They didn't match the ifdef logic used within libcurl anyway so they
could indeed warn for the wrong case - plus the tool cannot know how the
lib actually performs at that level.

Tests 842, 843, 844, 845, 887, 888, 889, 890, 946, 947, 948 and 949 fail
if a custom port number is specified via the -b option of runtests.pl.

Bug: http://curl.haxx.se/mail/lib-2015-12/0003.html

for all we know now, it might be called 7.46.1

Closes #546

- set the correct stream_id for pushed streams
- init maxdownload and size properly

give the new stream the old one's stream_weight internally to avoid
sending a PRIORITY frame unless asked for it

Fixes warnings 78c25c85 added.

IoctlSocket() apparently wants a pointer to a long, passed as a char *
in its third parameter. This bug was introduced already back in commit
c5fdeef4 from October 1 2001!

Commit f3bae6ed added the URL index to the password prompt when using
--next. Unfortunately, because the size_t specifier (%zu) is not
supported by all sprintf() implementations we use the curl_off_t format
specifier instead. The display of an incorrect value arises on platforms
where size_t and curl_off_t are of a different size.

The RTSP code path didn't skip adding the if-modified-since for certain
RTSP code paths, even if CURLOPT_TIMECONDITION was set to
CURL_TIMECOND_NONE.

Also, an unknown non-zero CURLOPT_TIMECONDITION value no longer equals
CURL_TIMECOND_IFMODSINCE.

... and add a generic explanation for them instead. Each example file
should contain its own description these days.

Fixes #534
Closes #537

It would previously be skipped if an existing error was returned, but
would lead to a previous value being left there and later used.
CURLINFO_TOTAL_TIME for example.

Still it avoids that final progress update if we reached DONE as the
result of a callback abort to avoid another callback to be called after
an abort-by-callback.

Moved some ideas from "next major" to just ordinary ideas since we can
always add new things while keeping the old without doing a "next
major".
