The internal architecture name of golang is "arm" or "arm64", which has
different naming conventions from netbsd's machine[] or machine_arch[]
("earmv7", "aarch64", etc.) and cannot be used as is.
Instead, use define LINUX_GO_RT0_SIGNATURE_ARCH{32,64}.

- LINUX_GO_RT0_SIGNATURE for compat_linux is no longer enabled by default.
it is now defined in each arch same as the other *_SIGNATURE definitions.
- add new LINUX32_GO_RT0_SIGNATURE for compat_linux32, and is defined in amd64 and aarch64.

Attempt to fix the mess.

Initial support for linux compat on the alpha. Not quite working.

Always clear FUTEX_PRIVATE_FLAG for Linux processes. NetBSD-native futexes
exist in different namespace depending on FUTEX_PRIVATE_FLAG. This appears
not to be the case in Linux, and some futex users will mix private and non-
private ops on the same futex object. Provide a convenience wrapper that
puts this logic in one place witn a comment explaining why.

While here, move the Linux futex wrapper out of its own file and plop
it in linux_misc.c, which is where it lives in the linux32 module.

Remove Alpha's compat_linux dependency on compat_osf1. Each function is
copied as-is from compat_osf1 with no functional change. Discussed on

For amd64, it implements vsyscalls through cheating: if the faulting
address is in the vsyscall area (which is statically known on Linux/amd64),
and the intruction pointer is too, it must have been a vsyscall. In that
case, retrieve the return address from the user stack, fix up %rip and
%rsp, and just execute the normal system call. It will return as if
the vsyscall has been executed.

Add kernel support for having userland provide the signal trampoline:

* struct sigacts gets a new sigact_sigdesc structure, which has the
sigaction and the trampoline/version. Version 0 means "legacy kernel
provided trampoline". Other versions are coordinated with machine-
dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions. Instead,
sendsig() looks up the handler by peeking in the sigacts for the
process getting the signal (since it has to look in there for the
trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later. Kernel
version not bumped; we will ride the 1.6C bump made recently.

Refactor pipe1() and correct a bug in sys_pipe2() (SYS_pipe2)

sys_pipe2() returns two integers (values), the 2nd one is a copy of the 2nd
file descriptor that lands in fildes[2]. This is a side effect of reusing
the code for sys_pipe() (SYS_pipe) and not cleaning it up.

The first returned value is (on success) 0.

Introduced a small refactoring in pipe1() that it does not operate over
retval[], but on an array int[2]. A user sets retval[] for pipe() when
desired and needed.

This refactoring touches compat code: netbsd32, linux, linux32.

Before the changes on NetBSD/amd64:

$ ktruss -i ./a.out
[...]
15131 1 a.out pipe2(0x7f7fff2e62b8, 0) = 0, 4
[...]

After the changes:

$ ktruss -i ./a.out
[...]
782 1 a.out pipe2(0x7f7fff97e850, 0) = 0
[...]

There should not be a visible change for current users.

Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
