significantly increase test coverage * add zig build option `-Dskip-libc` to skip tests that build libc (e.g. if you don't want to wait for musl to build) * add `-Denable-wine` option which uses wine to run cross compiled windows tests on non-windows hosts * add `-Denable-qemu` option which uses qemu to run cross compiled foreign architecture tests * add `-Denable-foreign-glibc=path` option which combined with `-Denable-qemu` enables running cross compiled tests that link against glibc. See https://github.com/ziglang/zig/wiki/Updating-libc#glibc for how to produce this directory. * the test matrix is done manually. release test builds are only enabled by default for the native target. this should save us some CI time, while still providing decent coverage of release builds. - add test coverage for `x86_64-linux-musl -lc` (building musl libc) - add test coverage for `x86_64-linux-gnu -lc` (building glibc) - add test coverage for `aarch64v8_5a-linux-none` - add test coverage for `aarch64v8_5a-linux-musl -lc` (building musl libc) - add test coverage for `aarch64v8_5a-linux-gnu -lc` (building glibc) - add test coverage for `arm-linux-none` - test coverage for `arm-linux-musleabihf -lc` (building musl libc) is disabled due to #3286 - test coverage for `arm-linux-gnueabihf -lc` (building glibc) is disabled due to #3287 - test coverage for `x86_64-windows-gnu -lc` (building mingw-w64) is disabled due to #3285 * enable qemu testing on the Linux CI job. There's not really a good reason to enable wine, since we have a Windows CI job as well. * remove the no longer needed `--build-file ../build.zig` from CI scripts * fix bug in glibc compilation where it wasn't properly reading the abi list txt files, resulting in "key not found" error. * std.build.Target gains: - isNetBSD - isLinux - osRequiresLibC - getArchPtrBitWidth - getExternalExecutor * zig build system gains support for enabling wine and enabling qemu. `artifact.enable_wine = true;`, `artifact.enable_qemu = true;`. This communicates that the system has these tools installed and the build system will use them to run tests. * zig build system gains support for overriding the dynamic linker of an executable artifact. * fix std.c.lseek prototype. makes behavior tests for arm-linux-musleabihf pass. * disable std lib tests that are failing on ARM. See #3288, #3289 * provide `std.os.off_t`. * disable some of the compiler_rt symbols for arm 32 bit. Fixes compiler_rt tests for arm 32 bit * add __stack_chk_guard when linking against glibc. Fixes std lib tests for aarch64-linux-gnu * workaround for "unable to inline function" using `@inlineCall`. Fixes compiler_rt tests for arm 32 bit.

Add c allocator (#542)

breaking changes to std.mem.Allocator interface API Before, allocator implementations had to provide `allocFn`, `reallocFn`, and `freeFn`. Now, they must provide only `reallocFn` and `shrinkFn`. Reallocating from a zero length slice is allocation, and shrinking to a zero length slice is freeing. When the new memory size is less than or equal to the previous allocation size, `reallocFn` now has the option to return `error.OutOfMemory` to indicate that the allocator would not be able to take advantage of the new size. For more details see #1306. This commit closes #1306. This commit paves the way to solving #2009. This commit also introduces a memory leak to all coroutines. There is an issue where a coroutine calls the function and it frees its own stack frame, but then the return value of `shrinkFn` is a slice, which is implemented as an sret struct. Writing to the return pointer causes invalid memory write. We could work around it by having a global helper function which has a void return type and calling that instead. But instead this hack will suffice until I rework coroutines to be non-allocating. Basically coroutines are not supported right now until they are reworked as in #1194.

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.
