Move OTP sockets to KDCRUN_DIR

I have a slight preference for KDC_RUNDIR, but I haven't looked at prevailing practices for this naming convention.

[greghudson]

My preference is KDC_RUN_DIR.

The documentation needs to be updated. To do this, we will need a new substitution in src/doc/Makefile.in and doc/conf.py.

On IRC, Nathaniel noted that this changes the default socket directory with no fallback, and that runtime fallback code would be difficult. I think I am okay with that, but we will need a 1.13 release note about it.

[npmccallum]

I just pushed a new version which should address these issues.

[npmccallum]

I should mention that while this changes the default socket directory with no fallback, configured token types that specify a socket path will not be affected by this change. This only applies to the implicitly defined sockets. I am probably the only person using this.

[npmccallum]

I just made one more push. This change is to src/Makefile.in so that make install will create KDC_RUN_DIR. Doing this ensures that, in package managers, this directory is properly owned by the KDC.

[greghudson]

I think src/man/Makefile.in and doc/mitK5defaults.rst also need to be updated.

[greghudson]

Also, while I see support for the new substitution, I don't see anything actually using it; otp.rst is unchanged and still references $KDCDIR (which is an odd kind of shorthand since it's not an environment variable and $ substitutions don't work in that context).

[npmccallum]

That push fixes src/man/Makefile.in and doc/mitK5defaults.rst. I'm not quite sure what I should do in otp.rst. Hints are welcome.

[npmccallum]

This version adds support for proper substitution to otp.rst.

[greghudson]

I wasn't specific enough when I said mitK5defaults.rst needed to be updated; the part I meant was the table giving defaults for BINDIR/LIBDIR/etc.. Otherwise if you follow the link from RUNSTATEDIR in otp.html, you just see a table which says nothing about RUNSTATEDIR.

[npmccallum]

Does that solve the problem?

[npmccallum]

This commit moves /var/run to /run. This is because the Linux world has standardized on the latter.

[greghudson]

In the mitK5defaults.rst table, use "Parent of KDC runtime dir" to avoid overrunning the column width and having to extend the column.

In otp.rst, use |kdcrundir|\ /<name>.socket for the default socket path to get correct formatting.

[npmccallum]

Fixed.

Pushed to master with small changes to otp.rst.
