See MANPAGE.md for the description of how this works. Each command line
option is now described in a separate .d file.

Blah, I accidentally wrote size_t instead of time_t for two variables.

... as long is still 32bit on modern 64bit windows machines, while
time_t is generally 64bit.

This stops the compiler from potentially making invalid assumptions
about the immutability of sdp and sap across the longjmp boundary.

Previously, the [host] part was just ignored which made libcurl accept
strange URLs misleading users. like "file://etc/passwd" which might've
looked like it refers to "/etc/passwd" but is just "/passwd" since the
"etc" is an ignored host name.

1.1.0+ does more of this by itself so we can avoid extra processing this
way.

Now I've managed to negotiate TLS 1.3 with https://enabled.tls13.com/ when
using boringssl.

- Fix GnuTLS code for CURL_SSLVERSION_TLSv1_2 that broke when the
TLS 1.3 support was added in 6ad3add6.

- Homogenize across code for all backends the error message when TLS 1.3
is not available to "<backend>: TLS 1.3 is not yet supported".

- Return an error when a user-specified ssl version is unrecognized.

---

Prior to this change our code for some of the backends used the
'default' label in the switch statement (ie ver unrecognized) for
ssl.version and treated it the same as CURL_SSLVERSION_DEFAULT.

If SPNEGO fails, cleanup the negotiate handle right away.

We're mostly saying just "curl" in lower case these days so here's a big
cleanup to adapt to this reality. A few instances are left as the
project could still formally be considered called cURL.

Previously, we just ignored "Connection" header field.  But HTTP/2
specification actually prohibits few more header fields.  This commit
ignores all of them so that we don't send these bad header fields.

- Call Curl_initinfo on init and duphandle.

Prior to this change the statistical and informational variables were
simply zeroed by calloc on easy init and duphandle. While zero is the
correct default value for almost all info variables, there is one where
it isn't (filetime initializes to -1).
