+ * This parser operates on slices rather than C strings. It performs
+ * slicing and validation only. Operations like turning "%20"→" " or
+ * "80"→80 and perfect hashing can be done later, if needed.
+ *
+ * The Uri object is owned by the caller; it has a lifecycle like the
+ * following:
+ *
+ *    struct Uri uri;
+ *    memset(&uri, 0, sizeof(uri));
+ *
+ *    uriparse(&uri, s1, strlen(s1));
+ *    CHECK_EQ(kUriSchemeHttp, urischeme(uri->scheme, s1));
+ *
+ *    uriparse(&uri, s2, strlen(s2));
+ *    printf("host = %`.*s\n", uri->host.n, s2 + uri->host.i);
+ *
+ * Inner arrays may be granted memory by the caller. The uri->𝐴.i field
+ * is cleared at the mark of this function. No more than uri->𝐴.n items
+ * can be inserted. If we need more than that, then ENOMEM is returned
+ * rather than dynamically extending uri->𝐴.p. However, if uri->𝐴.n==0,
+ * we assume caller doesn't care about uri->𝐴 and its data is discarded.
+ *
+ * @param uri is owned by caller
+ * @param p is caller-owned uri string; won't copy/alias/mutate
+ * @return 0 on success, or -1 w/ errno
+ * @see RFC2396: Uniform Resource Identifiers (URI): Generic Syntax
+ * @see RFC3261: SIP: Session Initiation Protocol
