they cannot mount a filesystem that they cannot see in getvfsbyname().
Part 1 of this is a hack, make vfsisloadable() always return true - the
ultimate decider of whether it's loadable or not is kldload() or mount().
Part 2 of this is to have vfsload() call kldload(2) and return success if
it works. This means that we will use a viable kld module in preference
to an LKM!
Ultimately, the thing to do is remove the hacks to do a vfsload in all the
mount_* commands and let the kernel do it by itself in mount(2).
vfork() can't be used. We could use alloca() in execl() so that
it can be called between vfork() and execve(), but a "portable"
popen() shouldn't depend on this. Calling execle() instead of
execl() should be fairly safe, since execle() is supposed to be
callable from signal handlers and signal handlers can't call
malloc(). However, execle() is broken.

The scandir() function returns -1 if it fails.
In many cases when this happens, it does not free
the memory that it allocated, resulting in a memory
leak, or close the directory opened with opendir().
BAD DOG, BAD!
In some cases replace if (a == null) a = malloc(x); else a =
realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is
guaranteed to be the same thing.
I've been running these on my system here w/o ill effects for some
time. However, the CTM-express is at part 6 of 34 for the CAM
changes, so I've not been able to do a build world with the CAM in the
tree with these changes. Shouldn't impact anything, but...
addresses by default.
Add a knob "icmp_bmcastecho" to "rc.network" to allow this
behaviour to be controlled from "rc.conf".
Document the controlling sysctl variable "net.inet.icmp.bmcastecho"
in sysctl(3).

- Fix some style errors I made back in 1995.
- Add a new flavor of the err(3) family, which takes an explicit
errno argument rather than implicitly examining errno. This
will make it easier to use these functions in conjunction with
modern library interfaces that return an errno value explicitly.
standard places ("/etc/objformat", ${OBJFORMAT}, argv) for an
indication of the user's preferred object file format. This
consolidates some code that was starting to be duplicated in more
and more places.
Use the new function in ldconfig.
Note: I don't think that gcc should use getobjformat(), even though
it could. The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.
revisions to match the confusing spelling in getttyent.c (1 to
break it to match the man page and 1 in each of 2 branches to fix
it). This function seems to be orphaned and unused.
copy to bring these files into libc from libcompat. I will enable
them and kill off the libcompat versions on the main branch soon.

Return the result from getpagesize() if the p1003_1b.pagesize MIB
value is zero.
