- Change documented param type to char ** from incorrect long *.

--without-ssl is needed instead of --with-winssl.

Closes #1382

Closes https://github.com/curl/curl/pull/1375

For some reason, CMake 2.8.12.2 did not expand the list argument in a
single DEPENDS argument. Remove the quotes, so it gets expanded into
multiple arguments for add_custom_command and add_custom_target.

Closes #1372

Closes #1364

Closes #1366

Closes #1356

Send curl_socket_t to event_cb and make sure it hasn't been closed yet.

Ref: https://curl.haxx.se/mail/lib-2017-02/0097.html

Closes https://github.com/curl/curl/pull/1272

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.

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

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

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

... as we no longer use libidn

... previously, docs/ was only a dist subdir, now also a build subdir.

- 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.
