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
~~~c
#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.
