The handle_options() function advances the base of the argument array and
returns the number of arguments it used. The caller in handle_alias()
wants to reallocate the argv array it passes to this function, and
attempts to do so by subtracting the returned value to compensate for the
change handle_options() makes to the new_argv.
But handle_options() did not correctly count when "-c <config=value>" is
given, causing a wrong pointer to be passed to realloc().
Fix it by saving the original argv at the beginning of handle_options(),
and return the difference between the final value of argv, which will
relieve the places that move the array pointer from the additional burden
of keeping track of "handled" counter.

Previously we parsed GIT_CONFIG_PARAMETERS lazily into a
linked list, and then checked that list during future
invocations of git_config. However, that ignores the fact
that the environment variable could change during our run
(e.g., because we parse more "-c" as part of an alias).
Instead, let's just re-parse the environment variable each
time. It's generally not very big, and it's no more work
than parsing the config files, anyway.
As a bonus, we can ditch all of the linked list storage code
entirely, making the code much simpler.
The test unfortunately still does not pass because of an
unrelated bug in handle_options.

The config_parameters list in config.c is an implementation
detail of git_config_from_parameters; instead, that function
should tell us whether it found anything.

Nobody outside of git_config_from_parameters should need
to use the GIT_CONFIG_PARAMETERS parsing functions, so let's
make them private.

This version of git_config() will be used during repository setup.
As a repository is being set up, $GIT_DIR is not nailed down yet,
git_pathdup() should not be used to get $GIT_DIR/config.

The current behavior is often to print an absolute path rather than
a ../../etc string, but callers must be ready to accept a relative
path, too. The most common output is ".git" (from the toplevel of
an ordinary work tree).
