OPC UA 1.05 April Update

1.05.374 April Release

This release is based on the 1.05.03 Nodeset with generated files from the ModelCompiler.
The focus in this release was on security improvements and bug fixes.

Improvements

• Bug Fixes for the GDS support (@romanett).
• Fix many typos and simplify Xml floating point encoder/decoder (@mtx500).
• More tests for PubSub (@mrsuciu).
• Add timer in the server to clean up stale channels, limit the total number of active channels (@mrsuciu).
• UA Fuzzer framework for afl-fuzz and libfuzzer, fuzz targets for Binary and Json (@mregen).
• Fixes in Encoder/Decoder found by fuzzing (@mregen).
• Fix unnecessary server Shutdown delay when no LDS is present to unregister (@romanett).

New Configuration settings:

• ChannelLifeTime is used by the server channel clean up timer.
• MaxChannelCount can be specified in the configuration to limit number of channel per server (see...)

  <MaxChannelCount>1000</MaxChannelCount>
  <ChannelLifetime>30000</ChannelLifetime>

• Configurable encoding limits

<MaxEncodingNestingLevels>200</MaxEncodingNestingLevels>
<MaxDecoderRecoveries>0</MaxDecoderRecoveries>

Breaking change:

• Encoders and Decoders should follow the Dispose pattern (so far Close was sufficient to dispose the stream)
