libei-1.2.0

[Bruce Dubbs]

New minor version.

[Xi Ruoyao]

Notable fixes in this release include better handling of various protocol errors and less log spam:

• if the write buffer is full, outgoing messages are now cached instead of returning EAGAIN.
• if a message send fails, stop trying to send more messages which will do nothing but spam the log with more errors
• if we get disconnected by the server, stop trying to send things to the server (and spam the log on error)
• use EINTR checks instead of blocking SIGALRM
• keep a cache of defunct objects to avoid spamming the log when there are in-flight messages arriving after destroy
