Normalize a significant number of kernel malloc type names:

- Prefer '_' to ' ', as it results in more easily parsed results in
memory monitoring tools such as vmstat.

- Remove punctuation that is incompatible with using memory type names
as file names, such as '/' characters.

- Disambiguate some collisions by adding subsystem prefixes to some
memory types.

- Generally prefer lower case to upper case.

- If the same type is defined in multiple architecture directories,
attempt to use the same name in additional cases.

Not all instances were caught in this change, so more work is required to
finish this conversion. Similar changes are required for UMA zone names.

Use __FBSDID().

Back out M_* changes, per decision of the TRB.

Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.
Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

Modernize my email address.

Remove __P.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot). This is consistant with the other
BSD's who made this change quite some time ago. More commits to come.

$Id$ -> $FreeBSD$

kzipboot uses kern/inflate.c outside the kernel by providing its own
minimal malloc/free implementation. Stop passing M_GZIP to it.

Last major round (Unless Bruce thinks of somthing :-) of malloc changes.

Distribute all but the most fundamental malloc types. This time I also
remembered the trick to making things static: Put "static" in front of
them.

A couple of finer points by: bde

Distribute and statizice a lot of the malloc M_* types.

Removed unused #includes.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Removed unnecessary #includes of vm stuff. Most of them were once
prerequisites for <sys/sysctl.h>.

subr_prof.c:
Also replaced #include of <sys/user.h> by #include of <sys/resourcevar.h>.

Changes needed for kzip to work.

I belive imgact_gzip is finally reentrant. It is also a whole lot more
readable.

inflate is now much more general, and is there if anybody feels like making
a uncompressing filesystem or something like that (hint hint !)

- remove unnecessary #includes (I think a couple of redundant ones remain)
- excise some unused code (#if 0'd out - don't want to nuke it yet)
- fix problems with "make depend" - some macros were screwing it up
- get rid of some static local variables

There still seems to be a small reentrancy problem somewhere.

Make inflate() reentrant - no more global variables.
(The gzip image activator now needs a good code tidy up.)

First stage of getting imgact_gzip reentrant:
1) cut this up into /sys/sys/inflate.h, sys/kern/inflate.c
sys/kern/ingact_gzip.c
2) make a lot more things static
3) make a lot of globals const
4) make some args const
5) first stage of making globals into a struct (not used yet)

The vm_allocate() call which was introduced between revisions 1.4 and
1.5 of imagact_gzip.c broke things. I have backed that out for the time
being. (Davidg: help please)

WARNING: if you have gzip enabled in your kernel, you must now run
config again, as another source file has been added. Otherwise your
kernel compile will fall over.

This is all still WIP. More commits to come.
