The `exampleMap` needs to hold an hash object for each
of the `collectExamples.exampleFolders` paths.

Previously these hash objects were only created if there
was actually an example file the hash's respective
example folder.  This could cause crashes during
`yarn docs-watch` (and so also `yarn sync-and-serve`)
if no examples were read in for a particular run of
the doc-gen.

…mAlias` (#22494)

The disambiguation needs to be done earlier so that the auto-link-code
post-processor can benefit from it.

PR Close #22494

The new version of `dgeni-packages/typescript` no longer strips
out "namespaces" from types, which was part of the problem of
not autolinking correctly to `HttpEventType.Response`.

Another part of the problem was that we did not include `.`
characters when matching potential code blocks for auto-linking,
which precluded properties of enums from being linked.

Finally, members we not being given a `path` property, which is
needed to effectively autolink to them. This is now set in
the `simplifyMemberAnchors` processor.

When I enabled bazel remote caching, I also switched to running
buildifier and skylint from the package.json script, which builds them
from head. With remote caching, we do get cache hits for these, but
looking up the action inputs actually takes quite a bit of time since we
have to first fetch the remote repository, then do loading and
analysis, then read the inputs to determine the cache key.

It's more important to keep the lint job fast, so I'm reverting that
part of the change for now. We can experiment with building them from
head in a less critical repo.

…oded where needed (#22337)

This change brings Angular largely in line with how AngularJS previously serialized URLs. This is based on RFC 3986 and resolves issues such as the above #10280 where URLs could be parsed, re-serialized, then parsed again producing a different result on the second parsing.

Adjustments to be aware of in this commit:

* URI fragments will now serialize the same as query strings
* In the URI path or segments (portion prior to query string and/or fragment), the plus sign (`+`) and ampersand (`&`) will appear decoded
* In the URL path or segments, parentheses values (`(` and `)`) will now appear percent encoded as `%28` and `%29` respectively
* In the URL path or segments, semicolons will be encoded in their percent encoding `%3B`

NOTE: Parentheses and semicolons denoting auxillary routes or matrix params will still appear in their decoded form -- only parentheses and semicolons used as values in a segment or key/value pair for matrix params will be encoded.

While these changes are not considered breaking because applications should be decoding URLs and key/value pairs, it is possible that some unit tests will break if comparing hard-coded URLs in tests since that hard coded string will represent the old encoding. Therefore we are releasing this fix in the upcoming Angular v6 rather than adding it to a patch for v5.
