* changing the integration tests to show errors. The drive file is reduced to nothing now

* adding more to readme

* rebase to master and removing unused import

* changing readme

* Reland "add limited analysis options (#17332)"

This time I'm starting without Cirrus. Will add Cirrus serpartely from code changes.

This reverts commit 6d33ee1a.

* disable Cirrus analysis check

Fix problem that using multi-engines, sometimes OpenGL would crash be cause of invalid EAGLContext (#17366)

This reverts commit 53891596.

Re-enabling tracked in https://github.com/flutter/flutter/issues/53399.

add limited analysis options

* improving felt: running target unit tests, cleaning up used proccesses

* removing null check

1. Simple "GPU thread" to "raster thread" replacement.

2. Regex replace "GPU([\n\r\s]+//+ thread)" with "raster$1".

3. Regex replace "// gpu$" with "// raster".

4. Simple test change.

5. Run ci/format.sh

* Android change to match the google internal changes.

* Fix format.

* Revert format change, add super call.

* Remove comment for API version.

preserve Window callback zones

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.

Allow drawing raster cache results whose device rect is one pixel larger than the cached image (#17278)

RasterCacheResult::draw constructs the device target rectangle by
calling SkRect::roundOut, which rounds down the left/top coordinates
and rounds up the right/bottom coordinates.  The rounding can produce
a device rect whose width and/or height differs from the cache result
image's width/height by one pixel.

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).
