sendmail: support AUTH PLAIN in addition to AUTH LOGIN
Implement the -am argument to allow choosing an AUTH method. For now only PLAIN and LOGIN are supported, but others can be added easily in the future. AUTH PLAIN required adding a new variant of encode_base64() capable of handling NUL characters in the input string; the old function is now a wrapper for the newer one. function old new delta encode_n_base64 - 236 +236 sendmail_main 1199 1380 +181 packed_usage 32873 32877 +4 encode_base64 242 36 -206 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/1 up/down: 421/-206) Total: 215 bytes Signed-off-by: Raffaello D.
