* Set default advanced tab gas limit
The advanced tab of the transaction confirmation screen would enter
into an infinite loop and crash if the given gas price was falsy and
some interaction was made with the gas limit field.
To prevent this infinite loop, a default value of 0 has been set. The
user will still need to update the gas limit in order to confirm the
transaction, as zero is too low a gas limit (the lowest is 21000).
21000 cannot be the default gas limit at this layer, because the limit
used is from a layer above this, which wouldn't have that same 21000
set.
* Set default gas limit to minimum allowed
A transaction initiated from a dapp might not set a gas limit, which
would result in a default of zero being used in the advanced tab. The
default gas limit in that case has been changed to 21,000, the minimum
allowed gas limit, so that users aren't forced to manually update it.
* Use `AdvancedGasInputs` in `AdvancedTabContent`
The `AdvancedGasInputs` component was originally extracted from the
`AdvancedTabContent` component, duplicating much of the rendering
logic. They have since evolved separately, with bugs being fixed in one
place but not the other.
The inputs and outputs expected weren't exactly the same, as the
`AdvancedGasInputs` component converts the input custom gas price and
limit, and it converts them both in the setter methods as well.
The `GasModalPageContainer` had to be adjusted to avoid converting
these values multiple times.
Both components dealt with input debouncing separately, both in less
than ideal ways. `AdvancedTabContent` didn't debounce either field, but
it did debounce the check for whether the gas limit field was below the
minimum value. So if a less-than-minimum value was set, it would be
propogated upwards and could be saved if the user clicked 'Save'
quickly enough. After a second delay it would snap back to the minimum
value. The `AdvancedGasInputs` component debounced both fields, but
it would replace any gas limit below the minimum with the minimum
value. This led to a problem where a brief pause during typing would
reset the field to 21000.
The `AdvancedGasInputs` approach was chosen, except that it was
updated to no longer change the gas limit if it was below the minimum.
Instead it displays an error. Parent components were checked to ensure
they would detect the error case of the gas limit being set too low,
and prevent the form submission in those cases. Of the three parents,
one had already dealt with it correctly, one needed to convert the
gas limit from hex first, and another needed the gas limit check added.
Closes#6872
* Cleanup send components
Empty README files have been removed, and a mistake in the index file
for the send page has been corrected. The Gas Slider component class
name was updated as well; it looks like it was originally created from
`AdvancedTabContent`, so it still had that class name.
* eslint: Check for unused function arguments
* eslint: Ignore unused '_' in argument list
Also allow any number of '_' e.g., '__' or '___' which is to be used sparingly
* Remove and rename unused arguments
* Extract advanced gas input controls to their own component
* Add advanced inline gas toggle to settings
* Add optional advanced inline gas to send send screen
* Adds optional advanced gas inputs to the confirm screen
* Add info modals for advanced gas inputs.
* Fix translation of advance gas toggle description.
* Lint and unit test fixes for inline-advanced-gas-inputs
* Increase margin above advanced options button on send screen
* Move methods from constructor to property syntax in advanced-gas-inputs.component
