicked on with

update-index: migrate to parse-options API
--refresh and --really-refresh accept flags (like -q) and modify
an error indicator. It might make sense to make the error
indicator global, but just pass the flags and a pointer to the error
indicator in a struct instead.
--cacheinfo wants 3 arguments. Use the OPTION_LOWLEVEL_CALLBACK
extension to grab them and PARSE_OPT_NOARG to disallow the "sticked"
--cacheinfo=foo form. (The resulting message
$ git update-index --cacheinfo=foo
error: option `cacheinfo' takes no value
is unfortunately incorrect.)
--assume-unchanged and --no-assume-unchanged probably should use the
OPT_UYN feature; but use a callback for now so the existing MARK_FLAG
and UNMARK_FLAG values can be used.
--stdin and --index-info are still constrained to be the last argument
(implemented using the OPTION_LOWLEVEL_CALLBACK extension).
--unresolve and --again consume all arguments that come after them
(also using OPTION_LOWLEVEL_CALLBACK).
The order of options matters. Each path on the command line is
affected only by the options that come before it. A custom
argument-parsing loop with parse_options_step() brings that about.
In exchange for all the fuss, we get the usual perks: support for
un-sticked options, better usage error messages, more useful -h
output, and argument parsing code that should be easier to tweak
in the future.

setup: save prefix (original cwd relative to toplevel) in startup_info
Save the path from the original cwd to the cwd at the end of the
setup procedure in the startup_info struct introduced in e37c1329
(2010-08-05). The value cannot vary from thread to thread anyway,
since the cwd is global.
So now in your builtin command, instead of passing prefix around,
when you want to convert a user-supplied path to a cwd-relative
path, you can use startup_info->prefix directly.
Caveat: As with the return value from setup_git_directory_gently(),
startup_info->prefix would be NULL when the original cwd is not a
subdir of the toplevel.
Longer term, this would allow the prefix to be reused when several
noncooperating functions require access to the same repository (for
example, when accessing configuration before running a builtin).

parse-options: allow git commands to invent new option types
parse-options provides a variety of option behaviors, including
OPTION_CALLBACK, which should take care of just about any sane
behavior. All supported behaviors obey the following constraint:
A --foo option can only accept (and base its behavior on)
one argument, which would be the following command-line
argument in the "unsticked" form.
Alas, some existing git commands have options that do not obey that
constraint. For example, update-index --cacheinfo takes three
arguments, and update-index --resolve takes all later parameters as
arguments.
Introduces an OPTION_LOWLEVEL_CALLBACK backdoor to parse-options so
such option types can be supported without tempting inventors of other
commands through mention in the public API. Commands can set the
callback field to a function accepting three arguments: the option
parsing context, the option itself, and a flag indicating whether the
the option was negated. When the option is encountered, that function
is called to take over from get_value(). The return value should be
zero for success, -1 for usage errors.
