The CSS is now served as an external file instead of being injected.
This was done to improve performance. Ideally we would come to a middle
ground between this and the former behaviour by injecting only the CSS
that was required for the initial page load, then lazily loading the
rest. However that change would be more complex. The hope was that
making all CSS external would at least be a slight improvement.
Performance metrics were collected before and after this change to
determine whether this change actually helped. The metrics collected
were the timing events provided by Chrome DevTools:
* DOM Content Loaded (DCL) [1]
* Load (L) [2]
* First Paint (FP) [3]
* First Contentful Paint (FCP) [3]
* First Meaningful Paint (FMP) [3]
Here are the results (units in milliseconds):

Unfortunately, using an external CSS file made no discernible improvement
to the overall page load time. DCM and L were practically identical, and
FCP and FMP were marginally better (well within error margins).
However, the first paint time was _dramatically_ improved. This change
seems worthwhile for the first paint time improvement alone. It also
allows us to delete some code and remove a dependency.
The old `css.js` module included two third-party CSS files as well, so
those have been imported into the main Sass file. This was easier than
bundling them in the gulpfile.
The resulting CSS bundle needs to be served from the root because we're
using a few `@include` rules that make this assumption. We could move
this under `/css/` if desired, but we'd need to update each of these
`@include` rules.

Set the minimum browser version supported in the extension manifest.
Currently we only ship the extension on Chrome and Firefox, so the
minimum version has been set for those two browsers.

* Abstract domain provider from its stream transport
Creating new provider-consuming extensions, like [a new
platform](https://github.com/MetaMask/metamask-extension/blob/develop/docs/porting_to_new_environment.md)
can be frustrating for new contributors because our provider
construction has been tangled with our streaming interface.
Here I've broken up our streaming domain connection from the provider
construction, so developers can more easily construct local and
domain-restricted providers without dealing with streams.
* Abstract public API from stream interface
* clean up noop
* Document non-streaming interface
* getSiteMetadata must be async
* Clean up filters on stream end
* Document cleaning up filters
* Allow named filterMiddleware to be cleaned up
* Linted
* Require site metadata
* Destroy any destroyable middleware during cleanup
* Lint
The Drizzle tests have not been used for some time. They were used to
ensure compatibility with newer versions of `web3` v1. If we want to
re-add tests to ensure compatibility with newer `web3` versions, we
should find some way of doing that more reliably than was done here -
these tests were somewhat flaky and unreliable.
We've been using the `eslint-plugin-json` plugin for some time, but we
haven't been visiting `.json` files in the lint script. The lint script
has now been updated to incude `.json` files, which means any invalid
JSON will result in a lint error.
Unfortunately this JSON plugin doesn't seem to apply the other eslint
rules (such as `key-spacing`) to the JSON files. I wasn't able to find a
way to get that to work. Instead I manually auto-formatted each of the
locale `message.json` files, which fixed many whitespace
inconsistencies.
The `states.json` file was deleted completely, as it appears to be
unused. It wasn't a valid JSON file anyway, it was JavaScript. It looks
like a `states.js` file is automatically generated, but an old copy was
accidentally saved as `states.json` and included in the repo.
Many duplicate key errors were found and fixed in the
`development/states/` JSON files.
`package-lock.json` was added to `.eslintignore` because it was very
slow to lint, and linting it doesn't provide much value.
* Add loading spinner to pending tx status label.
* Add border around account icon in top right
* Change style of settings toggle buttons; wrap with local components
* Eliminate large space after settings labels when no description
* Remove network form from advanced tab of settings
* Keep new account container height to contents when in full screen
While working on #6805, I noticed that many variables were being used
before they were declared. Technically this worked fine in practice
because we were using the `transform-es2015-block-scoping` Babel plugin,
which transforms `let` and `const` to `var`, which is hoisted. However,
after removing that Babel transformation, many things broke.
All instances of variables or classes being used before declared have
been fixed.
The `no-use-before-define` eslint rule has been added to catch these
cases going forward. The rule is disabled for function declarations for
the moment, because those are always hoisted. We could disable that too
if we want to, but it's purely stylistic and would require a lot more
changes.
* Introduce delay for eth_estimateGas calls with in test
* Add test that fails when gas estimates of contract method calls without gas are too high.
* Get transaction gas data from unApprovedTxs instead of confirmTransaction
* Fix selection of gas data in gas-modal-page-container.container
* Lint changes related to Version-6.7.2-gasLimitFix
* Fix e2e tests on Version-6.7.2-gasLimitFix
* Fix unit and integration tests for changes from Version-6.7.2-gasLimitFix
* more e2e fixes
* Add assertions for transaction values on confirm screen
* Fix display of transaction amount on confirm screen.
This silences a warning message that was printed to the console whenever
this module was loaded during tests.
The API changes between these two versions were reviewed carefully for
differences. The only difference made was to `PBKDF2_HMAC_SHA256.bytes`,
which was replaced by `Pbkdf2HmacSha256`.
The length argument no longer has a default value, so it has been set
to match what the default value was in the previous version we used,
which is 32 (the SHA256 hash size).
