471940b943 unix: add Sockaddr implementation for J1939 
Currently, only the raw socketcan are supported. In newer kernel versions, the sockaddr_can
structure has been extended to also support J1939 protocol, as seen in the C structure (https://elixir.bootlin.com/linux/latest/source/include/uapi/linux/can.h#L171):

struct sockaddr_can {
	__kernel_sa_family_t can_family;
	int         can_ifindex;
	union {
		struct { canid_t rx_id, tx_id; } tp;
		struct {
			__u64 name;
			__u32 pgn;
			__u8 addr;
		} j1939;
} can_addr;

c5abc1b1d3 unix: revert zsysnum_darwin_*.go deletion from CL 250437 
CL 250437 removed the zsysnum_darwin_*.go files containing the SYS_*
contants for macOS. This was done assuming that users should migrate
away from direct syscalls to libSystem wrappers. Let's not force users
of this package on when they want to do that and re-add the
zsysnum_darwin_*.go files and mark the consts as deprecated.

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

BSD platforms but darwin.

e075d93706 unix: deflake TestPselect and TestSelect on linux 
On some platforms (namely Linux), Select and Pselect update the
passed-in timeval/timespec, which might lead to failing tests in
case of an EINTR. Fix this by always resetting the timeval/timespec
before calling Select/Pselect.

Also change accept timeouts within 2/3 margin of the expected timeout,
like already done in TestSelect. While at it, fix the failure log to use
the common "got X, expected Y" message.

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.

4d22bbb62b unix: remove darwin support from mksysnum.go 
Since CL 250437 this package no longer supports non-libc, direct
syscalls on darwin. Thus support for generating zsysnum_*.go files on
darwin can be removed from the generating mksysnum.go program.

9d91bd6205 unix: implement Getwd using getcwd from libSystem on darwin 
Directly wrap the getcwd implementation provided by libSystem.dylib on
darwin and use it to implement Getwd like on the BSDs. This allows to
drop the custom implementation using getAttrList and to merge the
implementation of Getwd for darwin and the BSDs in syscall_bsd.go.

cb7fb32132 unix: allow overriding GOOS using GOOS_TARGET in mksyscall.go 
The syscall wrapper generator utility is platform independent and can in
principle be run on a GOOS other than the one we're generating the
syscall wrappers for. Allow overriding GOOS by setting GOOS_TARGET,
similar to other generator programs in the repo.

Also remove the unused GOARCH_TARGET override in the same file.
