If the default write callback is used and no destination has been set, a
NULL pointer would be passed to fwrite()'s 4th argument.

Closes#1874
Now that the form API is deprecated and not used anymore in curl tool,
a lot of its features left untested. Test 650 attempts to check all these
features not tested elsewhere.
- Prepend srcdir include path instead of append.
Prior to this change it was possible that during the check for the size
of curl_off_t the include path of a user's already installed curl could
come before the include path of the to-be-built curl, resulting in the
system.h of the former being incorrectly included for that check.
Closes https://github.com/curl/curl/pull/1870
`conn->connect_state` is NULL when doing a regular non-CONNECT request
over the proxy and should therefor be considered complete at once.

Another mistake in my manual fixups of the largely mechanical
search-and-replace ("connssl->" -> "BACKEND->"), just like the previous
commit concerning HTTPS proxies (and hence not caught during my
earlier testing).

In d65e6cc4f (vtls: prepare the SSL backends for encapsulated private
data, 2017-06-21), this developer prepared for a separation of the
private data of the SSL backends from the general connection data.
This conversion was partially automated (search-and-replace) and
partially manual (e.g. proxy_ssl's backend data).
Sadly, there was a crucial error in the manual part, where the wrong
handle was used: rather than connecting ssl[sockindex]' BIO to the
proxy_ssl[sockindex]', we reconnected proxy_ssl[sockindex]. The reason
was an incorrect location to paste "BACKEND->"... d'oh.

Ever since 70f1db321 (vtls: encapsulate SSL backend-specific data,
2017-07-28), the code handling HTTPS proxies was broken because the
pointer to the SSL backend data was not swapped between
conn->ssl[sockindex] and conn->proxy_ssl[sockindex] as intended, but
instead set to NULL (causing segmentation faults).

... instead of the prefix-less version since WolfSSL 3.12 now uses an
enum with that name that causes build failures for us.

- The part kind MIMEKIND_FILE and associated code are suppressed.
- Seek data origin offset not used anymore: suppressed.
- MIMEKIND_NAMEDFILE renamed MIMEKIND_FILE; associated fields/functions
renamed accordingly.
- Curl_getformdata() processes stdin via a callback.
Back in 2008, (and commit 3f3d6ebe66) we changed the logic in how we
determine the native type for `curl_off_t`. To really make sure we
didn't break ABI without bumping SONAME, we introduced logic that
attempted to detect that it would use a different size and thus not be
compatible. We also provided a manual switch that allowed users to tell
configure to bump SONAME by force.
Today, we know of no one who ever got a SONAME bump auto-detected and we
don't know of anyone who's using the manual bump feature. The auto-
detection is also no longer working since we introduced defining
curl_off_t in system.h (7.55.0).
Finally, this bumping logic is not present in the cmake build.
Closes#1861
This is an adaptation of 2 of Peter Wu's SSLKEYLOGFILE implementations.
The first one, written for old OpenSSL versions:
https://git.lekensteyn.nl/peter/wireshark-notes/tree/src/sslkeylog.c
The second one, written for BoringSSL and new OpenSSL versions:
https://github.com/curl/curl/pull/1346
Note the first one is GPL licensed but the author gave permission to
waive that license for libcurl.
As of right now this feature is disabled by default, and does not have
a configure option to enable it. To enable this feature define
ENABLE_SSLKEYLOGFILE when building libcurl and set environment
variable SSLKEYLOGFILE to a pathname that will receive the keys.
And in Wireshark change your preferences to point to that key file:

Closes https://github.com/curl/curl/pull/1866
curl_mime_encoder() is operational and documented.
curl tool -F option is extended with ";encoder=".
curl tool --libcurl option generates calls to curl_mime_encoder().
New encoder tests 648 & 649.
Test 1404 extended with an encoder specification.
Up2date versions of OpenSSL maintain the default reasonably secure
without breaking compatibility, so it is better not to override the
default by curl. Suggested at https://bugzilla.redhat.com/1483972Closes#1846
