Netty Direct Buffer warning fix

When deploying Wildfly 8.x, you'll see this in the server.log:
```
INFO [io.netty.util.internal.PlatformDependent] Your platform does not provide complete low-level API for accessing direct buffers reliably. Unless explicitly requested, heap buffer will always be preferred to av
oid potential system unstability.
```
Following this into netty, here:
https://github.com/netty/netty/blob/master/common/src/main/java/io/netty/util/internal/PlatformDependent.java#L581
Down to here:
https://github.com/netty/netty/blob/netty-4.0.15.Final/common/src/main/java/io/netty/util/internal/PlatformDependent0.java#L82

We need access to sun.misc to see if direct buffers are available.
Update module.xml

Added javassist after inspecting io.netty log messages as "FINE" level after Wildfly startup and seeing additional information from netty requesting javassist for performance.
Update module.xml

Add optional flag to javassist as this is part of Wildfly-core
Replace ForkChannelService with ForkChannelFactoryService.
Fix javadoc
Replace tabs w/spaces.

WFLY-3934 TimerServiceImpl should use message patterns

When running an allocation profile on our WildFly AS instance debug
logging in `TimerServiceImpl` showed up. The problem is that
`TimerServiceImpl` unconditionally generates debug strings using string
concatenation.

 * use `#debugv` instead of `#debug` for debug messages that take
   arguments to avoid allocating strings in case when debug logging is
   disabled
 * put calls to `#getTimedObjectId` for debug strings in `if` blocks
   since it additionally allocates strings
