ff: Add PrimeField::ReprEndianness associated type
...
This enables generic code to reliably operate on the bits of an encoded
field element, by converting them to and from a known (little)
endianness.
The BitAnd and Shr bounds on PrimeField are now removed, as users can
perform these operations themselves as needed.

ff: Remove frobenius_map from Field trait
...
It is only used internally in the bls12_381 crate, and field extensions
aren't exposed anywhere in the Zcash stack.

ff: Remove SqrtField trait
...
The sqrt() function is now part of the Field trait. ff_derive returns an
error on fields for which it does not support generating a square root
function.
Note that Fq6 and Fq12 in pairing::bls12_381 leave the function
unimplemented. They will be dropped once the migration to the bls12_381
crate is complete. The equivalent structs in that crate are not exposed.

ff: Remove PrimeFieldRepr trait
...
The ff::PrimeField::Repr associated type now has the minimal necessary
bounds, which can be satisfied by a newtype around a byte array.

...
The trait is implemented by default for u8 and u64, allowing pow_vartime
to be used with both the byte encoding and limb representation of field
elements.
