abstracted by itry, ithrow, icatch et.al. macros
there is problem with these in stack setup for FreeBSD/ia64 at least,
and in general the rewritten explicit code is slighly more optimal
and smaller in size
the NetBSD code change is somewhat different to what was done in FreeBSD,
to improve readability of the code
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
that our lint does not understand.
One of these extensions (local labels) is needed only when using multiple
try/catch blocks within a function, and the comment before these macros
say that they should be used only once per function so that the implementaton
may be portable.
The other extension (taking the address of a label) is not needed at all.
Remove the use of the extensions.
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
