Motivation:
* Previously, the size of the compressed data was used for metrics,
rather than the uncompressed size. This causes the library to appear
to perform poorly relative to C or other implementation. Switch it
to use the uncompressed size so that it matches how decompression
benchmarks are usually done (like in compress/flate). This also makes
it easier to compare bzip2 rates to other algorithms since they measure
performance in this way.
* Also, reset the timer after doing initialization work.

The bzip2 block size is a multiple of 100*1000 not 100*1024.
Thus, the bzip2 decoder would incorrectly decode files with larger
block sizes when it should have otherwise failed.
Fortunately, we can correct this in a backwards compatible way since
Go has no implementation of a bzip2 encoder to produce bad blocks :)
To confirm that the C bzip2 utlity chokes on this data:
$ echo "425a683131415926535936dc55330063ffc0006000200020a40830008b00

The LZ77 portion of DEFLATE is relatively self-contained. For the
decompression side of things, we extract this logic out for the
following reasons:
* It is easier to test just the LZ77 portion of the logic.
* It reduces the noise in the inflate.go
Also, we adjust the way that callbacks are handled in the inflate.
Instead of using functions to abstract the logical componets of
huffmanBlock(), use goto statements to jump between the necessary
sections. This is faster since it avoids a function call and is
arguably more readable.

Once upon a time fmt did use bytes.Buffer for its buffer.
The buffer write methods still mimic the bytes.Buffer signatures.
The current code depends on manipulating the buffer []bytes array directly
which makes going back to bytes.Buffer by only changing the type of buffer
impossible. Since type buffer is not exported the methods can be simplified
to the needs of fmt. This saves space and avoids unnecessary overhead.
Use WriteString instead of Write for known inputs since
WriteString is faster than Write to append the same data.
This also saves space in the binary.
Remove the add method from Printer and depending on the data to be written
use WriteRune or WriteByte directly instead.
In total makes the go binary around 4 kilobyte smaller.

The current implementations of the AppendQuote functions use quoteWith
(through Quote) for quoting the given value and appends the returned
string to the dst byte slice. quoteWith internally creates a byte slice
on each call which gets converted to a string in Quote.
This means the AppendQuote functions always allocates a new byte slice
and a string only to append them to an existing byte slice. In the case
of (Append)QuoteRune the string passed to quoteWith will also needs to
be allocated from a rune first.
Split quoteWith into two functions (quoteWith and appendQuotedWith) and
replace the call to Quote inside AppendQuote with appendQuotedWith,
which appends directly to the byte slice passed to AppendQuote and also
avoids the []byte->string conversion.
Also introduce the 2 functions quoteRuneWith and appendQuotedRuneWith
that work the same way as quoteWith and appendQuotedWith, but take a
single rune instead of a string, to avoid allocating a new string when
appending a single rune, and use them in (Append)QuoteRune.
Also update the ToASCII and ToGraphic variants to use the new functions.

Instead require the used Reader to implement the public RuneScanner
interface.
The extra implementation logic for UnreadRune is removed from ScanState.
Instead the readRune wrapper is extended to implement UnreadRune for the
RuneScanner interface. If the Reader passed to newScanstate does not

missing functionality.
Note that a RuneReader that does not implement RuneScanner will also
be wrapped by runeRead which was not the case before.
Performance with the readRune wrapper is better than without before.

A slice uses less memory than a NodeList, and has better memory locality
when walking the list.
This uncovered a tricky case involving closures: the escape analysis
pass when run on a closure was appending to the Dcl list of the OCLOSURE
rather than the ODCLFUNC. This happened to work because they shared the
same NodeList. Fixed with a change to addrescapes, and a check to
Tempname to catch any recurrences.
This removes the last use of the listsort function outside of tests.
I'll send a separate CL to remove it.
Unfortunately, while this passes all tests, it does not pass toolstash
-cmp. The problem is that cmpstackvarlt does not fully determine the
sort order, and the change from listsort to sort.Sort, while generally
desirable, produces a different ordering. I could stage this by first
making cmpstackvarlt fully determined, but no matter what toolstash -cmp
is going to break at some point.

Check the function types before compiling the tests. Extend the same
approach taken by the type check used for TestMain function.
To keep existing behavior, wrong arguments for TestMain are ignored
instead of causing an error.
Fixes#14226.

In normal mode the test runs for 9+ seconds on my machine (48 cores).
But the real problem is race mode, in race mode it hits 10m test timeout.
Reduce test size in short mode. Now it runs for 100ms without race.

Previously, RawQuery was used to indicate the presence of a query
string in url.URL. However, this approach was not able to differentiate
between URLs that have no query string at all (http://foo.bar/) and
those that have a query with no values (http://foo.bar/?).
Add a ForceQuery field to indicate the latter form of URL and use it
in URL.String to create a matching URL with a trailing '?'.

Currently dropg does not unwire locked g/m.
This is unnecessary distiction between locked and non-locked g/m.
We always restart goroutines with execute which re-wires g/m.
First, this produces false sense that this distinction is necessary.
Second, it can confuse some sanity and cross checks. For example,
if we check that g/m are unwired before we wire them in execute,
the check will fail for locked g/m. I've hit this while doing some
race detector changes, When we deschedule a goroutine and run
scheduler code, m.curg is generally nil, but not for locked ms.
Remove the distinction.

The existing documentation for ParsePKIXPublicKey is difficult to understand
and the return type of the parsed public key are not mentioned explicitly.
Descriptions about types of public key supported, as well as an example on
how to use type assertions to determine return type of a parsed public key
has been added.
