Update to use pwmd's BULK command.
I am not sure you would like to have pwmd support included in fetchmail anymore since the recent commit to add the passwordeval parameter. I think the pwmd support is better because it can fetch other server details in addition to a server password.
Anyway, this merge is for speeding up remote pwmd connections by using pwmd's BULK command to send multiple commands in one go. It requires libpwmd >= 8.3.0 since this version adds helper functions to create the BULK s-expression and to parse the command result.
The reverted commit is kinda strange. I must have merged the wrong branch at one time on accident. It is in sync with upstream now with that commit reverted.
Thanks for fetchmail. I use it idle'y. :)
