Our new-old mbugf allocator. This is actually something of a blast from
the past, since it returns to the old system of allocating mbufs out of
a private area rather than using the kernel malloc(). While this may seem
like a backwards step to some, the new allocator is some 20% faster than
the old one and has much better caching properties.

Import 4.4BSD-Lite2 onto the vendor branch, note that in the kernel, all
files are off the vendor branch, so this should not change anything.

A "U" marker generally means that the file was not changed in between
the 4.4Lite and Lite-2 releases, and does not need a merge. "C" generally
means that there was a change.
[note new unused (in this form) syscalls.conf, to be 'cvs rm'ed]

A Major staticize sweep. Generates a couple of warnings that I'll deal
with later.
A number of unused vars removed.
A number of unused procs removed or #ifdefed.

Untangled the vm.h include file spaghetti.

Completed function declarations and/or added prototypes.

Finished (?) cleaning up sysinit stuff.

Second batch of cleanup changes.
This time mostly making a lot of things static and some unused
variables here and there.

Fixed init functions argument type - caddr_t -> void *. Fixed a couple of
compiler warnings.

they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the
'files' file.

Eliminate sloppy common-style declarations. There should be none left for
the LINT configuation.

Special cased the handling of mb_map in the M_WAITOK case. kmem_malloc()
now returns NULL and sets a global 'mb_map_full' when the map is full.
m_clalloc() has further been taught to expect this and do the right thing.
This should fix the "mb_map full" panics that several people have reported.

Implemented mbstat.m_wait and mbstat.m_drops.

Update kmem_malloc() call to new waitflag(s) interface.

This might fix recent problems on thud and freefall.

Got rid of map.h. It's a leftover from the rmap code, and we use rlists.
Changed swapmap into swaplist.

Moved m_copyback into uipc_mbuf.c

All of this is cosmetic. prototypes, #includes, printfs and so on. Makes
GCC a lot more silent.
