The new --with-crypto option replaces the previous backend-specific
--with-{openssl,libgcrypt,mbedtls,wincng} options and fixes some issues.
* libgcrypt or mbedtls would previously be used whenever found, even
if configure was passed --without-libgcrypt or --without-mbedtls.
* If --with-$backend was specified then configure would not fail even
if that library could not be found, and would instead use whichever
crypto library was found first.
The new option defaults to `auto`, which makes configure check for all
supported crypto libraries in turn, choosing the first one found, or
exiting with an error if none can be found.
channel_wait_eof waits for channel->remote.eof, which is set on
receiving a `SSH_MSG_CHANNEL_EOF` message. This message is sent
when a party has no more data to send on a channel.
Somehow it got Windows-style CRLF endings so convert to just LF,
for consistency as well as not to confuse tools that will regard
the \r as content (e.g. the OpenVMS help librarian).
Net::SSH2, the Perl wrapping module for libssh2 implements several features*
on top of libssh2 that can fail and so need some mechanism to report the error
condition to the user.
Until now, besides the error state maintained internally by libssh2, another
error state was maintained at the Perl level for every session object and then
additional logic was used to merge both error states. That is a maintenance
nighmare, and actually there is no way to do it correctly and consistently.
In order to allow the high level language to add new features to the library
but still rely in its error reporting features the new function
libssh2_session_set_last_error (that just exposses _libssh2_error_flags) is
introduced.
*) For instance, connecting to a remote SSH service giving the hostname and
port.

Despite we announced the CMake support in libssh2-1.6.0 release notes,
the files required by the CMake build system were not included in the
release tarballs. Hence, the only way to use CMake for build was the
upstream git repository.
This commit makes CMake actually supported in the release tarballs.
The new libssh2_sftp_fsync API causes data and metadata in the
currently open file to be committed to disk at the server.
This is an OpenSSH extension to the SFTP protocol. See:
https://bugzilla.mindrot.org/show_bug.cgi?id=1798
Someone on IRC pointed out that we don't have these documented so I
wrote up a first set based on the information in the wiki:
