This is a first sweep of reducing the number of terribly named macros
in bn.h More can go away. Those we need internally go to bn_local.h.
Annoyingly bn_internal.h uses some of them, so it includes bn_local.h
now. This can be cleaned up later.

Provide constant time conditional selection between EC_FIELD_ELEMENTs.2025-08-02T15:44:09+00:00jsing2025-08-02T15:44:09+00:00urn:sha1:1c7727d98f4279760cde2908bbfe7e06b323c209
Provide a ec_field_element_select() function that allows for constant time
conditional selection between two EC_FIELD_ELEMENTs. This will become a
building block for constant time point multiplication.

Implement EC field element operations.2025-05-25T05:12:05+00:00jsing2025-05-25T05:12:05+00:00urn:sha1:2f7bf75477a5741ad76c3c793c7ed887b41fcceb
Provide EC_FIELD_ELEMENT and EC_FIELD_MODULUS, which allow for operations
on fixed width fields in constant time. These can in turn be used to
implement Elliptic Curve cryptography for prime fields, without needing
to use BN. This will improve the code, reduces timing leaks and enable
further optimisation.
