introduce operating system version ranges as part of the target * re-introduce `std.build.Target` which is distinct from `std.Target`. `std.build.Target` wraps `std.Target` so that it can be annotated as "the native target" or an explicitly specified target. * `std.Target.Os` is moved to `std.Target.Os.Tag`. The former is now a struct which has the tag as well as version range information. * `std.elf` gains some more ELF header constants. * `std.Target.parse` gains the ability to parse operating system version ranges as well as glibc version. * Added `std.Target.isGnuLibC()`. * self-hosted dynamic linker detection and glibc version detection. This also adds the improved logic using `/usr/bin/env` rather than invoking the system C compiler to find the dynamic linker when zig is statically linked. Related: #2084 Note: this `/usr/bin/env` code is work-in-progress. * `-target-glibc` CLI option is removed in favor of the new `-target` syntax. Example: `-target x86_64-linux-gnu.2.27` closes #1907

Add illumos OS tag - Adds `illumos` to the `Target.Os.Tag` enum. A new function, `isSolarish` has been added that returns true if the tag is either Solaris or Illumos. This matches the naming convention found in Rust's `libc` crate[1]. - Add the tag wherever `.solaris` is being checked against. - Check for the C pre-processor macro `__illumos__` in CMake to set the proper target tuple. Illumos distros patch their compilers to have this in the "built-in" set (verified with `echo | cc -dM -E -`). Alternatively you could check the output of `uname -o`. Right now, both Solaris and Illumos import from `c/solaris.zig`. In the future it may be worth putting the shared ABI bits in a base file, and mixing that in with specific `c/solaris.zig`/`c/illumos.zig` files.

move some of the installation from cmake to zig build This moves the installation of shipped source files from large CMakeLists.txt lists to zig build recursive directory installation. On my computer a cmake `make install` takes 2.4 seconds even when it has to do nothing, and prints a lot of unnecessary lines to stdout that say "up-to-date: [some file it is installing]". After this commit, the default output of `make` is down to 1 second, and it does not print any junk to stdout. Further, a `make install` is no longer required and `make` is sufficient. This closes #2874. It also closes #2585. `make` now always invokes `zig build` for installing files and libuserland.a, and zig's own caching system makes that go fast.

std: correct getcontext for Android bionic libc I have updated Felix's ZigAndroidTemplate to work with the latest version of Zig and we are exploring adding Android support to Mach engine. `std.c.getcontext` is _referenced_ but not _used_, and Android's bionic libc does not implement `getcontext`. `std.os.linux.getcontext` also cannot be used with bionic libc, so it seems prudent to just disable this extern for now. This may not be the perfect long-term fix, but I have a golden rebuttal to that: before I was unable to compile Zig applications for Android, and now I can. <img width="828" alt="image" src="https://github.com/hexops/mach/assets/3173176/1e29142b-0419-4459-9c8b-75d92f87f822"> Signed-off-by: Stephen Gutekanst <stephen@hexops.com>
