FreeBSD doesn't mount procfs as default on the base system, so we can't
depend on it to get the current path, In this case, we use sysctl(3) to
retrieves the system information and get the same information.
- CTL_KERN: High kernel limits
- KERN_PROC: Return selected information about specific running
processes.
- KERN_PROC_PATHNAME: The path of the process
- Process ID: a process ID of -1 implies the current process.
The system call getrandom(2) just landed on FreeBSD 12, so if we want to
support some earlier version or at least FreeBSD 11, we can't depend on
the system call.
* add `@bswap` builtin function. See #767
* comptime evaluation facilities are improved to be able to
handle a `@ptrCast` with a backing array.
* `@truncate` allows "truncating" a u0 value to any integer
type, and the result is always comptime known to be `0`.
* when specifying pointer alignment in a type expression,
the alignment value of pointers which do not have addresses
at runtime is ignored, and always has the default/ABI alignment
* threw in a fix to freebsd/x86_64.zig to update syntax from
language changes
* some improvements are pending #863closes#638closes#1733

Relevant #764
dwarf debug info is modified to use this instead of std.os.File
directly to make it easier for bare metal projects to take advantage
of debug info parsing
FreeBSD appears to use rdi instead of rsp as in other posix systems.
According to some loose documentation, x86 passes values on the stack,
so amd64 freebsd may be the only exception.
closes#1414
std.io.InStream.read now can return less than buffer size
introduce std.io.InStream.readFull for previous behavior
add std.os.File.openWriteNoClobberC
rename std.os.deleteFileWindows to std.os.deleteFileW
remove std.os.deleteFilePosix
add std.os.deleteFileC
std.os.copyFile no longer takes an allocator
std.os.copyFileMode no longer takes an allocator
std.os.AtomicFile no longer takes an allocator
add std.os.renameW
add windows support for std.os.renameC
add a test for std.os.AtomicFile
* error.BadFd is not a valid error code. it would always be a bug to
get this error code.
* merge error.Io with existing error.InputOutput
* merge error.PathNotFound with existing error.FileNotFound.
Not all OS's support both.
* add os.File.openReadC
* add error.BadPathName for windows file operations with invalid
characters
* add os.toPosixPath to help stack allocate a null terminating byte
* add some TODOs for other functions to investigate removing the
allocator requirement
* optimize some implementations to use the alternate functions when
a null byte is already available
* add a missing error.SkipZigTest
* os.selfExePath uses a non-allocating API
* os.selfExeDirPath uses a non-allocating API
* os.path.real uses a non-allocating API
* add os.path.realAlloc and os.path.realC
* convert many windows syscalls to use the W versions (See #534)
