V8's JIT can do a better job knowing the argument count and also enable
fast call path (in future).
This also lets us call async ops without `opAsync`:
```js
const { ops } = Deno.core;
await ops.op_void_async();
```
this patch: 4405286 ops/sec
main: 3508771 ops/sec
When an op returns an `anyhow` error with a cause (usually added using
the `.context()` method), the `Error` thrown into JavaScript contains
only the message of the outernmost error in the chain.
This PR simply changes the formatting of `anyhow::Error` from `"{}"` to
`"{:#}"`:
This significantly improves errors for code that embeds Deno and defines
custom ops. For example, in
[chiselstrike/chiselstrike](https://github.com/chiselstrike/chiselstrike),
this PR improves an error message like
```
Error: could not plan migration
```
to
```
Error: could not plan migration: could not migrate table for entity "E": could not add column for field "title": the field does not have a default value
```
This commit stabilizes "Deno.consoleSize()" API.
There is one change compared to previous unstable API,
in that the API doesn't accept any arguments. Console size
is established by querying syscalls for stdio streams at fd
0, 1 and 2.
Previously `op_net_listen`, `op_net_accept`, and various other ops in
ext/net where variadic on the transport. This created a lot of code
bloat. This commit updates the code to instead have separate ops for
each transport.
This commit adds a `reuseAddress` option for UDP sockets. When this
option is enabled, one can listen on an address even though it is
already being listened on from a different process or thread. The new
socket will steal the address from the existing socket.
On Windows and Linux this uses the `SO_REUSEADDR` option, while on other
Unixes this is done with `SO_REUSEPORT`.
This behavior aligns with what libuv does.
TCP sockets still unconditionally set the `SO_REUSEADDR` flag - this
behavior matches Node.js and Go. This PR does not change this behaviour.

When listening on a UNIX socket path, Deno currently tries to unlink
this path prior to actually listening. The implementation of this
behaviour is VERY racy, involves 2 additional syscalls, and does not
match the behaviour of any other runtime (Node.js, Go, Rust, etc).
This commit removes this behaviour. If a user wants to listen on an
existing socket, they must now unlink the file themselves prior to
listening.
This change in behaviour only impacts --unstable APIs, so it is not
a breaking change.
This PR fixes a regression that caused deno binaries produced by the CI
release workflows to be larger than expected.
**The problem:** The build script will determine whether the linker
supports the `--export-dynamic-symbol-list` flag by looking at the glibc
version installed on the system. Ubuntu 20.04 ships with glibc 2.31,
which does not support this flag. Upon investigation, I discovered that
the CI pipeline does not use the gcc compiler provided by the
`build-essential` package, and instead uses *clang-14*, which does
support the new flag.
**The solution:** Whenever a custom C Compiler is configured, the build
script now assumes the compiler supports the
`--export-dynamic-symbol-list` flag. This is not always going to be the
case (you could use clang-8, for example), but it puts the onus on the
user making the override to ensure the compiler has support.
This will return deno builds for Linux to their previous size of ~100MB,
and also allow builds under older glibc/gcc versions to succeed. If a
user is compiling deno with a custom compiler that does not support this
new flag, however, their build will fail. I expect this is a rare
scenario, however, and suggest we cross that bridge if and when we come
to it.
