update to zig 0.14.0-dev.2952+8fa47bb90

[leroycep]

I also did a major refactor of the build.zig, let me know if you don't want those changes in this pull request 😅

Also, I've only tested this on linux, so I have no idea if the other backends need updating, I just made sure zig build and zig build test worked.

Links to relevant changes upstream (not including std.Build):

• remove @fence()
• tv_ prefix removed from linux.timespec in std.c reorganization
• linux.timerfd_create now accepts clockid_t enum in std.c reorganization
• linux.clockid_t is now a non-exhaustive enum in std.c reorganization

@leroycep do you think this is the source of the error I have while trying to build libxev as a dependency here? #140

[Zorgatone]

I still get an error here, I can try to see if I'm able to fix it:

zig:99:18: error: expected 2 argument(s), found 1
        if (posix.clock_gettime(posix.CLOCK.MONOTONIC)) |new_time| {

Actually, updating from Zig 0.14.0-dev.2989+bf6ee7cb3 to Zig 0.14.0-dev.3036+7ac110ac2 fixed the error for me

[leroycep]

Yeah I updated it to latest master, unfortunately that made it incompatible with earlier versions. If you want to use an earlier version of Zig you can pin to the earlier commit.

While I'm here, relevant upstream changes:

• clock_gettime changed to return value instead of taking out pointer in std.posix: Rewriting enums to seperate clock IDs for clock_gettime() and timerfd_create() - Follow-up

Just to be aware, this doesn't work on MacOS since the kqueue backend hasn't been changed. There is also a smaller issue that most of the darwin namespace is not published.

If it helps, I have already patched libxev in my fork to make it work with Zig 0.14.x even on MacOS. I haven't really made a pull request yet since Zig 0.14 hasn't been tagged yet

[leroycep]

I might pull in your changes if that's all right. And I hope your pull request to fix the darwin namespace get's merged, otherwise libxev might have to copy paste the darwin definitions.

My philosophy for this pull request is more "put it out there so other's can find it". I figure mitchell can ignore it until then 😄
