Implement RFC 5228, 2.4.2.4 (Encoding Characters Using "encoded-character")

* libmu_sieve/encoded.c: New file.
* libmu_sieve/strexp.c: New file.
* libmu_sieve/Makefile.am: Add new files.
* libmu_sieve/require.c (mu_sieve_require): Understand "encoded-character".
* libmu_sieve/sieve-priv.h (mu_i_sv_interp_t): New typedef.
(mu_i_sv_expand_encoded_char): New proto.
(mu_sieve_require_encoded_character): New proto.
* libmu_sieve/sieve.l (string): Rewrite via line_.* functions.  This
fixes memory leaks on mu_sieve_machine_destroy.
(line_finish): Expand ${} sequences before returning.
(mu_sieve_require_encoded_character): New function.
* sieve/tests/enc-char.at: New file.
* sieve/tests/Makefile.am: Add enc-char.at
* sieve/tests/testsuite.at: Likewise.
