Note that for some reason there is this warning (that also exists with
autotools, added since curl-7_15_1-94-ga718cb05f):

    docs/libcurl/curl_multi_socket_all.3:1: can't open `man3/curl_multi_socket.3': No such file or directory

Additionally, adjust the roffit --mandir option to support creating
links when doing out-of-tree builds.

Ref: https://github.com/curl/curl/pull/1288

Also make Perl mandatory to allow building the docs.

While CMakeLists.txt could probably read the list of manual pages from
Makefile.am, actually putting those in CMakeLists.txt is cleaner so that
is what is done here.

Fixes #1230

For easier sharing with CMake. The contents were reformatted to use
two-space indent and expanded tabs (matching lib/Makefile.common).

The code would refer to the wrong data pointer. Only debug builds do
this - for verbosity.

Fixes #1329

These tests use an HTTP proxy so require that curl be built with HTTP
support.

The CURLOPT_USERAGENT and CURLOPT_MAXREDIRS options are only set if HTTP
support is available, so ignore them in tests where HTTP is not
guaranteed.

Broken a week ago in 6448f98c.

Closes https://github.com/curl/curl/pull/1337

- Show the HTTPS-proxy options on CURLE_SSL_CACERT if libcurl was built
  with HTTPS-proxy support.

Prior to this change those options were shown only if an HTTPS-proxy was
specified by --proxy, but that did not take into account environment
variables such as http_proxy, https_proxy, etc. Follow-up to e1187c42.

Bug: https://curl.haxx.se/mail/lib-2017-03/0017.html

Depend on the known behaviour of URLs for nonexistent files rather than
the undefined behaviour of URLs for directories (which fails on Windows).
The test isn't about file: URLs at all, so the URL used doesn't really
matter.

Otherwise, the contents will end up in the output and fail the
verification.

If a % ended the statement, the string's trailing NUL would be skipped
and memory past the end of the buffer would be accessed and potentially
displayed as part of the --write-out output. Added tests 1440 and 1441
to check for this kind of condition.

- Add new option CURLOPT_SUPPRESS_CONNECT_HEADERS to allow suppressing
  proxy CONNECT response headers from the user callback functions
  CURLOPT_HEADERFUNCTION and CURLOPT_WRITEFUNCTION.

- Add new tool option --suppress-connect-headers to expose
  CURLOPT_SUPPRESS_CONNECT_HEADERS and allow suppressing proxy CONNECT
  response headers from --dump-header and --include.

Closes https://github.com/curl/curl/pull/783

A client MUST ignore any Content-Length or Transfer-Encoding header
fields received in a successful response to CONNECT.
"Successful" described as: 2xx (Successful). RFC 7231 4.3.6

Prior to this change such a case would cause an error.

In some ways this bug appears to be a regression since c50b878c. Prior to
that libcurl may have appeared to function correctly in such cases by
acting on those headers instead of causing an error. But that behavior
was also incorrect.

Do not call curl_easy_reset() between the requests, because the
auth state must be preserved for these tests.

This flag is meant for the current request based on authentication
state, once the request is done we can clear the flag.

Also change auth.multi to auth.multipass for better readability.
