9f0482e515 Add support for COMPAT6 syscalls.
Also, change the visibility of compat syscalls a slightly.  Compat
syscalls were missing from 'syscalls.h' entirely.  This additionally adds
them with their compat prefix.  eg: SYS_freebsd6_mmap.

Also, the syscalls.c names strings have different prefixes to differentiate
syscalls. Instead of several "old.mmap" strings, there will now be a
"compat.mmap" and "compat6.mmap" etc.  Before, both would have had the
same "old.mmap" label.

52a79796c4 Add a new set of macros <prefix>_AUE_<syscallname> to sysproto.h that
map to the audit event associated with a specific system call.  For
example, SYS_AUE___semctl would be set to AUE_SEMCTL in sys/sysproto.h.

af5bf12239 Now that all system calls are MPSAFE, retire the SYF_MPSAFE flag used to
mark system calls as being MPSAFE:
- Stop conditionally acquiring Giant around system call invocations.
- Remove all of the 'M' prefixes from the master system call files.
- Remove support for the 'M' prefix from the script that generates the
  syscall-related files from the master system call files.
- Don't explicitly set SYF_MPSAFE when registering nfssvc.

f3596e3370 Introduce a new field in the syscalls.master file format to hold the
audit event identifier associated with each system call, which will
be stored by makesyscalls.sh in the sy_auevent field of struct sysent.
For now, default the audit identifier on all system calls to AUE_NULL,
but in the near future, other BSM event identifiers will be used.  The
mapping of system calls to event identifiers is many:one due to
multiple system calls that map to the same end functionality across
compatibility wrappers, ABI wrappers, etc.

1a58b07149 Remove the namespace column from the syscalls tables. We don't actually
use it, if we ever did.  They have been been VERY poorly maintained for
some time, possibly because they were a NOP.  FWIW, This brings our table
formats back closer to the other *BSD's.

49ead724c6 Fix breakage caused by previous commit. The lkmnosys and lkmressys
syscalls are of type NODEF but not in a way that fits the given
definition of that type. The exact difference of lkmressys and
lkmnosys is unclear, which makes it all the more confusing. A
reevaluation of what we have and what we really need is in order.

4166877345 Make the NODEF type usable. A syscall of type NODEF will only
have its entry in the syscall table added. Nothing else is
done. This differs from type NOPROTO in that NOPROTO adds a
definition to syscall.h besides adding a sysent. A syscall can
now have multiple entries without conflict. Note that the
argssize is fixed and depends on the syscall name.

356861db03 Remove the MPSAFE keyword from the parser for syscalls.master.
Instead introduce the [M] prefix to existing keywords.  e.g.
MSTD is the MP SAFE version of STD.  This is prepatory for a
massive Giant lock pushdown.  The old MPSAFE keyword made
syscalls.master too messy.

Begin comments MP-Safe procedures with the comment:
/*
 * MPSAFE
 */
This comments means that the procedure may be called without
Giant held (The procedure itself may still need to obtain
Giant temporarily to do its thing).

sv_prepsyscall() is now MP SAFE and assumed to be MP SAFE
sv_transtrap() is now MP SAFE and assumed to be MP SAFE

ktrsyscall() and ktrsysret() are now MP SAFE (Giant Pushdown)
trapsignal() is now MP SAFE (Giant Pushdown)

Places which used to do the if (mtx_owned(&Giant)) mtx_unlock(&Giant)
test in syscall[2]() in */*/trap.c now do not.  Instead they
explicitly unlock Giant if they previously obtained it, and then
assert that it is no longer held to catch broken system calls.

Rebuild syscall tables.

6b972e0bdd Fixed the calculation of sy_nargs in sysent tables. We attempted to do
this in awk using the hack of counting args of type off_t twice and args
of all other types once.  This is too simple to work.  It gave benignly
wrong results on alphas (off_t shouldn't be counted twice) and for
svr4_sys_mmap64() on i386's (off64_t should be counted twice).  It gave
fatally wrong results for i386's with 64-bit longs (longs should be
counted twice).  The correct value for sy_nargs is easier to determine
from the size of the args struct anyway, except for complications to
make the generated code almost readable.

Improved formatting of sysent tables by lining up the comments where
possible.

cbe0799aaf Add statements to generate a sys/syscall.mk file for inclusion
during the libc/libc_r to automatically pick up syscall names on
the assumption that default asm code needs to generated for them.

In the up-coming changes to the libc makefiles, there is the option
to provide a machine dependent asm source file which will turn off
the automatic generation of the default. There is also an option
to just stop code being generated for a syscall. In most cases,
though, the default asm code is all that is required, so this
change makes that the most convenient was to do business.
