... and use internally. This function will return TIME_T_MAX instead of
failure if the parsed data is found to be larger than what can be
represented. TIME_T_MAX being the largest value curl can represent.

This is a protocol violation but apparently there are legacy proprietary

It was used (intended) to pass in the size of the 'socks' array that is
also passed to these functions, but was rarely actually checked/used and
the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries
that should be used instead.

They serve very little purpose and mostly just add noise. Most of them

Due to limitations in Curl_resolver_wait_resolv(), it doesn't work for

Limitation added to KNOWN_BUGS.

- no need to have them protocol specific
- no need to set pointers to them with the Curl_setup_transfer() call
- make Curl_setup_transfer() operate on a transfer pointer, not
connection
- switch some counters from long to the more proper curl_off_t type
Closes#3627
This allows the compiler to pack and align the structs better in
memory. For a rather feature-complete build on x86_64 Linux, gcc 8.1.2
makes the Curl_easy struct 4.9% smaller. From 6312 bytes to 6000.
Removed an unused struct field.
No functionality changes.
Closes#3610
Instead of using a fixed 256 byte buffer in the connectdata struct.
In my build, this reduces the size of the connectdata struct by 11.8%,
from 2160 to 1904 bytes with no functionality or performance loss.
This also fixes a bug in schannel's Curl_verify_certificate where it
called Curl_sspi_strerror when it should have called Curl_strerror for
string from GetLastError. the only effect would have been no text or the
wrong text being shown for the error.

The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

The result of a memory allocation should always be checked, as we may
run under memory pressure where even a small allocation can fail. This
adds checking and error handling to a few cases where the allocation
wasn't checked for success. In the ftp case, the freeing of the path
variable is moved ahead of the allocation since there is little point
in keeping it around across the strdup, and the separation makes for
more readable code. In nwlib, the lock is aslo freed in the error path.
Also bumps the copyright years on affected files.

In the situation of a client connecting to an FTP server using an IPv6
tunnel proxy, the connection info will indicate that the connection is
IPv6. However, because the server behing the proxy is IPv4, it is
permissable to attempt PSV mode. In the case of the FTP server being
IPv4 only, EPSV will always fail, and with the current logic curl will
be unable to connect to the server, as the IPv6 fwdproxy causes curl to
think that EPSV is impossible.
Closes#2432
Refuse to operate when given path components featuring byte values lower
than 32.
Previously, inserting a %00 sequence early in the directory part when
using the 'singlecwd' ftp method could make curl write a zero byte
outside of the allocated buffer.
