Safe to silence warning adding time delta of poll, which can trigger on

warning C4244: '+=' : conversion from 'time_t' to 'long', possible loss

system.h is aimed to replace curlbuild.h at a later point in time when
we feel confident system.h works sufficiently well.
curl/system.h is currently used in parallel with curl/curlbuild.h
curl/system.h determines a data sizes, data types and include file
status based on available preprocessor defines instead of getting
generated at build-time. This, in order to avoid relying on a build-time
generated file that makes it complicated to do 32 and 64 bit bields from
the same installed set of headers.
Test 1541 verifies that system.h comes to the same conclusion that
curlbuild.h offers.

Bug: https://github.com/curl/curl/issues/1225#issuecomment-290340890Closes#1374
'left' is used as time_t but declared as long.
MinGW complains:
error: conversion to 'long int' from 'time_t {aka long long int}' may alter
its value [-Werror=conversion]
Changed the declaration to time_t.
At least under Windows, there is no SIZEOF_LONG, so it evaluates to 0 even
though sizeof(int) == sizeof(long). This should probably have been
CURL_SIZEOF_LONG, but the type of timeout_ms changed from long to time_t
anyway.
This triggered MSVC warning C4668 about implicitly replacing undefined
macros with '0'.

If we use FTPS over CONNECT, the TLS handshake for the FTPS control
connection needs to be initiated in the SENDPROTOCONNECT state, not
the WAITPROXYCONNECT state. Otherwise, if the TLS handshake completed
without blocking, the information about the completed TLS handshake
would be saved to a wrong flag. Consequently, the TLS handshake would
be initiated in the SENDPROTOCONNECT state once again on the same
connection, resulting in a failure of the TLS handshake. I was able to
observe the failure with the NSS backend if curl ran through valgrind.
Note that this commit partially reverts curl-7_21_6-52-ge34131d.
When receiving chunked encoded data with trailers, and the write
callback returns PAUSE, there might be both body and header to store to
resend on unpause. Previously libcurl returned error for that case.
Added test case 1540 to verify.

Fixes#1354Closes#1357
When using basic-auth, connections and proxy connections
can be re-used with different Authorization headers since
it does not authenticate the connection (like NTLM does).
For instance, the below command should re-use the proxy
connection, but it currently doesn't:
curl -v -U alice:a -x http://localhost:8181http://localhost/
--next -U bob:b -x http://localhost:8181http://localhost/
This is a regression since refactoring of ConnectionExists()
as part of: cb4e2be7c6
Fix the above by removing the username and password compare
when re-using proxy connection at proxy_info_matches().
However, this fix brings back another bug would make curl
to re-print the old proxy-authorization header of previous
proxy basic-auth connection because it wasn't cleared.
For instance, in the below command the second request should
fail if the proxy requires authentication, but would succeed
after the above fix (and before aforementioned commit):
curl -v -U alice:a -x http://localhost:8181http://localhost/
--next -x http://localhost:8181http://localhost/
Fix this by clearing conn->allocptr.proxyuserpwd after use
unconditionally, same as we do for conn->allocptr.userpwd.
Also fix test 540 to not expect digest auth header to be
resent when connection is reused.

- If SSL_get_error is called but no extended error detail is available
then show that SSL_ERROR_* as a string.
Prior to this change there was some inconsistency in that case: the
SSL_ERROR_* code may or may not have been shown, or may have been shown
as unknown even if it was known.

- Add new option CURLOPT_SUPPRESS_CONNECT_HEADERS to allow suppressing
proxy CONNECT response headers from the user callback functions
CURLOPT_HEADERFUNCTION and CURLOPT_WRITEFUNCTION.
- Add new tool option --suppress-connect-headers to expose
CURLOPT_SUPPRESS_CONNECT_HEADERS and allow suppressing proxy CONNECT
response headers from --dump-header and --include.

A client MUST ignore any Content-Length or Transfer-Encoding header
fields received in a successful response to CONNECT.
"Successful" described as: 2xx (Successful). RFC 7231 4.3.6
Prior to this change such a case would cause an error.
In some ways this bug appears to be a regression since c50b878. Prior to
that libcurl may have appeared to function correctly in such cases by
acting on those headers instead of causing an error. But that behavior
was also incorrect.

This flag is meant for the current request based on authentication
state, once the request is done we can clear the flag.
Also change auth.multi to auth.multipass for better readability.

This fixes assertion error which occurs when redirect is done with 0
length body via HTTP/2, and the easy handle is reused, but new
connection is established due to hostname change:
curl: http2.c:1572: ssize_t http2_recv(struct connectdata *,

Assertion `httpc->drain_total >= data->state.drain' failed.
To fix this bug, ensure that http2_handle_stream is called.

... because it causes confusion with users. Example URLs:
"http://[127.0.0.1]:11211:80" which a lot of languages' URL parsers will
parse and claim uses port number 80, while libcurl would use port number
11211.
"http://user@example.com:80@localhost" which by the WHATWG URL spec will
be treated to contain user name 'user@example.com' but according to
RFC3986 is user name 'user' for the host 'example.com' and then port 80
is followed by "@localhost"
Both these formats are now rejected, and verified so in test 1260.

If size_t is 32 bits, MSVC warns:
