Viktor Szakats b889b39945 docs: convert man page sources to "curldown" format
To render in Git webviews as-is, to make it easier to edit, verify,
and to sync up with curl.

- add options to not build the `.3` man pages:
  - autotools: `--disable-docs`
  - cmake: `LIBSSH2_BUILD_DOCS=OFF`
- building `.3` man pages requires Perl after this patch.
- drop `mansyntax` and the shell / `grep` / GNU `man` tool requirements with it.
- scripts and most logic were copied from curl.
- add `cd2nroff` from curl, with edits to relax curl-specific checks.
- used `nroff2cd` (from curl) to convert from `.3` to `.md`. Then
  manually fixed copyrights, inline function references and a couple
  of other things.

NAME

libssh2_session_disconnect_ex - terminate transport layer

SYNOPSIS

#include <libssh2.h>

int
libssh2_session_disconnect_ex(LIBSSH2_SESSION *session, int reason,
                              const char *description,
                              const char *lang);

int
libssh2_session_disconnect(LIBSSH2_SESSION *session,
                           const char *description);

DESCRIPTION

session - Session instance as returned by libssh2_session_init_ex(3)

reason - One of the Disconnect Reason constants.

description - Human readable reason for disconnection.

lang - Localization string describing the language/encoding of the description provided.

Send a disconnect message to the remote host associated with session, along with a reason symbol and a verbose description.

As a convenience, the macro libssh2_session_disconnect(3) is provided. It calls libssh2_session_disconnect_ex(3) with reason set to SSH_DISCONNECT_BY_APPLICATION and lang set to an empty string.

RETURN VALUE

Return 0 on success or negative on failure. It returns LIBSSH2_ERROR_EAGAIN when it would otherwise block. While LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
