callbacks, entering FIPS mode etc.

Test mode is now set when a DRBG context is initialised.

different options:
"64"		The build system will choose /POINTER_SIZE=64=ARGV if
		the compiler supports it, otherwise /POINTER_SIZE=64.
"64="		The build system will force /POINTER_SIZE=64.
"64=ARGV"	The build system will force /POINTER_SIZE=64=ARGV.

  Have EC_NISTP224_64_GCC_128 treated like any algorithm, and have
  disabled by default.  If we don't do it this way, it screws up
  libeay.num.

  aren't trustworthy (see examples 13 and 14, they have the same mac,

  instead.

  messages (some of the test vectors have messages 65536 bytes long),
  and to handle cases where there are several keys (Three Key TDEA)

* fips/fips_test_suite.c, fips/fipsalgtest.pl, test/Makefile: Hook in
  test cases and build test program.

* fips/cmac/*: Implement the basis for FIPS CMAC, using FIPS HMAC as
  an example.
* crypto/cmac/cmac.c: Enable the FIPS API.  Change to use M_EVP macros
  where possible.
* crypto/evp/evp.h: (some of the macros get added with this change)
* fips/fips.h, fips/utl/fips_enc.c: Add a few needed functions and use
  macros to have cmac.c use these functions.
* Makefile.org, fips/Makefile, fips/fips.c: Hook it in.

This meant alarger renumbering in util/libeay.num due to symbols
appearing in 1.0.0-stable and 1.0.1-stable.  However, since there's
been no release on this branch yet, it should be harmless.

  more need to be added...

  with turning trapping back on.
* test/maketests.com: Do the same check for /POINTER_SIZE=64=ARGV
  here.
* test/clean-test.com: A new script for cleaning up.

  directly in main().  'if needed' also includes when argv is a 32 bit
  pointer in an otherwise 64 bit environment.
* apps/makeapps.com: When using /POINTER_SIZE=64, try to use the additional
  =ARGV, but only if it's supported.  Fortunately, DCL is very helpful
  telling us in this case.

include directory, as other parts (notably, EVP) seem to need it.
