* add more abosolutes
* added wrong files
* adding 2 tests and changing the function signatures because of lazy analysis not checking them
* fix a bug that got uncovered by lazy eval
* Add compile error when using WASI with openDirAbsolute and accessAbsolute
* typo
Transforming scalars to non-adjacent form shrinks the number of
precomputations down to 8, while still processing 4 bits at a time.
However, real-world benchmarks show that the transform is only
really useful with large precomputation tables and for batch
signature verification. So, do it for batch verification only.

This is quite an important feature to have since many other standards
being worked on depend on this operation.
Brings a couple useful arithmetic operations on field elements by the way.
This PR also adds comments to the functions we expose in 25519/field
so that they can appear in the generated documentation.
Make the code used to calculate the variable slot index into the frame
match what's done during the structure layout calculation.
Prevents a few nasty LLVM errors when such types are passed around.
See ziglang/fetch-them-macos-headers#2 for more details. The path
forward looks like one of the following:
* Ony provide headers for the oldest supported macOS (currently 10.13
but soon to be bumped to 10.14).
* Provide headers for multiple versions, and select based on the Zig
target OS version range minimum.
* Don't try to provide macOS headers.
If we don't tackle the version problem, we would have to re-introduce
the ability to detect and depend on native system headers if we wanted
to support C/C++ code that used newer OS definitions.
This patch also adds support for `#include <mach/mach_time.h>`.

CMake: Fix dependency problem
I don't know whether the error was expected cmake behavior or a bug.
This change seems to fix the issue. See ziglang#6724 for details.
We currently have ciphers optimized for performance, for
compatibility, for size and for specific CPUs.
However we lack a class of ciphers that is becoming increasingly
important, as Zig is being used for embedded systems, but also as
hardware-level side channels keep being found on (Intel) CPUs.
Here is ISAPv2, a construction specifically designed for resilience
against leakage and fault attacks.
ISAPv2 is obviously not optimized for performance, but can be an
option for highly sensitive data, when the runtime environment cannot
be trusted.
