Seems like this restriction was actual when Ziglang had extern enums,
but now it's not neccessary and can be lifted. It was present since
original PR which introduced std.enums, https://www.github.com/ziglang/zig/pull/8171.

* Make `count` comptime_int instead of usize
With previous type, creating EnumIndexer for enum(usize) and enum(isize)
would cause compile error since `count` could not store maxInt(usize) + 1.
Now it can store it and reflects len field from std.builtin.Type.Array
(most common use case of count field inside std.enums functions is creating arrays).

This change fixes some division-by-zero bugs introduced by the optimized
ring buffer read/write functions in d8c067966.
There are edge cases where decompression can use a length zero ring
buffer as the size of the ring buffer used is exactly the the window
size specified by a Zstandard frame, and this can be zero. Switching
away from loops to mem copies means that we need to ensure ring buffers
do not have length zero ring when attempting to read/write from them.
There is no grantee that `copy_cqes` will return exactly wait_nr number of cqes.
If there are ready cqes it can return > 0 but < wait_nr number of cqes.
The low-level `Curve25519.fromEdwards25519()` function assumed
that the X/Y coordinates were not scaled (Z=1).
But this is not guaranteed to be the case.
In most real-world applications, the coordinates are freshly decoded,
either directly or via the `X25519.fromEd25519()` function, so this
is not an issue.
However, since we offer the ability to do that conversion after
arbitrary computations, the assertion was not correct.
Perform these transformations in this priority order:
1. If the `else` expression is missing or an empty block, replace the condition with `if (true)` if it is not already.
2. If the `then` block is empty, replace the condition with `if (false)` if it is not already.
3. If the condition is `if (true)`, replace the `if` expression with the contents of the `then` expression.
4. If the condition is `if (false)`, replace the `if` expression with the contents of the `else` expression.
Server networking application typically accept multiple connections. Multishot
accept simplifies handling these situations. Applications submits once and
receives CQE whenever a new connection request comes in.
Multishot is active until it is canceled or experience error. While active, and
further notification are expected CQE completion will have IORING_CQE_F_MORE set
in the flags. If this flag isn't set, the application must re-arm this request
by submitting a new one.
