Rewrites 3 ops that used "op(deferred)" to use "op2(async(lazy))"
instead.
This will allow us to remove codepath for handling "deferred" ops in
"deno_core".
Closes #14122.
Adds two extensions to `--allow-run` behaviour:
- When `--allow-run=foo` is specified and `foo` is found in the `PATH`
at startup, `RunDescriptor::Path(which("foo"))` is added to the
allowlist alongside `RunDescriptor::Name("foo")`. Currently only the
latter is.
- When run permission for `foo` is queried and `foo` is found in the
`PATH` at runtime, either `RunDescriptor::Path(which("foo"))` or
`RunDescriptor::Name("foo")` would qualify in the allowlist. Currently
only the latter does.
Adds `runtime/shared.rs` which is imported by both `build.rs` and the
rest of the crate, containing utilities used by both.
Renames the `snapshot_from_snapshot` feature to
`exclude_runtime_main_js` since that's what it does and it's relevant
outside of snapshotting when `__runtime_js_sources` is specified.

This patch adds a `remote` backend for `ext/kv`. This supports
connection to Deno Deploy and potentially other services compatible with
the KV Connect protocol.
To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:
- [x] Process stdin/stdout/stderr are lazily created
- [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added

Closes #19399 (running without snapshots at all was suggested as an
alternative solution).
Adds a `__runtime_js_sources` pseudo-private feature to load extension
JS sources at runtime for faster development, instead of building and
loading snapshots or embedding sources in the binary. Will only work in
a development environment obviously.
Try running `cargo test --features __runtime_js_sources
integration::node_unit_tests::os_test`. Then break some behaviour in
`ext/node/polyfills/os.ts` e.g. make `function cpus() {}` return an
empty array, and run it again. Fix and then run again. No more build
time in between.
This commit adds new "--deny-*" permission flags. These are complimentary to
"--allow-*" flags.
These flags can be used to restrict access to certain resources, even if they
were granted using "--allow-*" flags or the "--allow-all" ("-A") flag.
Eg. specifying "--allow-read --deny-read" will result in a permission error,
while "--allow-read --deny-read=/etc" will allow read access to all FS but the
"/etc" directory.
Runtime permissions APIs ("Deno.permissions") were adjusted as well, mainly
by adding, a new "PermissionStatus.partial" field. This field denotes that
while permission might be granted to requested resource, it's only partial (ie.
a "--deny-*" flag was specified that excludes some of the requested resources).
Eg. specifying "--allow-read=foo/ --deny-read=foo/bar" and then querying for
permissions like "Deno.permissions.query({ name: "read", path: "foo/" })"
will return "PermissionStatus { state: "granted", onchange: null, partial: true }",
denoting that some of the subpaths don't have read access.
Closes #18804.

This addresses issue #19918.
## Issue description
Event messages have the wrong isTrusted value when they are not
triggered by user interaction, which differs from the browser. In
particular, all MessageEvents created by Deno have isTrusted set to
false, even though it should be true.
This is my first ever contribution to Deno, so I might be missing
something.
Code run within Deno-mode and Node-mode should have access to a
slightly different set of globals. Previously this was done through a
compile time code-transform for Node-mode, but this is not ideal and has
many edge cases, for example Node's globalThis having a different
identity than Deno's globalThis.
This commit makes the `globalThis` of the entire runtime a semi-proxy.
This proxy returns a different set of globals depending on the caller's
mode. This is not a full proxy, because it is shadowed by "real"
properties on globalThis. This is done to avoid the overhead of a full
proxy for all globalThis operations.
The globals between Deno-mode and Node-mode are now properly segregated.
This means that code running in Deno-mode will not have access to Node's
globals, and vice versa. Deleting a managed global in Deno-mode will
NOT delete the corresponding global in Node-mode, and vice versa.
