sigaltstack(2): document some modernizations:

2010-05-06T22:06:14+00:00

* un-document 'struct sigaltstack' tag for stack_t as this is BSD-specific;
  this doesn't seem useful enough to document as such
* alternate stacks are per thread, not per process
* update error codes to what the kernel does and POSIX requires

mdoc(7) police: Tidy up the syscall language.

Stop calling system calls "function calls".

Use "The .Fn system call" a-la "The .Nm utility".

When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.

Add the 'restrict' type qualifier to the prototypes of `sigaction',

`sigprocmask', `sigaltstack', and `sigwait' as well as to the
prototypes of the apparantly unimplemented functions `sigtimedwait'
and `sigwaitinfo'.  This complies with IEEE Std 1003.1-2001.

Adjust to reflect reality, which is that sigaltstack() takes stack_t *'s.
