d9528c265b check_http: Fix memory reallocation error in chunk decoding logic 
This patch should fix an error with the way memory reallocation was
used, which resulted in "realloc(): invalid next size".
It is not completely clear to me as to what caused this problem, but
apparently one can not depend handing a pointer to "realloc(3)" and
expect that it still works afterwards, but one should/must use the one
returned by the function.

Also this patch replaces a variable which was used to remember the
position in the array by just computing that from the current values.

763862a61c make check_http faster with larger files 
The current implementation becomes exponentially slower with growing
response size.

8f54442c68 Added ability to correctly check redirects with reference format //test.server.com/folder 
Referenced redirect of the format //www.server.com/folder would result
in check_http trying to contact http://hostname:80//www.server.com/folder
instead of http://www.server.com/folder. Referenced redirect of this format
is listed in rfc3986 ( https://tools.ietf.org/html/rfc3986 ). It should
work as expected now.

9966ebcd84 Add new flag --show-body/-B to print body 
This should help with figuring out ia problem at a glance when enabled for
healthz endpoints on web APIs, for example.

The content of the body can point to what the problem is and help with
diagnostics.

22c00bbe47 Docs check_http: make -C obvious 
You need to read the docs carefully to realize that check_http has two 
modes of operation: the regular HTTP checks, and a TLS certificate 
check. Only one of these can be run in a single invocation.

fe1c4bb0e5 add openssl 1.1 support 
changes:
  - CRYPTO_lock detection replaced in configure.ac. We don't use that
    function anywhere, so just replace it with the suggested one from
    https://wiki.openssl.org/index.php/Library_Initialization#Autoconf
  - OPENSSL_NO_SSL2 is no longer defined while ssl2 is not included.
    Set it ourself using the suggested openssl 1.1 version check from
    https://wiki.openssl.org/index.php/1.1_API_Changes#Backward_compatibility
  - openssl 1.1 sends a sigpipe if the connection is still open when
    calling SSL_shutdown(), so move the close before the shutdown.
