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.

* 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.

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.
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.

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).

Fixes#5850
What was happening:
It seems that his MetaMask had crashed while some new transactions had
been loading defaults. He probably had a network connectivity issue to
Infura (which we are working with Infura to address).
As a result of this network cutout, his three unapproved transactions
were not marked failed, and were not marked as `loadingDefaults =
false`, as their gas prices had not yet been estimated.
Normally this behavior is supposed to clean itself up when the
transaction controller starts up, via the
`TransactionController._onBootCleanUp()` function, but in this case,
during unlock, that function was unable to do its job because when it
requested the transaction list, the current network was in the `loading`
state, making it proceed as if there were no pending transactions.
To fix this, I am doing two things:
- Setting transactions to loadingDefaults = false in more catch blocks.
- Calling `onBootCleanUp()` when the network store's status changes, so
that it will re-trigger when loading completes.
* Fixed reference
* Fixed infinite loop bug
Was refreshing the tx list on every tx state change instead of just
network changes, creating an infinite loop.
* Add notes to tx updates to clarify logs
* Auto fail transactions that have been approved for over 12 hours
Converts txs using a migration.
This migration uses a new helper function that generates tx-failing
migrations, and only requires a version, error message, and condition to
run on each transaction.
* Linted
* Only migrate approved txs to failed
* Cleanup
* Cleanup
* Small lint fixes
* transactions - use safe-event-emitter over events
* tests - pass a platform object on init with a noop showTransactionNotification
* test - fix for tx-state-history-helper trying to reduce an empty array
