These two files were always tightly connected and it was hard to

By avoiding an unnecessary error check and the temp use of the tm
struct, the time2epoch conversion function gets a little bit faster.
When repeating test 517, the updated version is perhaps 1% faster (on
one particular build on one particular architecture).

If the received PASV response doesn't match the expected pattern, we

Since the struct is quite large (1 long and 10 ints) we
declare it once at the beginning of the function instead
of multiple times inside loops to avoid stack movements.

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.

... 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.
Closes#5961
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.

If the error reason from the lib is
SSL_R_SSLV3_ALERT_CERTIFICATE_EXPIRED, libcurl will return
CURLE_PEER_FAILED_VERIFICATION and not CURLE_SSL_CONNECT_ERROR.
This unifies the libcurl return code and makes libressl run test 313

The cache content is not duplicated, like other caches, but the setting
and specified file name are.
Test 1908 is extended to verify this somewhat. Since the duplicated
handle gets the same file name, the test unfortunately overwrites the
same file twice (with different contents) which makes it hard to check
automatically.
