Linking with lld fails as it contains a relative address, however the data
this address is for may be relocated from the shared object to the main
executable.
Fix this by adding the hidden attribute. This stops moving this value to
the main executable. It seems this is implicit upstream as it uses a
version script.

Change the calls to of blacklist_init() and blacklist_notify to be
macros defined in the blacklist_client.h file. This avoids
the need for #ifdef USE_BLACKLIST / #endif except in the
blacklist.c file.
Remove redundent initialization attempts from within
blacklist_notify - everything always goes through
blacklistd_init().
Added UseBlacklist option to sshd, which defaults to off.
To enable the functionality, use '-o UseBlacklist=yes' on
the command line, or uncomment in the sshd_config file.

We probably need some procedure to ensure that SHLIB_VERSION_NUMBER

If krb5_make_principal fails, tmp_creds.server may remain a pointer to freed

RFC 4402 specifies the implementation of the gss_pseudo_random()
function for the krb5 mechanism (and the C bindings therein).
The implementation uses a PRF+ function that concatenates the output
of individual krb5 pseudo-random operations produced with a counter
and seed. The original implementation of this function in Heimdal
incorrectly encoded the counter as a little-endian integer, but the
RFC specifies the counter encoding as big-endian. The implementation
initializes the counter to zero, so the first block of output (16 octets,
for the modern AES enctypes 17 and 18) is unchanged. (RFC 4402 specifies
that the counter should begin at 1, but both existing implementations
begin with zero and it looks like the standard will be re-issued, with
test vectors, to begin at zero.)
This is upstream's commit f85652af868e64811f2b32b815d4198e7f9017f6,
from 13 October, 2013:
% Fix krb5's gss_pseudo_random() (n is big-endian)
%
% The first enctype RFC3961 prf output length's bytes are correct because
% the little- and big-endian representations of unsigned zero are the
% same. The second block of output was wrong because the counter was not
% being encoded as big-endian.
%
% This change could break applications. But those applications would not
% have been interoperating with other implementations anyways (in
% particular: MIT's).
