moved them to unistd.h to match POSIX in 1995 but we never did.
The exception to this is getsubopt() which POSIX says should be in
stdlib.h.  The non-standard suboptarg extern remains in the BSD-only
section of stdlib.h.  Neither getsubopt() nor suboptarg belong in
unistd.h or getopt.h.  They were only there to allow us to protect
all the getopt() bits from being multiply defined.  OK guenther@

EAGAIN causes spinning.
fix from claudio:
"Let msgbuf_write return -1 with errno EAGAIN. The users then must
check if this was the case and readd the event or poll again.  The
current handling in the imsg code is wrong for sure."

Committing now to unbreak ports builds (gvfs fails without, which knocks
out building much of the tree.)

note that on boards without ahci you will need to install to usb and still
boot of sd, at least until there's support for the sd slot.

Instead of running mkuboot during install, we call it on during
the release build, so that we can also ship bootable images
of the generic and the ramdisk kernel.
We can now build miniroots for imx, too.  The installer also
can recognize the SoC and makes decision based on it.
Use ext2fs for i.MX6 based devices.
Tar the bootloader files to save some space.

Bump libstdc++ major to be sure there isn't ABI issues.

- convert netstat from kvm_getfiles() to kvm_getfile2() using that
- delete kvm_getfiles() and KERN_FILE as no longer used (bump libkvm's major)
- rename kvm_getfile2() to kvm_getfiles(), kinfo_file2 to kinfo_file
and KERN_FILE2 to KERN_FILE.

at these pages and get caught up.

NB: this utility has only one option, and it's not optional! i haven;t
marked -s as being mandatory, since hopefully someone will make
ntpctl run without arguments do something useful;

* For time_t values, use the printf("%lld", (long long)t) idiom.
* Don't print "Invalid program name" in usage() when main() just runs ntpd.
* Make "Show/Shows" consistent in the manual, sort .Xr and correct .Ox.
