Move (BSD-licensed) mkstemp from libdb2 to libkrb5support, and rename
the function to krb5int_mkstemp. Generate the symbol export list for
libkrb5support at build time.
Declare krb5int_mkstemp in k5-platform.h.
Change cc_file.c to use mkstemp unconditionally.
Make libdb2.so (built for testing only) link against the
libkrb5support, and use krb5int_mkstemp if mkstemp is not available.
