Some applications write a profile file and then immediately use it via
a krb5_context.  If we have a cached copy of the profile we wrote,
make sure to update it by forcing a stat when we reuse an existing
prf_data_t object.

Replace util_ordering.c with a new file util_seqstate.c, implemented
using a bitmap of previously received sequence numbers instead of a
20-element circular queue.  This approach has slightly different
limitations--it can check for replays for values within 64 of the
expected next number, where the old code could check within the range
of the last 20 received numbers regardless of how far apart they are.
The new approach should work as well or better for any realistic
packet reordering scenario.

Use an opaque structure type instead of a void pointer for the
sequence number state.  Rename all functions to use a g_seqstate
prefix rather than a mix of g_order and g_queue.  Remove the
unneccessary indirection from the state object parameter in
g_seqstate_check and g_seqstate_free.  Return OM_uint32 where we
return a GSS major code, long where we return an errno value, and void
where we can't fail.

Since we no longer prefix an "#include <stdint.h>" in the gssapi.h
preamble at build time, include it in gssapi.hin.

Update util/gss/kernel-lib/Makefile.in to account for gssapi_krb5.h
being in the source tree.

Directly use stdint.h names for integer types in preference to the
various internal names we have made up for them.

Make unconditional use of <stdint.h> and fixed-width types such as
uint32_t.  k5-plugin.h doesn't use any special integer types, so
remove the conditional include block there.  Nothing uses
INT64_FMT/UINT64_FMT, so leave those out of k5-platform.h for now.

Remove the GNATS-based krb5-send-pr script and replace it with a
script that instructs users to send email.

r17942 added a call to get_thread_buffer in the first part of
error_message, prior to the call to com_err_initialize.  This can
cause an assertion failure from k5_getspecific if error_message is
called on a system error before any other com_err functions are
called.  Move the initialization call earlier to prevent this.

$(BUILDTOP)/include/profile.h was being updated by two different
rules, which could collide with make -j.  Use a dependency from
includes instead of a redundant rule.
