In general, my plan is to duplicate and strip down k5-platform.h, and
include k5-platform.h and krb5.h instead of k5-int.h.  There are some
other entanglements to deal with:

  * krb5_read_message, krb5_write_message, and krb5_net_read are used in
various places and are not part of the API.  Simplest (though perhaps
not best) is to make them part of the API.

  * krcp uses krb5_set_config_files in some compatibility code; not sure
what that's about.

  * login.c dereferences the context to get the profile instead of using
krb5_get_profile.

  * kcmd.c uses data_eq_string.

Ideally I'd like to migrate the application tests to krb5-appl.  I
assume that would result in some amount of decreased code coverage from
the test suite, but I'm not sure how much.

Requiring a crazy build of krb5-appl to productively run the krb5 test
suite would not be a good end state.  If this turns into too much of a
blocker, I will just decide that "expand the code coverage of the krb5
test suite independent of the application tests" is a prerequisite for
unbundling the applications, which probably means pushing off
unbundingling until after 1.8.
