Add missing static keywords to uname(1)

Add new -o option (r203042) to manpage synopsis and usage().

Submitted by: ru

Allow -o as a synonym for -s, for compatibility with other systems.

Using -s is preferred, but some existing scripts and makefiles expect
to get the system name from uname -o.

Make the sysctlbyname stuff look like the 2-level MIB stuff. This
means actually setting 'len', for example. Which will make uname -i
work on some systems where it did not. Anywhere where it did work,
it was a matter of coincidence.

Submitted by: redpixel on EFnet.

Add sysctlbyname(3) support, and use that for uname -i, in preparation for
replacing the committed static OID version with a string-based OID_AUTO
version.

Make kernel identification (`ident' in the config(8) driver) available to
userland, and the kernel. In the kernel by way of the 'ident[]' variable
akin to all the other stuff generated by newvers.sh. In userland it is
available to sysctl consumers via KERN_IDENT or 'kern.ident'. It is exported
by uname(1) by the -i flag.

Use some macro evil to create the functions for using sysctl(3) to get each
variable natively. It should allow you to use any sysctl mib set, but due
to limitations of what I can do with macros, right now it's limited to two,
which is all this program used anyway.

Check to see if we should print a space, rather than using the annoying
prefix methodology. Adjust nearby style.

Mostly rewrite the flag handling of uname(1) to be overridable, such as:
freefall% uname -s
FreeBSD
freefall% env UNAME_s=Linnex ./uname -s
