The Cygwin/MinGW build now passes "make test".

It would incorrectly interpret retries as EOF, incorrectly

behaviour was not quite consistent with the conventions
for d2i and i2d functions as far as handling of the 'out'
or 'in' pointer is concerned.

This patch changes this behaviour, and renames the functions to
o2i_ECPublicKey and i2o_ECPublicKey (not 'd2i' and 'i2d' because the
external encoding is just a raw object string without any DER icing).

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.

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.
