Refactor term functions and update for Zig 0.17

[cers000]

主要是@cImport被移除了，通过addTranslateC自动转义生成的translate_c.zig并不好用，很多翻译的zig代码有问题，比如

pub const stdin = __acrt_iob_func(@as(c_int, 0));
pub const stdout = __acrt_iob_func(@as(c_int, 1));
pub const stderr = __acrt_iob_func(@as(c_int, 2));

这些代码在zig build的compile阶段过不了编译器，因为error: comptime call of extern function

我仔细看了这些代码，没有问题，在Windows 10 64bit，zig 0.17.0-dev.657+2faf8debf，可以正常构建，生成了正常的.\zig-out\bin\mqjs.exe程序，并正常运行

Zig 0.17 is the master branch. It is unstable and constantly changing. So I'm not targeting it.

Andrew Kelley自己说的几周内就会发布zig0.17，目前这个库仍有需要完善的地方，尤其是readline_tty.zig似乎可以摆脱c头文件引入，等这些完善了，zig0.17就已经发布了，正好可以承载新版本带了的构建速度优势。

If you’re someone who wants to influence the direction of Zig, this is a good time to upgrade your projects to the development version and try out these changes. We’ll be releasing 0.17.0 within a couple weeks from now. However, if you don’t have time, and you find out that 0.17.0 broke your build, don’t worry, there will be plenty of opportunity to get fixes in for the 0.17.1 tag as well.

Ok. Well I'm not going to merge this until 0.17 is released, but I guess I'll reopen the pull request until then
