External Public-Key Authentication API (#72) * Implemented dynamic loading of an external plug-in shared library to delegate public key authentication * Moved conditional compilation of the plugin infrastructure into the configure.ac script to be able to add -ldl to dropbear build only when the flag is enabled * Added tags file to the ignore list * Updated API to have the constructor to return function pointers in the pliugin instance. Added support for passing user name to the checkpubkey function. Added options to the session returned by the plugin and have dropbear to parse and process them * Added -rdynamic to the linker flags when EPKA is enabled * Changed the API to pass a previously created session to the checkPubKey function (created during preauth) * Added documentation to the API * Added parameter addrstring to plugin creation function * Modified the API to retrieve the auth options. Instead of having them as field of the EPKASession struct, they are stored internally (plugin-dependent) in the plugin/session and retrieved through a pointer to a function (in the session) * Changed option string to be a simple char * instead of unsigned char *

Dropbear for Debian
-------------------

This package will attempt to setup the Dropbear ssh server to listen on
port 22.  If the OpenSSH server package ("openssh-server") is installed,
the file /etc/default/dropbear will be set up so that the server does not
start by default.

You can run Dropbear concurrently with OpenSSH 'sshd' by modifying
/etc/default/dropbear so that "NO_START" is set to "0", and changing the
port number that Dropbear runs on.  Follow the instructions in the file.

This package suggests you install the "openssh-client" package, which
provides the "ssh" client program, as well as the "/usr/bin/scp" binary
you will need to be able to retrieve files via SCP from a server running
Dropbear.
