Support newer FUSE APIs

[Gentoli]

Environment

• Windows version: 10.0.25281.1000
• Processor architecture: x86_64
• Dokany version: 2.0.6.1000
• Library type (Dokany/FUSE): FUSE

Description

I am trying to compile s3fs-fuse with dokanfuse2. It requires fuse >= 2.8.4 but the fuse version defined in pkg-config.pc.in is 2.6.0.

According to libfuse release tags, FUSE 2.9.4 is released around end of 2015 and 3.0 in the end of 2016. I think dokanfuse2 should at least support all 2.x or even 3.x.

Logs

Some compilation error logs when dokanfuse2 version is manually set:

Hi @Gentoli ,

Indeed, this is a good idea. There is an issue already open for this feature here https://github.com/dokan-dev/dokany/issues/182. I would be glad to review and help any contribution!
