Various Linux fixes

[Mystro256]

Three fixes/commits:

• Use shared gtest library if available, which is appliable for some Linux distros, such as Fedora, see bug report:
  https://bugs.dolphin-emu.org/issues/9402
• Fixes to suse/fedora spec file: version bump to 5.0 and polarssl should be mbedtls
• Added manpages for Linux systems, see bug report:
  https://bugs.dolphin-emu.org/issues/9403

Thanks!

I don't think the version bump is necessary, 5.0 hasn't come out yet

[Mystro256]

Considering it's the development branch and 5.0RC has been tagged, I figured it could be safely changed. If not, just cherry pick out that commit. The only other thing I changed in the commit was polarssl -> mbedtls, as the package was renamed in Fedora.

[Helios747]

The RC system was scrapped.

[Mystro256]

I've made some changes based on the input provided:

• Reverted back to 4.0.2 in the spec
• Used dolphin's homepage description in the manpages instead

Feel free to squash those last 3 changes into their respective commits to keep things tidy.

Comments from the review on Reviewable.io

[Mystro256]

Done, squashed into 3 commits.
Also fixed manpage issues as described above, except one issue:

• Sort the list of options: I think just having the options in the order specified in the README and code would be the most consistent choice here. There's no de facto rule when it comes to options sorting, so I don't think it really matters, as it's still legible.

Google Test recommends against using precompiled system libararies, are you sure this is a good idea?

[jcowgill]

And then you have other distros (such as Debian / Ubuntu) which ship a shared copy of the source only in /usr/src/gtest to get around the issues Google raised. Should these distros be supported too?

[delroth]

In practice there is no reason to care about GTest being statically linked. It's not linked into our main binary, only in unit tests that aren't being distributed to end users.

So I would recommend reverting that part of the pull request and keeping the static linking to our Externals copy.

[Mystro256]

I changed shared gtest to be an option that's disabled by default.

I can't make a solution for Debian or Ubuntu, as I don't use these distros and can't test this properly. If desired, an extra check can be added later.

[Mystro256]

Alright, I've moved the manpages to Data, and in a separate commit, I moved the Linux specific data files to Data as well.

This adds 5 files to the Windows build. Is that intended?

[Mystro256]

No, I'm assuming this is an error in the windows build, where it includes everything from the Data folder (Note that I am not a windows user or developer). The windows build needs to be changed to exclude these files and not just copy the hold Data folder.
