urlapi: don't accept blank port number field without scheme
... as it makes the URL parser accept "very-long-hostname://" as a valid
host name and we don't want that. The parser now only accepts a blank
(no digits) after the colon if the URL starts with a scheme.

ftp: retry getpeername for FTP with TCP_FASTOPEN
In the case of TFO, the remote host name is not resolved at the
connetion time.

For FTP that has lead to missing hostname for the secondary connection.
Therefore the name resolution is done at the time, when FTP requires it.

vquic/ngtcp2.h: define local_addr as sockaddr_storage
This field needs to be wide enough to hold sockaddr_in6 when
connecting via IPv6.  Otherwise, ngtcp2_conn_read_pkt will drop the
packets because of the address mismatch:

strerror: Revert to local codepage for Windows error string
- Change get_winapi_error() to return the error string in the local
  codepage instead of UTF-8 encoding.

Two weeks ago bed5f84 fixed get_winapi_error() to work on xbox, but it
also changed the error string's encoding from local codepage to UTF-8.

We return the local codepage version of the error string because if it
is output to the user's terminal it will likely be with functions which
expect the local codepage (eg fprintf, failf, infof).

This is essentially a partial revert of bed5f84. The support for xbox
remains but the error string is reverted back to local codepage.

ftp: a 550 response to SIZE returns CURLE_REMOTE_FILE_NOT_FOUND
This is primarily interesting for cases where CURLOPT_NOBODY is set as
previously curl would not return an error for this case.

MDTM getting 550 now also returns this error (it returned
CURLE_FTP_COULDNT_RETR_FILE before) in order to unify return codes for
missing files across protocols and specific FTP commands.

libcurl already returns error on a 550 as a MDTM response (when
CURLOPT_FILETIME is set). If CURLOPT_NOBODY is not set, an error would
happen subsequently anyway since the RETR command would fail.

Add test 1913 and 1914 to verify. Updated several tests accordingly due
to the updated SIZE behavior.

imap: set cselect_bits to CURL_CSELECT_IN initially
... when continuing a transfer from a FETCH response.

When the size of the file was small enough that the entirety of the
transfer happens in a single go and schannel buffers holds the entire
data. However, it wasn't completely read in Curl_pp_readresp since a
line break was found before that could happen. So, by the time we are in
imap_state_fetch_resp - there's data in buffers that needs to be read
via Curl_read but nothing to read from the socket. After we setup a
transfer (Curl_setup_transfer), curl just waits on the socket state to
change - which doesn't happen since no new data ever comes.

http: consolidate nghttp2_session_mem_recv() call paths
Previously there were several locations that called
nghttp2_session_mem_recv and handled responses slightly differently.
Those have been converted to call the existing
h2_process_pending_input() function.

Moved the end-of-session check to h2_process_pending_input() since the
only place the end-of-session state can change is after nghttp2
processes additional input frames.

This will likely fix the fuzzing error. While I don't have a root cause
the out-of-bounds read seems like a use after free, so moving the
nghttp2_session_check_request_allowed() call to a location with a
guaranteed nghttp2 session seems reasonable.

Also updated a few nghttp2 callsites to include error messages and added
a few additional error checks.

multi: expand pre-check for socket readiness
Check readiness of all sockets before waiting on them
to avoid locking in case the one-time event FD_WRITE
was already consumed by a previous wait operation.

multi: implement wait using winsock events
This avoids using a pair of TCP ports to provide wakeup functionality
for every multi instance on Windows, where socketpair() is emulated
using a TCP socket on loopback which could in turn lead to socket
resource exhaustion.

A previous version of this patch failed to account for how in WinSock,
FD_WRITE is set only once when writing becomes possible and not again
until after a send has failed due to the buffer filling. This contrasts
to how FD_READ and FD_OOB continue to be set until the conditions they
refer to no longer apply. This meant that if a user wrote some data to
a socket, but not enough data to completely fill its send buffer, then
waited on that socket to become writable, we'd erroneously stall until
their configured timeout rather than returning immediately.

This version of the patch addresses that issue by checking each socket
we're waiting on to become writable with select() before the wait, and
zeroing the timeout if it's already writable.

select: reduce duplication of Curl_poll in Curl_socket_check
Change Curl_socket_check to use select-fallback in Curl_poll
instead of implementing it in Curl_socket_check and Curl_poll.

select: fix poll-based check not detecting connect failure
This commit changes Curl_socket_check to use POLLPRI to
check for connect failure on the write socket, because
POLLPRI maps to fds_err. This is in line with select(2).

The select-based socket check correctly checks for connect
failures by adding the write socket also to fds_err.

The poll-based implementation (which internally can itself
fallback to select again) did not previously check for
connect failure by using POLLPRI with the write socket.

See the follow up commit to this for more information.

This commit makes sure connect failures can be detected
and handled if HAVE_POLL_FINE is defined, eg. on msys2-devel.
