given a code point cp, writes to c the utf-8 code, outputting the length in bytes, if the length is zero, the code point is invalid This can possibly

handle a unicode codepoint write appropriate values into dest src will advance 6 bytes or 12 bytes dest will advance a variable amount (return via poi

check quickly whether the next 8 chars are made of digits at a glance, it looks better than Mula's http://0x80.pl/articles/swar-digits-validate.html

The below 4 will only return valid results if this->thread() == QThread::currentThread(), and if socket != nullptr

Print the header and set up log_start

Binary search based lower_bound; returns the first element >= `val` (or <= `val` if reverse sorted), or end() if no such element exists. This assumes

we don't have SSE, so let us use a scalar function credit: https://johnnylee-sde.github.io/Fast-numeric-string-to-int/

only sets the failureTs if missing, otherwise does nothing.

The string_to_uint32 is exclusively used to map literal strings to 32-bit values. We use memcpy instead of a pointer cast to avoid undefined behaviors

Call this with the lock held.
