A single database connection ususally maps to a single session.
A connection pool is logically also a session pool. Most
sessions have a way to reset the session state which is desirable
to prevent one bad query from poisoning another later query with
temp table name conflicts or other persistent session resources.
It also lets drivers provide users with better error messages from
queryies when the underlying transport or query method fails.
Internally the driver connection should now be marked as bad, but
return the actual connection. When ResetSession is called on the
connection it should return driver.ErrBadConn to remove it from
the connection pool. Previously drivers had to choose between
meaningful error messages or poisoning the connection pool.
Lastly update TestPoolExhaustOnCancel from relying on a
WAIT query fixing a flaky timeout issue exposed by this
change.

This CL adds back functionality to address the issue that CL 72150
was trying to solve in the first place. That is, it reports the starting
line of the record, so that users have a frame of reference to start with
when debugging what went wrong.
In the event of gnarly CSV files with multiline quoted strings, a parse
failure likely occurs somewhere between the start of the record and
the point where the parser finally detected an error.
Since ParserError.{Line,Column} reports where the *error* occurs, we
add a RecordLine field to report where the record starts.

The Reader implementation is slow because it operates on a rune-by-rune
basis via bufio.Reader.ReadRune. We speed this up by operating on entire
lines that we read from bufio.Reader.ReadSlice.
In order to ensure that we read the full line, we augment ReadSlice
in our Reader.readLine method to automatically expand the slice if
bufio.ErrBufferFull is every hit.
This change happens to fix#19410 because it no longer relies on
rune-by-rune parsing and only searches for the relevant delimiter rune.
In order to keep column accounting simple and consistent, this change
reverts parts of CL 52830.
This CL is an alternative to CL 36270 and builds on some of the ideas
from that change by Diogo Pinela.

On systems that use kqueue, we always register descriptors for both
EVFILT_READ and EVFILT_WRITE. On at least FreeBSD and OpenBSD, when
the write end of a pipe is registered for EVFILT_READ and EVFILT_WRITE
events, and the read end of the pipe is closed, kqueue reports an
EVFILT_READ event with EV_EOF set, but does not report an EVFILT_WRITE
event. Since the write to the pipe is waiting for an EVFILT_WRITE
event, closing the read end of a pipe can cause the write end to hang
rather than attempt another write which will fail with EPIPE.
Fix this by treating EVFILT_READ with EV_EOF set as making both reads
and writes ready to proceed.
The real test for this is in CL 71770, which tests using various
timeouts with pipes.

golang.org/cl/37258 was committed to fix issue #16146.
This patch seemed intent to allow at most one dangling byte. But, as
implemented, many more bytes may actually slip through. This is because
the LZW layer creates a bufio.Reader which will itself consume data
beyond the end of the LZW stream, and this isn't accounted for anywhere.
This change means to avoid the allocation of the bufio.Reader by making
blockReader implement io.ByteReader. Further, it adds a close() method
which detects extra data in the block sequence. To avoid any
regressions with poorly encoded GIFs which may have worked accidentally,
there are no restrictions on how many extra bytes may exist in the final
full sub-block that contained LZW data. If the end of the LZW stream
happened to align with the end of a sub-block, at most one more
sub-block with a length of 1 byte may exist before the block terminator.
This change aims to be at least as performant as the prior
implementation. But the primary gain is avoiding the allocation of a
bufio.Reader per frame:

When building test binaries, we build one archive with all of the test
sources and a second archive with the generated test package main and
link them together. If the test sources are themselves in package main
and the test was compiled with non-default compiler flags, then both
archives will contain a go.cuinfo.producer.main symbol, leading to a
duplicate symbol failure.
This has been causing test build failures on darwin-arm-a1428ios,
darwin-arm64-a1549ios, linux-amd64-noopt, android-arm-wiko-fever, and
android-arm64-wiko-fever since CL 71430 added this symbol. This CL
should fix the build.

No test because at present it is never called in a way that fails.
When #22114 is implemented, failure will be possible. Not including this
change in that work because this change is separable and clearly correct.
Updates #22114

StructField.ByteSize is almost always unset; document that Type.Size()
is the place to look.
The dwarf package doesn't spend much effort teaching you DWARF, so I
don't know what level of handholding is appropriate. Still, no harm in a
little comment.
Closes#21093
