This reverts the changes to Error from CL 571995, and adds a
GODEBUG controlling the changes to ServeContent/ServeFile/ServeFS.
The change to remove the Content-Encoding header when serving an error
breaks middleware which sets Content-Encoding: gzip and wraps a
ResponseWriter in one which compresses the response body.
This middleware already breaks when ServeContent handles a Range request.
Correct uses of ServeContent which serve pre-compressed content with
a Content-Encoding: gzip header break if we don't remove that header
when serving errors. Therefore, we keep the change to ServeContent/
ServeFile/ServeFS, but we add the ability to disable the new behavior
by setting GODEBUG=httpservecontentkeepheaders=1.
We revert the change to Error, because users who don't want to include
a Content-Encoding header in errors can simply remove the header
themselves, or not add it in the first place.

When a request contains an "Expect: 100-continue" header,
the first read from the request body causes the server to
write a 100-continue status.
This write caused a panic when performed after the server handler
has exited. Disable the write when cleaning up after a handler
exits.
This also fixes a bug where an implicit 100-continue could be
sent after a call to WriteHeader has sent a non-1xx header.
This change drops tracking of whether we've written a
100-continue or not in response.wroteContinue. This tracking
was used to determine whether we should consume the remaining
request body in chunkWriter.writeHeader, but the discard-the-body
path was only taken when the body was already consumed.
(If the body is not consumed, we set closeAfterReply, and we
don't consume the remaining body when closeAfterReply is set.
If the body is consumed, then we may attempt to discard the
remaining body, but there is obviously no body remaining.)

Add an index so that pattern registration isn't always quadratic.
If there were no index, then every pattern that was registered would
have to be compared to every existing pattern for conflicts. This
would make registration quadratic in the number of patterns, in every
case.
The index in this CL should help most of the time. If a pattern has a
literal segment, it will weed out all other patterns that have a
different literal in that position.
The worst case will still be quadratic, but it is unlikely that a set
of such patterns would arise naturally.
One novel (to me) aspect of the CL is the use of fuzz testing on data
that is neither a string nor a byte slice. The test uses fuzzing to
generate a byte slice, then decodes the byte slice into a valid
pattern (most of the time). This test actually caught a bug: see

As far as I can tell, some flakiness is unavoidable in tests
that race a large client request write against a server's response
when the server doesn't read the full request.
It does not appear to be possible to simultaneously ensure that
well-behaved clients see EOF instead of ECONNRESET and also prevent
misbehaving clients from consuming arbitrary server resources.
(See RFC 7230 §6.6 for more detail.)
Since there doesn't appear to be a way to cleanly eliminate
this source of flakiness, we can instead work around it:
we can allow the test to adjust the hard-coded delay if it
sees a plausibly-related failure, so that the test can retry
with a longer delay.
As a nice side benefit, this also allows the tests to run more quickly
in the typical case: since the test will retry in case of spurious
failures, we can start with an aggressively short delay, and only back
off to a longer one if it is really needed on the specific machine
running the test.
Fixes#57084.
Fixes#51104.
For #58398.

Modify ServeMux to handle patterns with methods and wildcards.
Remove the map and list of patterns. Instead patterns
are registered and matched using a routing tree.
We also reorganize the code around "trailing-slash redirection,"
the feature whereby a trailing slash is added to a path
if it doesn't match an existing one. The existing code
checked the map of paths twice, but searching the tree
twice would be needlessly expensive. The rewrite
searches the tree once, and then again only if a
trailing-slash redirection is possible.
There are a few omitted features in this CL, indicated
with TODOs.

Over the past few months as I read the standard library's documentation
I kept finding spots where godoc links would have helped me.
I kept adding to a stash of changes to fix them up bit by bit.
The stash has grown big enough by now, and we're nearing a release,
so I think it's time to merge to avoid git conflicts or bit rot.
Note that a few sentences are slightly reworded,
since "implements the Fooer interface" can just be "implements [Fooer]"
now that the link provides all the context needed to the user.

Do the same as the code above: "case err == errTooLarge", declare
publicErr as a constant to avoid runtime calls.

RemoteAddr can return nil in some cases, this fix prevents a panic.
I chatted with @neild about this beforehand, but what's happening in our
case is that a connection comes in to the HTTP server which is then
immediately closed (we discovered this issue by accident using nmap).
The network implementation that we're using (it happens to be gVisor
via its gonet adaptor) is returning nil from RemoteAddr(), presumably
as there is no remote at that point.
But, ultimately, since RemoteAddr returns an interface it is always
possible for it to return nil, and indeed conn.RemoteAddr in this file
does exactly that if the conn is not ok.
