The git_config_string() interface is very prone to leaking; it
overwrites the contents of the pointer without freeing any existing
value, so:
const char *foo;
...
if (!strcmp(var, "foo.bar"))
git_config_string(&foo, var, value);
is always going to leak if we see the "foo.bar" config more than once.
We don't tend to notice in practice because people don't have a lot of
redundant config, but basically every use of git_config_string() has
this problem.
For simple cases where the initial value of the "foo" pointer is NULL
(like the one above), we can easily convert them to use a variant of the
helper that frees the existing value before writing over it. That works
because free(NULL) is a noop. What we can't change, though, is cases
where the pointer is initialized to a string literal, like:
const char *foo = "some string literal";
In that case it would be incorrect to free() the original value. Those
cases will take more refactoring to make them leak-free, and this patch
punts on that for now.
In each case we switch the underlying variable from "const char *" to
"char *" to indicate that it will always point to allocated memory (and
our git_config_string_dup() interface enforces this).
