Review Comment:
I think `celix_propertiesIterator_next` also should be invoked before `while
(!celix_propertiesIterator_isEnd(&propIter))` . otherwise, a same property is
set in `txtRecord`.
We can resolve it in another way: Only let
`discoveryZeroconfAnnouncer_copyPropertiesToTxtRecord` do
`celix_propertiesIterator_next` whether txtRecord is filled or not.

static bool
discoveryZeroconfAnnouncer_copyPropertiesToTxtRecord(discovery_zeroconf_announcer_t
*announcer, celix_properties_iterator_t *propIter, TXTRecordRef *txtRecord,
uint16_t maxTxtLen, bool splitTxtRecord) {
const char *key;
const char *val;
while (!celix_propertiesIterator_isEnd(propIter)) {
key = propIter->key;
val = propIter->entry.value;
if (key) {
DNSServiceErrorType err = TXTRecordSetValue(txtRecord, key,
strlen(val), val);
if (err != kDNSServiceErr_NoError) {
celix_logHelper_error(announcer->logHelper, "Announcer:
Failed to set txt value, %d.", err);
return false;
}
if (splitTxtRecord && TXTRecordGetLength(txtRecord) >= maxTxtLen
- UINT8_MAX) {
celix_propertiesIterator_next(propIter);
break;
}
}
celix_propertiesIterator_next(propIter);
}
return true;
}
