We currently use a mix of C standard includes (e.g. limits.h) and their
C++ variants (e.g. climits). This migrates to a consistent style for all
cases where the C++ variants are acceptable, but leaves the C
equivalents in place where they are required, such as in the embedder
API and other headers that may be used from C.
This functionality is added in issue #41523. Allows runners to request
the singleton instance of `sys::ComponentContext`, while it remains also
accessible to component-specific code that does not have direct access
to top-level objects.
Fixes#41523
close() returns a nonzero in case of an error. Old code had it log
only when *no* error happens on close, which is exactly the opposite
of what we want.
On Fuchsia, we can now get executable VMOs from trusted backing
filesystems. This allows us to remove the use of replace_as_executable
in favor of opening files with `fdio_open_fd_at` with the
`OPEN_RIGHT_EXECUTABLE` flag and getting VMOs by calling
`fdio_get_vmo_exec`.
By moving the responsibility for executability into the filesystem, we
are able to remove `deprecated-ambient-replace-as-executable` from
component manifests for non-JIT runners (the JIT runners still call
replace_as_executable in Dart's allocator). It wasn't abundantly clear
whether .cmx files for tests were used purely in AOT runtime
environments or also saw JIT usage, so I left those as-is.
For context: this is a second attempt at #16690, which was reverted
because it broke the Dart JIT runner. The primary difference is that
this time around, we correctly handle absolute vs relative paths,
depending on whether library loading bottoms out in `fdio_open_fd` or
`fdio_open_fd_at`. I've added additional assertions to help ensure any
new usages use the correct shape of path.
Testing: I verified locally that the flutter product runner works on
Astro, and also successfully ran the Dart JIT example test (which was
the thing blocking the google3 roll with the previous attempt at this
patchset).

Test: verified locally that this works on Astro on a _user build with
the runtime allowlist tightened.
The timezone data in Fuchsia is at a fixed path. This will have the
flutter runner attempt to load it and log, but not fail if loading
does not work out.
Added two tests
(1) Shows that the specific TZ data version loaded takes effect after
initialization
(2) Shows that when TZ data files are absent the initialization
continues.
Ensure that the string data backing package.resolved_url is not modified
or moved by making a copy to pass as the argument value for
TRACE_DURATION.

Ported from Topaz tree.
Corects a bnuch of typeos throughout teh engien codebsae. Also makes
a couple minor Commonwealth -> US spelling adjustments for consistency
with the rest of Flutter's codebase.
