Also, I've added handling for other mod_exp calls that were not using any
cached montgomery forms. These cases matter only for special RSA keys (eg.
ones that are missing information) so are unlikely to be used in normal
circumstances.
verification step of CRT private key operations in the RSA code -
previously no montgomery form was checked or used for 'n', and so it would
be generated on the fly each time. As a result, private key operations are
now a percent or two faster.
Rather than adding this as another repetition of the nearly-identical
montgomery "check for first-use" initialisation code blocks, I've taken
this chance to create a helper function and macro-wrapper to replace them.

applications, at least on the platforms where it's known how
to do it.
Note: this has only been tested on GNU-based platforms (Linux), and
needs to be tested on all others. Additionally, it's not yet
supported on the following platforms, for lack of information:
Darwin (MacOS X)
Cygwin
OSF1/Alpha
SVR3
ReliantUNIX
Please help out with testing and the platforms we don't yet know well
enough.
efficiency (EC_PRE_COMP objects are now constant once completed).
Extend 'extra_data' API to support arbitrarily many slots (although we
need only one at the moment).
Modify EC internal 'extra_data' API: EC_GROUP_[clear_]free_extra_data
now frees only a single slot (the previous functions are available as
EC_GROUP_[clear_]free_all_extra_data).

the header files where the problem existed include ossl_typ.h, which makes
a 'forward declaration' of the ENGINE type.

this code unless OPENSSL_USE_GMP is defined (because it will impose header
