760e229fe7 unix: test anyToSockaddr without creating actual socket 
Test_anyToSockaddr on linux needs to create a socket with the given
domain, type and protocol in order to test anyToSockaddr. Depending on
kernel version, permission and other factors, a given combination might
not be available on the system that runs the test, as is e.g. the case
for AF_CAN/SOCK_DGRAM/CAN_J1939 on several builders after CL 272767.

The only reason to create the socket is to be able to get the socket
protocol in anyToSockaddr using GetsockoptInt(..., SO_PROTOCOL). Move
this implementation into a wrapper func which can be overriden in tests
to with a func unconditionally returning the protocol under test. This
makes the test less dependent on the system it runs on and should fix
the builders broken by CL 272767.

While at it also removed the unused SocketSpec type in
syscall_internal_bsd_test.go and remove an unnecessary error var
declaration.

zsysnum_darwin_*.go files and mark the consts as deprecated.

We can still remove these once macOS actively prevents use of direct

418715ba6f unix: compare Stat_t members when checking Stat vs. Fstatat in TestFstatat 
TestFstatat regularly fails on the dragonfly-amd64 builder due to
mismatching Stat_t info returned by the calls to Fstatat vs. Stat (most
likely due to Atime changing). Fix the test by just comparing some well
known members. This was already fixed for the Lstat call in CL 212417.

Fixes golang/go#42208

6e5568b54d unix,windows,plan9: add Byte{Slice,Ptr}ToString functions 
We already provide ByteSliceFromString and BytePtrFromString, and on
Windows we provide UTF16FromString, UTF16PtrFromString, UTF16ToString,
and UTF16PtrToString. So this commit fills in the remaining two
Byte-oriented functions: ByteSliceToString and BytePtrToString. Since
the existing two are available on windows, unix, and plan9, we add the
remaining two to the same places. This helps eliminate unsafe pointer
options in addition to triggering checkptr in Go 1.15, by eliminating
the use of prior idioms for these types of casts.
