Support OpenBSD - Document compilation instructions and code changes to support OpenBSD

[lfzamora81]

Added OpenBSD sub-section to the Dependencies section of docs/install.md.

Thanks for the PR

I wonder if these steps:

Can actually be done via the Makefile / Configure script by detecting the OpenBSD .... something to look into and then would simplify things a little further.

I am learning OpenBSD port system with eventual goal of porting this natively to OpenBSD similar to the FreeBSD port. And I will likely need to learn Autotools but my knowledge of it at the moment is almost nill--just dangerous enough to cause trouble.

I believe it would start by modifying the configure.ac to detect OpenBSD which then modifies the configure script itself to enact the OS-specific modifications ultimately for the Makefile? Or am I way over-complicating it?

I have not forgotten this PR.

I have a number of bugs / issues I need to resolve (2 x issues, 1 undocumented atm) , then I am going to spend some time looking at the relevant files on OpenBSD and try and get this to configure correctly, automatically for OpenBSD / Linux so no massaging of files is required.

No special compile options were used, in fact my main goal was to stick to the stock instructions as much as possible only deviating where absolutely necessary as documented under my submitted notes for OpenBSD. In all other aspects, I followed the build instructions from: https://github.com/abraunegg/onedrive/blob/master/docs/install.md and used the FreeBSD dependency list as a guide.

Was always wondering about the compiler differences and the fact that DMD does not need to be "activate" on OpenBSD as explained in the above instructions. At the time, LDC was still broken in the ports system so could not be tested. Not sure if that may make a difference as well.

My version is/was a bit behind now at v2.5.3-1-gaeb0a0e. I will try a fresh build from scratch soon so I can compare notes.

Please can you review this PR

I have made some significant changes to the code to support FreeBSD, and confirm that this works 100% without issue. All the documentation has also been updated regarding the support for FreeBSD.

Refer to #3048 as to the changes made to the code to support FreeBSD.

I have confirmed that the current 'master' compiles without any code change / Makefile change or other under OpenBSD:

I have updated 'install.md' with the details augmented from your initial work.

Now .. what works / does not work

Authentication - works

Application Runtime - DOES NOT WORK .....

The code is correct ... works without issue on Linux and FreeBSD.

I have a feeling this has something to do with internal OpenBSD process memory management / memory allocation .. as the data that is in the JSON is there .. just under OpenBSD it cannot be read.

Please can you investigate this.
