Fix a bitwise negation assignment issue spotted by Sun Studio

Change direct and indirect assignments of the bitwise negation of 0 to
uint32_t variables to have a "U" suffix. I.e. ~0U instead of ~0. This
eliminates warnings under Sun Studio 12 Update 1:

    "vcs-svn/string_pool.c", line 11: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
    "vcs-svn/string_pool.c", line 81: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
    "vcs-svn/repo_tree.c", line 112: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
    "vcs-svn/repo_tree.c", line 112: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)
    "test-treap.c", line 34: warning: initializer will be sign-extended: -1 (E_INIT_SIGN_EXTEND)

The semantics are still the same as demonstrated by this program:

    $ cat test.c && make test && ./test
    #include <stdio.h>
    #include <stdint.h>

    int main(void)
    {
        uint32_t foo = ~0;
        uint32_t bar = ~0U;

        printf("foo = <%u> bar = <%u>\n", foo, bar);

        return 0;
    }
    cc     test.c   -o test
    "test.c", line 5: warning: initializer will be sign-extended: -1
    foo = <4294967295> bar = <4294967295>
