Testing Curl_llist_insert_next

... to not make the connection between the tool and the libcurl used
tighter than necessary, the tlsauth options are now always present but
if the used libcurl doesn't have TLSAUTH support it will return failure.

Also, replaced strncmp() with strequal to get case insensitive matching.

Test case 1014 failed since TLS-SRP was correctly set to the features
variable so curl-config --features didn't output it.

The default value is 1.

curl _uses_ a default CA bundle, it doesn't install one.

Drop the references to 7.10 as that is now >8 years old!

Extended the intial HTTP protcol part and added a mention of --trace and
--trace-ascii.

Replaced most URLs in the text to use example.com instead of all the
made up strange names.

Shortened a bunch of lines.

Extended the descriptions somewhat and made the options get listed next
to each other.

Submitted by Vincent Torri.

... and update the curl.1 and curl_easy_setopt.3 man pages such that
they do not suggest to use an OpenSSL utility if curl is not built
against OpenSSL.

Get rid of stdout redirection to NUL and move stderr redirection
into RM and RMDIR macros.

Check for BCCDIR environment var done now as other checks.

Borland's $(MAKEDIR) expands to the path where make.exe is located,
use this feature to define BCCDIR when user has not defined BCCDIR.

The idea that the protocol and socktype is part of name resolving in the
libc functions is nuts. We keep the name resolver functions assume
TCP/STREAM and we make sure that when we want to connect to a UDP
service we use the correct UDP/DGRAM set instead. This bug was because
the ->protocol field was not always set correctly.

This bug was only affecting ipv6-disabled non-cares non-threaded builds.

Only under Windows

CMake/CheckTypeSize.c.in and CMake/CheckTypeSize.cmake were removed in
the previous cmake commit

This makes it possible to skip the call to unit_stop() in such
cases.  Also use Curl_safefree() in unit test 1302 so it will
pass the memory torture test.

The just added speedcheck must not ruin the error code if already set
due to a problem.

The CheckTypeSize module that comes with CMake 2.6.2 and above does
everything we need and also supports cross-compiling.  Avoid duplicating
an older version of it here.  This also fixes a cross-compiling error
because the old line

  include ("${CMAKE_MODULE_PATH}/CheckTypeSize.cmake")

failed because CMAKE_MODULE_PATH is a search path and not a directory.
