Elliptic curve tower-cycle for Curve25519

Some advanced cryptographic protocols require a "curve cycle", which is a pair of elliptic curves Ep and Eq over prime fields GF(p) and GF(q) such that #Ep = q and #Eq = p, i.e. the scalar field of each curve exactly equals to the base field of the other curve.

Unfortunately, Curve25519 has a composite order (divisible by 8), so it cannot be part of a curve cycle (both p and q need to be primes).

However, if we could find a curve cycle with p = 2^255 - 19, points on Curve25519 could enter the cycle via curve Eq, which has an order of p. We call this arrangement a "tower-cycle":

	iOS 16 introduced launch constraints, which can be used to constraint the launch of an application.
	There are three types of constraints:
	Self Constraints, which the launched application itself must meet
	Parent Constraints, which the parent process must meet
	Responsible Constraints, which the "responsible process" must meet (I assume that the responsible process is the process that asked launchd to launch a service)

	Additionally, the TrustCache format was updated (see below) to support assigning each binary a "Constraint Category", which forces Self and Parent Constraints.
	Note that Self, Parent and Responsible Constraints can also be set by the process performing the launch and they can be included in the code signature, in the new blob type 0xFADE8181. In both cases, the constraints are DER encoded (just like the DER entitlements).

	Constraint Categories (from TrustCache, new in version 2):
