Together these two implement a simple transcation style grouping for
modifications of extended attributes on a vnode.
VOP_CLOSEEXTATTR() takes a boolean "commit" argument, which determines
if the aggregate changes are attempted written or not. A commit will
fail if any of the VOP_SETEXTATTR() calls since the VOP_OPENEXTATTR()
have failed to meet their objective or if the flush to disk fails.
The default operations for these two VOP's is to return EOPNOTSUPP.
This API may still be subject to change.

- use `struct uma_zone *' instead of uma_zone_t, so that <sys/uma.h> isn't
a prerequisite.
- don't include <sys/uma.h>.
Namespace pollution makes "opaque" types like uma_zone_t perfectly
non-opaque. Such types should never be used (see style(9)).
Fixed subsequently grwon dependencies of this header on its own pollution:
- include <sys/_mutex.h> and its prerequisite <sys/_lock.h> instead of
depending on namespace pollution 2 layers deep in <sys/uma.h>.
not the 'entry' member. The entry point is formed from both a base and
a relative entry point. 'entry' is that relative offset. It is perfectly
valid to have an entry point with a relative offset of 0. PCIbios.ventry
is the virtual address of the entry point that takes both 'base' and
'entry' into account, thus it is the proper variable to test to see if we
have an entry point or not.
1) Include arpa/inet.h for ntohs.
2) Constness fixes.
3) Fix shadowing except for "sin" which shouldn't be in scope.
4) Remove register keyword.
5) Add missing initialsers to user defined structs.
5) Make prototype of netname6 globally visable.
6) Use right macros for printing syncache stats (even though entrie isn't
a word).
lnc(4) will attach to AMD PCnet/FAST NICs if pcn(4) does not attach.
I.e. pcn(4) gets first chance. There is a problem however in that pcn(4)
was moved out of the install kernel so that the module would be used.
This however causes bad installs if one has an AMD PCnet/FAST NIC.

Include <sys/vmmeter.h> instead of depending on namespace pollution in

Sorted includes as much as possible.
my previous commit, so the commit message is incorrect for them.
The actual changes were:
elfcore.c 1.11:
Use a uintmax_t 'cos we con't know if php->p_filesz will be a
Elf32_Size or an Elf64_Size and we don't know how these relate to
size_t. Change some ints to size_t and ssize_ts.
gcore.c 1.28:
Include <arpa/inet.h> for ntohl, which is used in N_BADMAG.
Use a uid_t for a uid.
md-nop.c 1.6:
Mark some parameters as unused.
s/SNGL/SINGLE/
s/SNGLE/SINGLE/
Fix abbreviation for P_STOPPED_* etc flags, in original code they were
inconsistent and difficult to distinguish between them.

layers deep in <sys/proc.h> or <sys/vnode.h>.
Removed unused includes.
Fixed some printf format errors (1 fatal on i386's; 1 fatal on alphas;
1 not fatal on any supported machine).
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

While I'm here, add a the ability to say "!level" in a way which
should be compatible with Linux's syslogd.

This is a vast improvement over the i8254, since it is a simple
memory load rather than a comples sequence of interrupt blocking,
multiple input/output instructions, and wrap-around detection.
I have not bothered to time the fundamental timecounter get routine,
but gettimeofday(2) is 10% faster with the ELAN timecounte.
The downside is that HZ=100 is not enough, 150 or more recommended,
I use 250 myself.
