[krbdev.mit.edu #1432] patch to compile with cygwin

["Christopher B. Liebman" via RT]

There are two issues that this patch fixes:

1)  Cygwin implements error as a function that returns an int.  There are
locations in krb5 that declare errno as "extern int errno" the patch
includes errno.h instead.  Maybe a better fix is to have configure look to
see if errno.h exists and include it?

2) Cygwin has the same issues as Windows/DOS with renaming a file while it's
still open.  This patch uses almost exactly the same code to fix this issue
manifesting in the replay cache code.
