Commit adds SELinux support to dropbear by:
adding a new '--enable-selinux' option to configure; by default, it
is disabled. This option defines an ENABLE_SELINUX preprocessor
macro.
mapping the unix username to the SELinux user which is stored in a
new 'user_sid' attribute in the AuthState object
relabeling the controlling pty
setting the context for the next execve() call to the user_sid
Operations above will not be done when SELinux is disabled. Failures will
generate LOG_ERR messages and in enforcing SELinux mode, dropbear_exit()
will be called.
