The videos on the front page are always the same width, regardless of

to its container regardless of layout. It uses the standard hack for
making iframes responsive, but the videos are loaded at random and do
not have uniform aspect ratios so that information is injected into the
DOM using custom properties. If these are not supported, it falls back
to the same layout present before this change.

I've reorganized the guide and rewritten large sections.
The structure is now more clear and logical, and can
be understood and navigated using the summary displayed at
the top of the page (before, the summary was confusing because
the guide contained H1s that were being ignored by the summary).
Both the initial onboarding process and the Gerrit
change submission process have been reworked to
include a concise checklist of steps that can be
read and understood in a few seconds, for people
that don't want or need to bother with details.
More in-depth descriptions have been moved into
separate sections, one per each checklist step.
This is by far the biggest improvement, as the previous
approach of having to read several pages just to understand
the requires steps was very scaring for beginners, in
addition of being harder to navigate.
GitHub pull requests have been integrated as a different
way to submit a change, suggested for first time contributors.
The review process has been described in more details,
documenting the workflow and the used conventions.
Most miscellanea have been moved into an "advanced
topics" chapter.
Paragraphs describing how to use git have been removed
to simplify reading. This guide should focus on Go contribution,
and not help users getting familiar with git, for which many
guides are available.

The EBNF production

was used in FunctionDecl, MethodDecl, and FunctionLit, but only
for the latter it shortened the syntax slightly.
This change "inlines" Function which simplifies FunctionDecl and
MethodDecl and gets rid of the Function production.
This has no impact on the specified language. Also, the Function
production is never referred to by the prose, so it's safe to
remove it from the spec.
Finally, neither go/ast nor go/parser have a representation of
this production via a corresponding node or parse function, so
no possibly valuable documentation is lost, either.

"named type" to "defined type" to avoid confusion with types denoted

them.
Now the spec consistently uses the terms:
- "defined type" for a type declared via a type definition
- "type name" for any name denoting an (alias or defined) type
- "alias" for a type name declared in an alias declaration
New prose is encouraged to avoid the term "named type" to counter-
