This commit adds "Deno.Conn.ref()" and "Deno.Conn.unref()" methods.
These methods can be used to make connection block or not block the
event loop from finishing. Refing/unrefing only influences "read"
operations - ie. scheduling writes to a connection _do_ keep event
loop alive.

This commit fixes handling of rejected promises in dynamic imports
evaluation.
Previously we were running callbacks for next ticks and macrotasks
_before_ polling
dynamic imports and checked for unhandled rejections immediately after.
This is wrong,
as `unhandledrejection` event is dispatched and its callbacks are run as
macrotasks.
This commit changes order of actions performed by the event loop to
following:
- poll async ops
- poll dynamic imports
- run next tick callbacks
- run macrotask callbacks
- check for unhandled promise rejections

This commit changes permission prompt to show that "import()" API
is requesting permissions.
Given "dynamic_import.js" like so:
```
import("https://deno.land/std@0.170.0/version.ts");
```
Before:
```
deno run dynamic_import.js
⚠️ ┌ Deno requests net access to "deno.land".
├ Run again with --allow-net to bypass this prompt.
└ Allow? [y/n] (y = yes, allow; n = no, deny) >
```
After:
```
deno run dynamic_import.js
⚠️ ┌ Deno requests net access to "deno.land".
├ Requested by `import()` API
├ Run again with --allow-net to bypass this prompt.
└ Allow? [y/n] (y = yes, allow; n = no, deny) >
```
This commit fixes formatting of JSError with "errors" property. Before this
commit all instances of "Error" were treated as if they were "AggregateError"
if they had "errors" property. After this commit only actual instances of
"AggregateError" are formatted in such a way, while instances of "Error"
that have "errors" property are formatted without showing details of "errors".
Although PR #16366 did not fully revert `deno_core`'s support for
realms, since `JsRealm` still existed after that, it did remove the
`ContextState` struct, originally introduced in #14734. This change made
`js_build_custom_error_cb`, among other properties, a per-runtime
callback, rather than per-realm, which cause a bug where errors thrown
from an op would always be constructed in the main realm, rather than in
the current one.
This change adds back `ContextState` to fix this bug, adds back the
`known_realms` field of `JsRuntimeState` (needed to be able to drop the
callback when snapshotting), and also relands #14750, which adds the
`js_realm_sync_ops` test for this bug that was removed in #16366.
Previously, errored streaming response bodies did not cause the HTTP
stream to be aborted. It instead caused the stream to be closed gracefully,
which had the result that the client could not detect the difference
between a successful response and an errored response.
This commit fixes the issue by aborting the stream on error.
This PR adds the concept of a global `DrawThread`, which can receive
multiple renderers to draw information on the screen (note: the
underlying thread is released back to tokio when it's not rendering). It
also separates the concept of progress bars from the existing "draw
thread". This makes it trivial for us to do stuff like show permission
prompts and progress bars at the same time in the future.
The reason this is global is because the process' tty stderr is also a
global concept.
Right now an error in a request body stream causes an uncatchable
global promise rejection. This PR fixes this to instead propagate the
error correctly into the promise returned from `fetch`.
It additionally fixes errored readable stream bodies being treated as
successfully completed bodies by Rust.
This commit refactors several things in "runtime/permissions" module:
- splits it into "mod.rs" and "prompter.rs"
- adds "PermissionPrompter" trait with two implementations:
* "TtyPrompter"
* "TestPrompter"
- adds "before" and "after" prompt callback which can be used to hide
progress bar in the CLI (to be done in a follow up)
- "permissions_prompt" API returns "PromptResponse" enum, instead
of a boolean; this allows to add "allow all"/"deny all" functionality
for the prompt
The output of `init` are commands, so this should be treated as a "Shell
script". In Shell script, comments must start with `#`, not `//`. (This
also makes the commands example easier to be copied to somewhere.)
This commit changes implementation of "Deno.memoryUsage()" to return
correct value for "rss" field. To do that we implement a specialized function
per os to retrieve this information.
- `JsRuntime::built_from_snapshot` was removed because it was redundant
with `JsRuntime::snapshot_options`.
- Updates to stale documentation of `JsRuntime::create_realm`.
- `JsRuntime::create_realm` now calls `JsRuntime::init_extension_js`
unconditionally, since if the runtime was built from a snapshot,
`init_extension_js` will be a no-op.
- Typo fix in the documentation for `JsRealm`.
In our `require()` implementation we use a special logic to resolve
"base path" when looking for matching packages, however this logic
is in contradiction to what needs to happen if there's a local
"node_modules"
directory used. This commit changes require implementation to be aware
if we're running off of global node modules cache or a local one.
