unix_seed(), called by the add-seed-data op unix_add(), attempts to
write seed data to the random data device. If this fails, the failure
is ignored, as it must be, since there is no way to inform the caller.
This change modifies the way in which the return value from write(2)
is ignored, to avoid compiler warnings when building on Ubuntu 12.10,
with gcc 4.7.2 and eglibc 2.15-0ubuntu20.1.
md2.c was doing memset(m, 0, sizeof(m)), and so was only clearing
the first 4 bytes of the passed md2 structure in MD2_Final. Fix
this to clear the entire structure, as expected.
Heimdal can be executed in environments in which the user
account profile is not loaded. In such environments it is
not possible to use PROV_RSA_FULL as it stores required
data within the profile. Instead, fallback to PROV_RNG which
does not store data within the profile and can be used to access
secure random number generator routines.

on a big endian machine, usage of this file in the kernel
is somewhat troublesome since the linux kernel already has
a well known global/#define called current.

most of these warnings are not problems because of ample
use of abort() calls. However, the large number of warnings
makes it difficult to identify real problems. Initialize
the variables to shut up the compilers.

hcrypto: struct x64 doesn't need bitfields
The bitfield specifications on the struct x64 members do not actually do
anything to guarantee/force packing or endian of the members. Removing
them allows the code to compile on certain compilers that do not support
bitfields on 64-bit types.

When using 64bit constants for initialisation flag them as LL, so
the compiler doesn't try to cast them down to a long, and throw away
information, on 32 bit platforms.

EVP_BytesToKey uses min() on a mixture of signed and unsigned
paramters. To avoid compiler warnings, use unsigned int for all
of the iv and key lengths in this function.
