8254c3c5d3 Fix C++ includability of crypto headers with static array sizes
C99 allows array function parameters to use the static keyword for their
sizes. This tells the compiler that the parameter will have at least the
specified size, and calling code will fail to compile if that guarantee is
not met. However, this syntax is not legal in C++.

This commit reverts r300824, which worked around the problem for
sys/sys/md5.h only, and introduces a new macro: min_size(). min_size(x) can
be used in headers as a static array size, but will still compile in C++
mode.

571ebf7685 crypto routines: Hint minimum buffer sizes to the compiler
Use the C99 'static' keyword to hint to the compiler IVs and output digest
sizes.  The keyword informs the compiler of the minimum valid size for a given
array.  Obviously not every pointer can be validated (i.e., the compiler can
produce false negative but not false positive reports).

No functional change.  No ABI change.

2155bb238f Break up opencrypto/xform.c so it can be reused piecemeal
Keep xform.c as a meta-file including the broken out bits
existing code that includes xform.c continues to work as normal

Individual algorithms can now be reused elsewhere, including outside
of the kernel

f7d7fca7fd Prototype fix for IPsec authentication related functions
Some of IPsec authentication related functions should have
  'const' for its 2nd argument, but not now.
  But if someone try to use them, and passed const data for
  those functions, then much bogus compile warnings will be
  generated.
  So those funcs prototype should be modified.

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.
