troubles with caps

Hi all,

I'm having a lot of problems trying to use caps.  Thanks to Joerg's work
last night, libcaps does build.  However, it does not build correctly. 
There's some sort of issue with sys/kern/lwkt_msgport.c not being
properly buildable in userland.  The relevant part of the build log
(full log attached):

 cc -O -pipe  -I/usr/src/lib/libcaps/.. -I/usr/src/lib/libcaps/i386
-DSMP -D_UTHREAD -Wall -g -DCAPS_DEBUG  -c
/usr/src/lib/libcaps/../../sys/kern/lwkt_msgport.c -o lwkt_msgport.o
 /usr/src/lib/libcaps/../../sys/kern/lwkt_msgport.c: In function
`lwkt_abortmsg':
 /usr/src/lib/libcaps/../../sys/kern/lwkt_msgport.c:461: warning:
implicit declaration of function `cpu_mb1'
 /usr/src/lib/libcaps/../../sys/kern/lwkt_msgport.c: In function
`lwkt_default_waitport':
 /usr/src/lib/libcaps/../../sys/kern/lwkt_msgport.c:596: warning:
implicit declaration of function `CURSIG'

This results in an unusable libcaps .so (see attached caps-test log.)

I made a few lame attempts at fixing it by adding the header files
<sys/signalvar.h> and <sys/cpufunc.h> to lwkt_msgport.c outside of
#ifdef _KERNEL, but that just caused even more obscure errors when
#trying to #define _KERNEL_STRUCTURES in libcaps itself...

Hoping this report is sort of useful to anyone with the knowledge and
inclination to fix it, it would be nice to have userland caps again! :)

Thanks in advance,
-Chris
