Linux specific fixes

.NET Fixes

• Shorten the name of .NET threads. Fixes GitHub issue #24
• Provide an implementation for DiscardInBuffer and DiscardOutBuffer. Fixes GitHub issue #26
• Make P/Invoke safer with the SafeHandle.
• Properly clean up pin monitoring thread.

Changes since libnserial-1.1.1

• Don't monitor pins for devices that don't support it (e.g. /dev/ttyACM devices), avoiding a 100% CPU issue. Fixes GitHub issue #22
• Treat the OS return EINTR as an interrupt and not an error, no longer crashing.
• Fix race conditions when monitoring pins.
• Fix handling of pthread errors.

Windows specific fixes

• Support the Arduino Uno clone with a USB CH340 serial/usb adaptor. This driver doesn't suppot WaitCommEvent overlapped. Fixes GitHub issue #25

libnserial

Changes since version 2.0.3.0

• Refactor code for better framework multitargetting. Due to a build configuration failure, .NET Standard 1.5 is not working in this release
• On Linux use a smarter algorithm than Mono for getting available serial ports. Needs libnserial-1.1.0. In case an older libnserial is installed, we revert to older behaviour in SerialPortStream 2.0.3. NET Standard on Windows returns an empty list, but will work properly on Linux.
• Enrich exception handling. Needs libnserial-1.1.0. In case an older libnserial is installed, we revert to older behaviour in SerialPortStream 2.0.3. This may cause a breaking change as new exceptions may be raised for existing APIs.

It is recommended to also update the library libnserial to version 1.1.0 for this release to get all features.
