breaking: std.os read/write functions + sendfile 
* rework os.sendfile and add macosx support, and a fallback
   implementation for any OS.
 * fix sendto compile error
 * std.os write functions support partial writes. closes #3443.
 * std.os pread / pwrite functions can now return `error.Unseekable`.
 * std.fs.File read/write functions now have readAll/writeAll variants
   which loop to complete operations even when partial reads/writes
   happen.
 * Audit std.os read/write functions with respect to Linux returning
   EINVAL for lengths greater than 0x7fff0000.
 * std.os read/write shim functions do not unnecessarily loop. Since
   partial reads/writes are part of the API, the caller will be forced
   to loop anyway, and so that would just be code bloat.
 * Improve doc comments
 * Add a non-trivial test for std.os.sendfile
 * Fix std.os.pread on 32 bit Linux
 * Add missing SYS_sendfile bit on aarch64

std: implement sendfile on linux 
This changset adds a `sendfile(2)` syscall bindings to the linux bits
component. Where available, the `sendfile64(2)` syscall will be
transparently called.

A wrapping function has also been added to the std.os to transform
errno returns to Zig errors.

std.Thread.cpuCount on Windows uses the PEB 
rather than calling GetSystemInfo from kernel32.dll. Also remove
OutOfMemory from the error set.

C pointer slices are no longer allowzero (#4462) 
* Slices from C pointers are no longer allowzero but instead insert a runtime assertion.

* Added a test, fixed code for cases with non-allowzero C pointers

* Create new type when flipping allow_zero, sometimes we get a cached value back from adjust_ptr_len.

* Added comments, changed panic message

* Added runtime safety test.

native things, leaving explicitly overridden things alone.
