Hopefully, now it is more clear that the memory referenced by the
ptr argument of realloc(ptr,size) is freed and only the return value
of realloc() points to a valid memory area upon successful completion.

__dlfunc_t to dlfunc_t to match what I have proposed to the Austin
Group. (This also makes it easier for applications to store these
values before they decide what to do with them, e.g., in a wrapper
function.)
Add new dlfunc() interface, which is a version of dlsym() with a
return type that can be cast to a function pointer without turning
your computer into a frog.

The uuidgen command, by means of the uuidgen syscall, generates one
or more Universally Unique Identifiers compatible with OSF/DCE 1.1
version 1 UUIDs.
From the Perforce logs (change 11995):
Round of cleanups:
o Give uuidgen() the correct prototype in syscalls.master
o Define struct uuid according to DCE 1.1 in sys/uuid.h
o Use struct uuid instead of uuid_t. The latter is defined
in sys/uuid.h but should not be used in kernel land.
o Add snprintf_uuid(), printf_uuid() and sbuf_printf_uuid()
to kern_uuid.c for use in the kernel (currently geom_gpt.c).
o Rename the non-standard struct uuid in kern/kern_uuid.c
to struct uuid_private and give it a slightly better definition
for better byte-order handling. See below.
o In sys/gpt.h, fix the broken uuid definitions to match the now
compliant struct uuid definition. See below.
o In usr.bin/uuidgen/uuidgen.c catch up with struct uuid change.
A note about byte-order:
The standard failed to provide a non-conflicting and
unambiguous definition for the binary representation. My initial
implementation always wrote the timestamp as a 64-bit little-endian
(2s-complement) integral. The clock sequence was always written
as a 16-bit big-endian (2s-complement) integral. After a good
nights sleep and couple of Pan Galactic Gargle Blasters (not
necessarily in that order :-) I reread the spec and came to the
conclusion that the time fields are always written in the native
by order, provided the the low, mid and hi chopping still occurs.
The spec mentions that you "might need to swap bytes if you talk
to a machine that has a different byte-order". The clock sequence
is always written in big-endian order (as is the IEEE 802 address)
because its division is resulting in bytes, making the ordering
unambiguous.

Make use of the new INSFPdq_RN macro where apporpriate; this
is required for correctly handling the "high" fp registers
(>= %f32).
Fix a number of bugs related to the handling of the high registers
which were caused by using __fpu_[gs]etreg() where __fpu_[gs]etreg64()
should be used (the former can only access the low, single-precision,
registers).

on long double, which are not implemented in hardware on any UltraSPARC
chip that I know of. This just calls into the existing floating point
emulator, which is still needed to emulate other floating point operations
in certain conditions. Without this gcc has to generate the quad floating
point instructions directly, which sometimes causes internal compiler
errors.

Emulate popc in the user trap handler as well.
Re-arrange slightly to make support functions more accessible.

- %a/%A (exact hex representation of floating-point numbers)
Removed old compatability equivalents:
- %D for %ld, %O for %lo, %X for %lx, %E and %F for %le & %lf (these
were buggy anyway, since they should have represented %Le & %Lf).
- %[unknown uppercase char] for %ld, %[unknown lowercase char] for %d
Satoshi NIIMI-san kindly explained that EUC does not limit the byte length to
any arbitrary number.
We now set the limit to the maximum octet length of the codeset and it is
locale-specific.

and add some compatibility defines. Add fields for ins and locals to
struct reg also for the same reason; these aren't filled in yet because
getting at those registers sucks and I'd rather not save them in the
trapframe just for this. Reorder struct reg to be ABI compatible as
well. Add needed include of machine/emul.h.
This gets pmdb (poor man's debugger) from OpenBSD mostly compiling but it
