First, skip all the allocation count tests.
In some cases this aligns with existing skips for -race, but in others
we've got new issues. These are debug modes, so some performance loss is
expected, and this is clearly no worse than today where the tests fail.
Next, skip internal linking and static linking tests for msan and asan.
With asan we get an explicit failure that neither are supported by the C
and/or Go compilers. With msan, we only get the Go compiler telling us
internal linking is unavailable. With static linking, we segfault
instead. Filed #70080 to track that.
Next, skip some malloc tests with asan that don't quite work because of
the redzone.
This is because of some sizeclass assumptions that get broken with the
redzone and the fact that the tiny allocator is effectively disabled
(again, due to the redzone).
Next, skip some runtime/pprof tests with asan, because of extra
allocations.
Next, skip some malloc tests with asan that also fail because of extra
allocations.
Next, fix up memstats accounting for arenas when asan is enabled. There
is a bug where more is added to the stats than subtracted. This also
simplifies the accounting a little.
Next, skip race tests with msan or asan enabled; they're mutually
incompatible.

When I read omitempty option in encoding/xml package, I find it's
a bit different than encoding/json package.
I think it's more precise to say:
"any array, slice, map, or string of length zero."

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

to arrays of structs.

Package documentation of encoding/csv says:

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.

This reverts commit 8a0fbd75a5.
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).
For #65691 (will reopen manually).

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.
Fixes#65691.
