On NetBSD, for backwards compatibility, various libc symbols are
renamed to a symbol with a version suffix. For example, this is the
(abbreviated) definition of sigaction:
int sigaction(...) __asm__ ("__sigaction14")
This poses a challenge for libgo, which attempts to link sigaction by
way of an "//extern" comment:
//extern sigaction
func sigaction(...)
This results in a reference to the deprecated compatibility symbol
"sigaction", rather than the desired "__sigaction14" symbol.
This patch introduces a new "//extern-sysinfo" comment to handle this
situation. The new mklinknames.awk script scans a package for these
comments and outputs a "//go:linkname" directive that links the wrapper
to the correct versioned symbol, as determined by parsing the __asm__
annotation on the function's declaration in gen-sysinfo.go.
For now, only the following packages are scanned by mklinknames.awk:
os
os/user
runtime
syscall

Only compile the __go_ptrace varargs shim on Linux to avoid compilation
failures on some other platforms. The C ptrace function is not entirely
portable (e.g., NetBSD has `int data` instead of `void* data`), and so
far Linux is the only platform that needs the varargs shim.
Additionally, make the types in the ptrace and raw_ptrace function
declarations match. This makes it more clear that the only difference
between the two is that calls via the former are allowed to block while
calls via the latter are not.

NetBSD does not include the null terminator when in its reported socket
length. Port the upstream bugfix for the issue (#6627).
This was likely missed during the usual upstream merge because the gc
and gccgo socket implementations have diverged quite a bit.

ptrace is actually declared as a variadic function. On ppc64le
the ABI requires to the caller to allocate space for the parameters
and allows the caller to modify them.
On ppc64le, depending on how and what version of GCC is used,
it will save to parameter save area. This happened to clobber
a saved LR, and caused syscall.TestExecPtrace to fail with a timeout
when the tracee segfaults, and waits for the parent process to inspect.
Wrap this function to avoid directly calling glibc's ptrace from go.

Compiling with LTO revealed a number of cases in the runtime and
standard library where C and Go disagreed about the type of an object or
function (or where Go and code generated by the compiler disagreed). In
all cases the underlying representation was the same (e.g., uintptr vs.
void*), so this wasn't causing actual problems, but it did result in a
number of annoying warnings when compiling with LTO.

Many C syscall functions take pointer arguments. The pointers
don't escape in the C functions. Mark the C functions noescape so
calling them doesn't need allocation.

Encode all external symbol names using only ASCII alphanumeric
characters, underscore, and dot. Use a scheme that can be reliably
demangled to a somewhat readable version as described in the long
comment in names.cc.
A minor cleanup discovered during this was that we were treating
function types as different if one had a NULL parameters_ field and
another has a non-NULL parameters_ field that has no parameters. This
worked because we mangled them slightly differently. We now mangle
them the same, so we treat them as equal, as we should anyhow.
