Update WiringPi to run into Raspbian Buster and Raspberry Pi 4B

[k3z0]

It is necessary to use a new version of WiringPi 2.52 in order to get the library working in Raspbian Buster and the Raspberry Pi 4B.

I was modifying the latest version of WiringPi available in its repository. I need to make some custom changes in order to support the second SPI bus available in the Raspberry Pi (spidev1.0). I already compiled the library, nevertheless, I couldn't make it properly run in the Raspberry.

I will continue working to solve this issue.

We already update to use WiringPi 2.50 but it is not clear when will the sources for version 2.52 be available. We could use version 2.52 without the custom SPI changes following the instructions here

It is not clear if the last version of WiringPi will be available since the author said that WiringPi is now deprecated.

k3z0,
If someone would publish a fork of the latest available version, perhaps your copy of the 2.50 download, onto github, a community could take over the responsibility of maintaining a fork of wiringpi, so that Gordon doesn't receive more interruptions.
It should probably be renamed, with credit to wiringPi and to Gordon, so it's clearly not supported by him.

I'd hate to see the project die.

@k3z0 Could you please publish the latest release to nuget as to support the Raspberri Pi 4B properly? I tried manually using the latest source in my project and then my project ran without issues.

You can check version 0.5.1 (https://www.nuget.org/packages/Unosquare.WiringPi/0.5.1)

It looks like Unosquare.WiringPi Version 0.5.1 uses libwiringPi.so.2.52. What source was used to compile the 2.52 version of wiring pi? Was it from https://project-downloads.drogon.net (seems it is now taken down)?

I found this git: https://github.com/WiringPi/WiringPi , but they've jumped from 2.50 to 2.60. I tried changing the version number to 2.52 and re-compiling it, it output a file named libwiringPi.so.2.52, and `sudo gpio -v' shows the version as 2.52, but I still get an error:

 System.DllNotFoundException: Unable to load shared library 'libwiringPi.so.2.52' or one of its dependencies.
