This will let the compiler catch a problem like:
/* oops, we forgot the NULL */
check_strvec(&vec, "foo");
rather than triggering undefined behavior at runtime.

Our check_strvec_loc() helper uses a variable argument list. When we
va_start(), we must be sure to va_end() before leaving the function.
This is required by the standard (though the effect of forgetting will
vary between platforms).

Add two functions that allow to replace and remove strings contained in
the strvec. This will be used by a subsequent commit that refactors
git-mv(1).
While at it, add a bunch of unit tests that cover both old and new
functionality.
