Add note for pull request #156

Give names to SimpleSocketServer and SocketNode threads

Add notes for LOGBACK-926 and LOGBACK-904

Fix some typos in manual

Cleanup HTML syntax issues in manual (e.g., extraneous tags)

Update SyslogAppenderTest to explicitly set maximum syslog message size (for test stability)

LOGBACK-926 Update SyslogAppender to set the maxMessageSize to be the system default UDP size to prevent logs from being dropped if they are too large.

LOGBACK-904 Fix typo/mistype in javadoc for TurboFilter

"<includes>" should've been "<include>"

We were null-checking the current status manager instead of the one
passed in.

LOGBACK-350 Prevent SocketNode constructor blocking due to lack of data from client

This prevents a NullPointerException from being thrown, and allows the
socketNodeClosing method to be called for the SocketNode.

Fix for LOGBACK-760.

The constructor creates an ObjectInputStream, and this blocks until the stream
header is received from the client.

If the client doesn't send a stream header, construction of the SocketNode will
hang, preventing SimpleSocketServer from accepting new clients.

This change moves the construction of the ObjectInputStream into
SocketNode.run. As SimpleSocketServer runs this method in a new thread, a rogue
client won't prevent subsequent ones being able to connect.

Fixed issue "Failed to instantiate LoggerContext" because of " java.lang.SecurityException: AccessController.checkPermission is unsupported." (LOGBACK-760) using the solution provided in the comment by ori.

amendment for LOGBACK-644: suppress errors for nonexistent resource includes

Support for elapsed time to jetty and tomcat access logs

* changed direct access of timestamp field to use getTimstamp() instead inside of calculateElapsedTime.

Truncates multi-line subjects to the first line to prevent an SMTP error.

fixes #147

detachLoggerContext removes LoggerContext from ContextSelector. BUT
context.getLogger will create it again. So it's much more proper to
log at first and detach context after that.

fixes #51

Fix for LOGBACK-754

A NullPointerException occurred when setting a JUL logger's level to
null, which should have reset the logger level to the parent's effective
level. The null level was incorrectly propagated to context listeners,
leading to the NPE.

This patch propagates the logger's parent effective level.

Support suppressed exceptions

Check already exists inside called method
