Coverity complains about the leakage of 'handle' when the identifier
goes out of scope. Change handle into a static global to hold the
value instead of a stack variable.

This adds a new backend for libhcrypto: the OpenSSL backend.
Now libhcrypto has these backends:
- hcrypto itself (i.e., the algorithms coded in lib/hcrypto)
- Common Crypto (OS X)
- PKCS#11 (specifically for Solaris, but not Solaris-specific)
- Windows CNG (Windows)
- OpenSSL (generic)
The ./configure --with-openssl=... option no longer disables the use of
hcrypto. Instead it enables the use of OpenSSL as a (and the default)
backend in libhcrypto. The libhcrypto framework is now always used.
OpenSSL should no longer be used directly within Heimdal, except in the
OpenSSL hcrypto backend itself, and files where elliptic curve (EC)
crypto is needed.
Because libhcrypto's EC support is incomplete, we can only use OpenSSL
for EC. Currently that means separating all EC-using code so that it
does not use hcrypto, thus the libhx509/hxtool and PKINIT EC code has
been moved out of the files it used to be in.
All source files in lib/hcrypto should be built the same way.
Since this source directory is dependent on libroken then all source
files must be built using the roken.h declarations and included headers.
Also, there is no config.h in the local directory so angle brackets
include of quotes should be used.
Finally, because roken.h includes stdio.h, stdlib.h, stdarg.h, limits.h,
strings.h, sys/types.h, etc., do not include them separately.
Start all source files with
#include <config.h>
#include <roken.h>

The build was failing at lib/hcrypto/evp-pkcs11.c because roken.h was
being included after <assert.h>. It's not clear why that would be a
problem.
Here are some of the errors and warnings that resulted from including
<roken.h> after <assert.h> in evp-pkcs11.c:
