libc. I want to keep these in some version for the thread
library/ies, but don't know whether to have them repo-copied
to libc_r or renamed and kept in libc.
Change the name of an alpha macro that was changed with the
system call commit.
Previously these were libc functions but were requested to
be made into system calls for atomicity and to coalesce what
might be two entrances into the kernel (signal mask setting
and floating point trap) into one.
A few style nits and comments from bde are also included.

subsystems capabilities:
_SC_AIO_LISTIO_MAX returns the default of _POSIX_AIO_LISTIO_MAX
_SC_AIO_MAX returns the default _POSIX_AIO_MAX
_SC_AIO_PRIO_DELTA_MAX returns the default of 0
Without these adjustments the values returned are -1 even when the
aio side of the kernel returns '0' for them which is incorrect.

No functional changes, but:
+ the mrouting module now should behave the same as the compiled-in
version (it did not before, some of the rsvp code was not loaded
properly);
+ netinet/ip_mroute.c is now truly optional;
+ removed some redundant/unused code;
+ changed many instances of '0' to NULL and INADDR_ANY as appropriate;
+ removed several static variables to make the code more SMP-friendly;
+ fixed some minor bugs in the mrouting code (mostly, incorrect return
values from functions).
This commit is also a prerequisite to the addition of support for PIM,
which i would like to put in before DP2 (it does not change any of
the existing APIs, anyways).
Note, in the process we found out that some device drivers fail to
properly handle changes in IFF_ALLMULTI, leading to interesting
behaviour when a multicast router is started. This bug is not
corrected by this commit, and will be fixed with a separate commit.
Detailed changes:
--------------------
netinet/ip_mroute.c all the above.
conf/files make ip_mroute.c optional
net/route.c fix mrt_ioctl hook
netinet/ip_input.c fix ip_mforward hook, move rsvp_input() here
together with other rsvp code, and a couple
of indentation fixes.
netinet/ip_output.c fix ip_mforward and ip_mcast_src hooks
netinet/ip_var.h rsvp function hooks
netinet/raw_ip.c hooks for mrouting and rsvp functions, plus
interface cleanup.
netinet/ip_mroute.h remove an unused and optional field from a struct
Most of the code is from Pavlin Radoslavov and the XORP project

the deprecated utime(3). utimes(2) uses timeval, but utime(3) uses
time_t's. If you do bad things (like I did) by mixing up include files
with libc, then install can do strange things if you mismatch the time_t
stuff. utime() is emulated entirely within libc.

time_t. Deal with the possibility that time_t != int32_t. This boils
down to this sort of thing:
- time(&ut.ut_time);
+ ut.ut_time = time(NULL);
and similar for ctime(3) etc. I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.

since there is no significant exposure in the syscall interface. The

more manageable.
- Add some helper variables (CVS_{SRC,DOC,PORTS}ARGS) to be used when
using CVS to checkout files. We stick release tags in these helper
variables if they are defined and then use only one cvs command instead
of two cvs commands with an .ifdef to choose between them.
- rm the old src/doc/ports directories as separate commands from the
CVS comands so that the rm commands don't need to be duplicated.
- Simplify the DOMINIMALDOCPORTS case by overriding RELEASEPORTSMODULE to
be ${MINIMALDOCPORTS} thus removing yet another nearly-duplicate cvs
command in an .ifdef.
- Add support for grabbing src/ and doc/ from external directories
specified via EXTSRCDIR and EXTDOCDIR instead of from CVS. The same
is not done for ports/ quite yet as the DOMINIMALDOCPORTS case is a
bit tricky.
The rerelease target scripts have not been changed to use the helper
variables yet, so there is still some room for improvement.

works on sparc64, this document can now use (almost) the same
procedures as i386, et al. CDROM booting instructions are cut-and-pasted
from the older sparc64/install.sgml file, which is now unlinked from
the document build.
This document is a long ways from perfect, but it's better than shipping
instructions for an installation procedure that doesn't apply anymore.
While here, add some SGML comments to help others navigate the sources.
descriptors that have the close-on-exec flag set, as that will have no
effect anyway and might screw something else up if the file descriptor
happens to be shared with another process.
