The autogen script is doing too many things. The tests that are set up
in the git hooks are already tested by GitHub with actions on branch
push. Also they don't work if you install wolfSSL somewhere specific.
All one needs to do is run `autoreconf -ivf` to make the configure
script. This is all autogen does now, with the addition of warnings.
1. Update scp.test to delete the empty test file.
2. In wolfSSHd, when coverting an IP address to a printable
representation, the destination needs to be able to handle IPv6
addresses potentially.
1. Added some command line options to the wolfSFTP client to show how to
use a hardcoded automatic file transfer rather than using the command
shell. On top of that, added a script to get and put some sample files.
It was built into the wolfSFTP client to allow for using all forms of
authentication as well as using the command line password.
2. Update wolfSSH_SFTP_STAT() with clearing the error register if it is WANT_READ.
1. Add enable options for "all" and "distro". all enables all options.
distro enables all and turns on both shared and static library builds.
2. Updated the commit-tests script to perform a check on enable-all as well.
3. Made a few syntactical changes to commit-tests.
