Summary:
This will make it easier to incrementally migrate APIs to async, and make sync
programs able to use sync interface if they'd like to. For example, the dag
crate is likely going to be async-ize. Its async APIs are only useful for
places where the dag is lazy. It's still possible to have a non-lazy dag
that a sync interface is suitable.

Summary:
The f64 compatibility added by D25079001 (e91552fefe) changes the `{rev}` template output.
However, the revset object is not aware of the rev mapping so the following
pattern will stop working:
ifcontains(rev, revset('.'), '@', 'o')
# rev: mapped, but not contains in `revset('.')`
Fix it by teaching `ifcontains(a, b, ...)` to disable f64 compatibility when
evaluating `a`, since `a` is not going to be printed out.
This fixes an issue in VSCode ISL that "You are here" is missing on non-master

Summary:
Introduce `edenapithin` crate, which offers C bindings to EdenAPI Client.
There are two top-level `owned` types, `EdenApiClient` and `TreeEntryFetch`, which represent `Box`ed results from calls to EdenAPI's blocking client. The C / C++ code is responsible for calling the associated `free` functions for these types, as well as `OwnedString`, which is used to represent error variants of a `Result` as a string.
Most functionality is provided through functions which operate on and return references into these top-level owned types, providing access into Rust `Result`s and `Vec`s (manually-monomorphized), and EdenApi's `TreeEntry` and `TreeChildEntry`.
Additional non-pointer types are defined in the `types` module, which do not require manual memory management.
C++ bindings are not included currently, but will be introduced soon.

succeed, given Mononoke knows about this filenode:

```
Turns out, the success rate for this method is actually 0% — out of thousands of requests,
not a single one succeeded :(
https://fburl.com/scuba/edenapi_server/cma3c3j0
The root cause here is that the server side is not properly deserializing
requests (actually finding that was a problem of its own, I filed T80406893 for this).
If you manage to get it to print the errors, it says:
```
{"message":"Deserialization failed: missing field `path`","request_id":"f97e2c7c-a432-4696-9a4e-538ed0db0418"}
```
The reason for this is that the server side tries to deserialize the request
as if it was a `WireHistoryRequest`, but actually it's a `HistoryRequest`, so
all the fields have different names (we use numbers in `WireHistoryRequest`).
This diff fixes that. I also introduced a helper method to make this a little
less footgun-y and double-checked the other callsites. There is one callsite
right now that looks like it might be broken (the commit one), but I couldn't
find the client side interface for this (I'm guessing it's not implemented
yet), so for now I left it as-is.

The `getdesignatednodes` function returns a boolean indicating whether the requested nodes were actually fetched.
In the case of SSH, this is needed because the server may not support the `designatednodes` capability (only supported by Mononoke). If the fetch fails, Mercurial will fall back to an expensive complete tree fetch.
The HTTP version of this function accidentally omitted `return True`, which meant it implicitly returned `None`, which triggered the fallback path.
