core: Fix chunk header parsing defect.
Remove apr_brigade_flatten(), buffering and duplicated code from
the HTTP_IN filter, parse chunks in a single pass with zero copy.
Limit accepted chunk-size to 2^63-1 and be strict about chunk-ext
authorized characters.

Bring SNI behavior into better conformance with RFC 6066:

- no longer send a warning-level unrecognized_name(112) alert
  when no matching vhost is found (PR 56241)

<not backported to 2.2.x>
- at startup, only issue warnings about IP/port conflicts and name-based
  SSL vhosts when running with an OpenSSL without TLS extension support
  (almost 5 years after SNI was added to 2.2.x, the
  "[...] only work for clients with TLS server name indication support"
  warning feels obsolete)
</not backported to 2.2.x>

Adding sub second timestamps and request end time to mod_log_config.

Add special format tokens to %{...}t. The extended syntax allows the
form: "WHICH:WHAT".

WHICH is either:
- "begin": use the time when the request started
- "end": take "now" as the time
You can omit WHICH, default is "begin".
If you omit WHICH, the separating column is not allowed.

WHAT is either:
- "sec": timestamp in Unix seconds
- "msec": timestamp in Unix milliseconds
- "msec_frac": millisecond fraction of the Unix timestamp,
               3 digits, 0-padded
- "usec": timestamp in Unix microseconds
- "usec_frac": microsecond fraction of the Unix timestamp
               6 digits, 0-padded
- anything different from those tokens: use strftime()
You can omit WHAT, default is the formatted timestamp as
used by the Common Log Format.

The implementation uses a new request_config for mod_log_config
to pass the request end time around between different calls to
log formatters, but the end time is only generated if needed.

This makes data consistent if a log format uses
multiple %{...}T and/or %D.
The end time of a request is only taken once and
the same time is used for each log field.
