3f5f96ac91 event/ServerSocket: fix get_remote_uid() error value 
Must return -1 on error, not 0.  0 is root.

f06fe1ea98 event/TimeoutMonitor: really reset "active" flag before invoking OnTimeout() 
The previous commit was broken.  D'oh!

d16fb79708 event/TimeoutMonitor: reset "active" flag before invoking OnTimeout() 
The IsActive() method returned true even if the timer was not active,
after it completed once.  This broke the state file timer, and the
state file was not saved periodically.

c3f111a56c event/BufferedSocket: fix inversed buffer check 
This was broken by commit 84d20d9e, which deleted the "!" from the
check.

0efb67b51e DeferredMonitor: fix race condition when using GLib event loop 
Turns out the lock-free code using atomics was not thread-safe.  The
given callback could be invoked by GLib before the source_id attribute
was assigned.  This commit changes the DeferredMonitor class to use a
Mutex to block the event loop until source_id is assigned.  This bug
does not exist in the 0.19 branch because it does not use the GLib
main loop anymore.

422b8472fe event/FullyBufferedSocket: try to write without extra roundtrip 
Postpone the write using IdleMonitor instead of scheduling a write
event.  This reduces the number of system calls, because we don't need
to register and unregister the write event in epoll.
