738824ad6c As new objects begin to support new labels, start to generalize
the default label support in /etc/mac.conf.  Rather than maintain
each default label type in an explicit global variable in mac.c,
keep a list of defaults loaded from the configuration file.
Generalize the parsing so that we support both the older:

        default_file_labels foo
        default_ifnet_labels foo
        default_process_labels foo

And also a new:

        default_labels file foo
        default_labels ifnet foo
        default_labels process foo

We now accept arbitrary object classes in the first argument.  If
the same object is specified more than once, we discard the
earlier definition in favor of the later one.

Add a new API, mac_prepare_type(), which accepts a mac_t to
prepare, as well as an object name in the second argument, which
will pull a default label set for the object out of the
configuration loaded by mac_init_internal().  This permits the libc
to adapt to new objects known about by applications but not by libc
at compile-time.

Also liberalize the error handling a bit: if we're using implicit
initialization (i.e., the application didn't explicitly initialize
the MAC code), ignore syntax errors and only use valid lines.  In
the future, we may want to add explicit warnings and do this a
bit more consistently.

While here, add support for a MAC_CONFFILE environmental variable,
which may be used to specify an alternative mac.conf configuration
file if the application isn't running with modified privilege
(issetugid()).

2d81cd746b _thr_sig_check_pending is also called by scope system thread when it leaves
critical region, we wrap some syscalls for thread cancellation point, and
when syscalls returns, we call _thr_leave_cancellation_point, at the time
if a signal comes in, it would be buffered, and when the thread leaves
_thr_leave_cancellation_point, buffered signals will be processed, to avoid
messing up normal syscall errno, we should save and restore errno around
signal handling code.

89a26fd1fc Add a kluge suggested by Marcel to paper over the difference between
gethostname()'s old and new signatures without requiring a library
bump.  Note that programs which called gethostname() with a negative
argument were already broken, since the same type conversion was done
by the old implementation.  Add a note in the Makefile so that whoever
next bumps the libc revision will delete the kluge at the same time
(as it will no longer be necessary).  This is only operative on 64-bit
platforms.

effcb5eca3 Change gethostname() to set errno to ENAMETOOLONG instead of ENOMEM
when the buffer is not long enough to hold the current host name.
POSIX does not standardize error returns for gethostname(), so it
doesn't matter which one we use, but ENAMETOOLONG is at least a little
more intuitive, and mi suggests the existence of prior art.  I've been
running with this change for a while on my home machine with no
effect.  At the same time, I've updated the prototype for
gethostname() to use the correct standard type (size_t) for the
namelen argument.

All of the in-tree callers fall into one of the following categories:
1) Call perror() or equivalent when gethostname() fails.
2) Ignore gethostname()'s return value entirely, potentially resulting
in data corruption if the buffer is too small.
3) Fall back to a (possibly sensible) default value if gethostname()
fails.

Many of the callers I examined shows signs of confusion about the
correct sizing of the host name buffer.  gethostname(3) now has more
information about this, as well as updated standards information.

abd498aa71 Add the mlockall() and munlockall() system calls.
- All those diffs to syscalls.master for each architecture *are*
   necessary. This needed clarification; the stub code generation for
   mlockall() was disabled, which would prevent applications from
   linking to this API (suggested by mux)
 - Giant has been quoshed. It is no longer held by the code, as
   the required locking has been pushed down within vm_map.c.
 - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES
   to express their intention explicitly.
 - Inspected at the vmstat, top and vm pager sysctl stats level.
   Paging-in activity is occurring correctly, using a test harness.
 - The RES size for a process may appear to be greater than its SIZE.
   This is believed to be due to mappings of the same shared library
   page being wired twice. Further exploration is needed.
 - Believed to back out of allocations and locks correctly
   (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).

o Properly mask the passed or returned fp_except_t. Not doing so
