We now provide the "real" names in the CINIT() macro setup for CURLOPT_*
symbols, and we provide backwards compatibility defines for the old
symbols as defines instead of vice versa.

This allows us to better use the CINIT() list to check for existing and
current option names.

with a bonus first rough 'mancheck' target to see which man pages that
are still missing

First explain the data then describe what the callback should return.

Inludes all the sections to consider.

This caused segfaults on tests 823 869 907.

The static connection counter caused a race condition. Moving the
connection id counter into conncache solves it, as well as simplifying
the related logic.

This regression was introduced when *init was split into *init and
*setup...

They were added because of an older code path that used allocations and
should not have been left in the code. With this change the logic goes
back to how it was.

Curl_rand() will return a dummy and repatable random value for this
case. Makes it possible to write test cases that verify output.

Also, fake timestamp with CURL_FORCETIME set.

Only when built debug enabled of course.

Curl_ssl_random() was not used anymore so it has been
removed. Curl_rand() is enough.

create_digest_md5_message: generate base64 instead of hex string

curl_sasl: also fix memory leaks in some OOM situations

Added required "debug" feature, missed in commit 1c9aaa0b, as NTLMv2
calls Curl_rand() which can only be fixed to a specific entropy in
debug builds.

httpproxycode is not reset in Curl_initinfo, so a 407 is not reset even
if curl_easy_reset is called between transfers.

The method change is forbidden by the obsolete RFC2616, but libcurl did
it anyway for compatibility reasons. The new RFC7231 allows this
behaviour so there's no need for the scary "Violate RFC 2616/10.3.x"
notice. Also update the comments accordingly.
