(symlink or hardlink) is already set. Instead, it was always setting
the hardlink field. In particular, this caused GNU tar format long
symlinks to be interpreted as hardlinks.

- Use /*- instead of /* for copyright section
- Include unistd.h for prototype of it
- Sort and separate includes as described in style(9)
- ANSIfy the function defination
- Use const for the traversing iterator
Have pmcstat(8) and pmccontrol(8) use these APIs.
Return PMC class-related constants (PMC widths and capabilities)
with the OP GETCPUINFO call leaving OP PMCINFO to return only the
dynamic information associated with a PMC (i.e., whether enabled,
owner pid, reload count etc.).
Allow pmc_read() (i.e., OPS PMCRW) on active self-attached PMCs to
get upto-date values from hardware since we can guarantee that the
hardware is running the correct PMC at the time of the call.
Bug fixes:
- (x86 class processors) Fix a bug that prevented an RDPMC
instruction from being recognized as permitted till after the
attached process had context switched out and back in again after
a pmc_start() call.
Tighten the rules for using RDPMC class instructions: a GETMSR
OP is now allowed only after an OP ATTACH has been done by the
PMC's owner to itself. OP GETMSR is not allowed for PMCs that
track descendants, for PMCs attached to processes other than
their owner processes.
- (P4/HTT processors only) Fix a bug that caused the MI and MD
layers to get out of sync. Add a new MD operation 'get_config()'
as part of this fix.
- Allow multiple system-mode PMCs at the same row-index but on
different CPUs to be allocated.
- Reject allocation of an administratively disabled PMC.
Misc. code cleanups and refactoring. Improve a few comments.
any query.
- don't query against IPv6 link-local address.
- use IN6_IS_ADDR_V4{MAPPED,COMPAT} macros.
- use memcpy() instead of bcopy().

These are two of the three files that have non-trivial differences from
the vendor branch. minigzip.c is the third, but there were no changes
from ZLib 1.2.1 to ZLib 1.2.2 in that file.
The rest of the files I intend to get reverted back to the vendor
branch (with cooperation of cvsadmin@).
PR: i386/76294
internal error if pax extended attributes were being generated. Being
< 255 characters, the first-pass path editing (to generate a
ustar-compatible name for the main entry) wouldn't occur, and the
second-pass path editing (to generate a ustar name for the pax
attributes entry) assumed the input was already < 245 chars.
The core problem here was using an abbreviated algorithm for the
second pass that relied on the first pass having already run. The
rewritten code is much simpler: It just uses the full path-shortening
algorithm for building both ustar pathnames. This way, the second
ustar pathname will always be short enough.
