http: pass correct header size to debug callback for chunked post
... when the chunked framing was added, the size of the "body part" of

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.

http_proxy: do not crash with HTTPS_PROXY and NO_PROXY set
... in case NO_PROXY takes an effect

Without this patch, the following command crashes:

    $ GIT_CURL_VERBOSE=1 NO_PROXY=github.com HTTPS_PROXY=https://example.com \
        git clone https://github.com/curl/curl.git

Minimal libcurl-based reproducer:

    #include <curl/curl.h>

    int main() {
      CURL *curl = curl_easy_init();
      if(curl) {
        CURLcode ret;
        curl_easy_setopt(curl, CURLOPT_URL, "https://github.com/");
        curl_easy_setopt(curl, CURLOPT_PROXY, "example.com");
        /* set the proxy type */
        curl_easy_setopt(curl, CURLOPT_PROXYTYPE, CURLPROXY_HTTPS);
        curl_easy_setopt(curl, CURLOPT_NOPROXY, "github.com");
        curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
        ret = curl_easy_perform(curl);
        curl_easy_cleanup(curl);
        return ret;
      }
      return -1;

Curl_pgrsTime - return new time to avoid timeout integer overflow
Setting a timeout to INT_MAX could cause an immediate error to get
returned as timeout because of an overflow when different values of
'now' were used.

This is primarily fixed by having Curl_pgrsTime() return the "now" when
TIMER_STARTSINGLE is set so that the parent function will continue using
that time.
