79aa04ef27 Make the necessary changes to work with the recent "ex_data" overhaul.
See the commit log message for that for more information.

NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.

9c10b2c8d3 For consistency with the terminology used in my SAC2001 paper, avoid
the term "simultaneous multiplication" (which -- acording to the
paper, at least -- applies only to certain methods which we don't use
here)

1f0af2c073 len is a size_t, which is an unsigned integer. Therefore, some
compilers will complain against the check for less than zero.

8a2908a24a Since they aren't implemented yet, EC_GFp_{recp,nist}_method() need to

4f69172d25 Completely remove mont2 stuff.
It does not appear to be faster than the current Montgomery code
except for very small moduli (somewhere between 192 and 224 bits
in a 64-bit Sun environment, and even less than 192 bits
on 32 bit systems).

that applications can request precomputation when appropriate.

4e20b1a656 Instead of telling both 'make' and the user that ranlib
errors can be tolerated, hide the error from 'make'.
This gives shorter output both if ranlib fails and if
it works.

786e0c2424 EC_set_half and the 'h' component of struct bn_ec_struct are unnecessary.

7e0c5264e7 Elliptic curves over GF(p), new BIGNUM functions, Montgomery re-implementation.
These new files will not be included literally in OpenSSL, but I intend
to integrate most of their contents.  Most file names will change,
and when the integration is done, the superfluous files will be deleted.
