When the size of the file was small enough that the entirety of the

imap_state_fetch_resp - there's data in buffers that needs to be read

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.

Well-behaving HTTP2 servers send two GOAWAY messages. The first
message is a warning that indicates that the server is going to
stop accepting streams. The second one actually closes the stream.
nghttp2 reports this state (and the other state of no more stream
identifiers) via the call nghttp2_session_check_request_allowed().
In this state the client should not create more streams on the
session (tcp connection), and in curl this means that the server
has requested that the connection is closed.
It would be also be possible to put the connclose() call into the
on_http2_frame_recv() function that triggers on the GOAWAY message.
This fixes a bug seen when the client sees the following sequence of
frames:
// advisory GOAWAY
HTTP2 GOAWAY [stream-id = 0, promised-stream-id = -1]
... some additional frames
// final GOAWAY
HTTP2 GOAWAY [stream-id = 0, promised-stream-id = N ]
Before this change, curl will attempt to reuse the connection even
after the last stream, will encounter this error:
* Found bundle for host localhost: 0x5595f0a694e0 [can multiplex]
* Re-using existing connection! (#0) with host localhost

To reduce the amount of allocations needed for creating a Curl_addrinfo
struct, make a single larger malloc instead of three separate smaller
ones.
Closes#5533
quiche now requires the application to explicitly set the keylog path
for each connection, rather than reading the environment variable
itself.
Closes#5541
Now that all functions in select.[ch] take timediff_t instead
of the limited int or long, we can remove type conversions
and related preprocessor checks to silence compiler warnings.
Avoiding conversions from time_t was already done in 842f73de.

On some systems, openssl 1.0.x is still the default, but it has been
patched to contain all the recent security fixes. As a result of this
patching, it is possible for macro X509_V_FLAG_NO_ALT_CHAINS to be
defined, while the previous behavior of openssl to not look at trusted
chains first, remains.
Fix it: ensure X509_V_FLAG_TRUSTED_FIRST is always set, do not try to
probe for the behavior of openssl based on the existence ofmacros.
Closes#5530
Commit 4a4b63d forgot to set the expected SOCKS5 reply length when the
reply ATYP is X'01'. This resulted in erroneously expecting more bytes
when the request length is greater than the reply length (e.g., when
remotely resolving the hostname).
Closes#5527
