This change makes sure that we are properly checking the ignored field
recursion depth in decIgnoreOpFor consistently. This prevents stack
exhaustion when attempting to decode a message that contains an
extremely deeply nested struct which is ignored.
Thanks to Md Sakib Anwar of The Ohio State University (anwar.40@osu.edu)
for reporting this issue.

Size() is currently not called from the fast path, since the package
handles the buffer sizing for Read and Write internally. This will change
when adding Append() because callers can use Size to avoid allocations when
writing into bytes.Buffer via AvailableBuffer for example.
Add a fast path for simple types and extend the existing struct size cache
to arrays of structs.

Package documentation of encoding/csv says:
> this package supports the format described in RFC 4180.
According to section 2 of RFC 4180:
> Each record is located on a separate line, delimited by a line break (CRLF).
On the other hand, Writer uses LF (not CRLF) as newline character by default.
> If [Writer.UseCRLF] is true, the Writer ends each output line with \r\n instead of \n.
Strictly speaking, this behavior is different from RFC 4180.
Package documentation would improve if we clarify that point.

Beyond the required file move and refactor to use the testing package,
a number of changes were made to get the fuzzing working properly.
First, add more logs to see what is going on.
Second, some option combinations set Comma to the null character,
which simply never worked at all. I suspect the author meant to leave
the comma character as the default instead.
This was spotted thanks to the added logging.
Third, the round-trip DeepEqual check did not work at all
when any comments were involved, as the writer does not support them.
Fourth and last, massage the first and second parsed records before
comparing them with DeepEqual, as the nature of Reader and Writer
causes empty quoted records and CRLF sequences to change.
With all the changes above, the fuzzing function appears to work
normally on my laptop now. I fuzzed for a solid five minutes and
could no longer encounter any errors or panics.

Reason for revert: Breaking real-world tests inside Google,
which means it probably breaks real-world tests outside Google.
One instance I have seen is a <!-- --> comment (often a copyright notice) before the procinst.
Another test checks that a canonicalizer can handle a test input that simply has procinsts mid-XML.
XML is full of contradictions, XML implementations more so. If we are going to start being picky, that probably needs to be controlled by a GODEBUG (and a proposal).

The XML specification requires an XML declaration, if present, to only
appear at the very beginning of the document, not even preceded by
whitespace. The parser currently accepts it at any part of the input.
Rejecting whitespace at the beginning of the file might break too many
users. This change instead only rejects an XML declaration preceded by
a non-whitespace token *and* allows the Encoder to emit whitespace
before an XML declaration. This means that a token stream produced by
the Decoder can be passed to the Encoder without error, while we still
don't emit clearly invalid XML.
This might break programs depending on Decoder allowing arbitrary XML
before the XML declaration.

IsZero does the same thing, using this rather than writing it again.

CL 469555 changed Compact to use append instead of bytes.Buffer.
appendCompact iterates over input src slice and performs escaping
of certain characters.
To optimize copying it does not copy characters one by one
but keeps track of the start offset of the data to copy when
it reaches next character to escape or the end of the input.
This start offset may become greater than input character offset
so copying of preceding data should check this condition.
CL 469555 removed boundary checks for copying data preceding
escaped characters and this change restores them.

Across all encoding packages, linkify declarations if possible.
In some cases, we convert a code block into a bulleted list,
which then further allows for more linkification.

Since #47066 was accepted and implemented,
reflect.Value.Bytes can be called directly on addressable arrays,
so there is no longer a need to go through a slice first.
