[rfc] updated epoll man pages ...

[Davide Libenzi]

I updated epoll man pages to reflect the new dual LT/ET behaviour. If you
have feedback about syntax, content and mainly grammatical errors ;)
please let me know before I post to the man pages repository :

http://www.xmailserver.org/linux-patches/epoll.txt
http://www.xmailserver.org/linux-patches/epoll_create.txt
http://www.xmailserver.org/linux-patches/epoll_ctl.txt
http://www.xmailserver.org/linux-patches/epoll_wait.txt

For the ones that want to go wild in editing, I can also give man source
files :

http://www.xmailserver.org/linux-patches/epoll.4
http://www.xmailserver.org/linux-patches/epoll_create.2
http://www.xmailserver.org/linux-patches/epoll_ctl.2
http://www.xmailserver.org/linux-patches/epoll_wait.2
