Certain browsers (Chrome 53, Safari 9.1.2, Firefox 46) won't correctly
follow a directory listing's links if the file name begins with a run
of characters then a colon, e.g. "foo:bar". Probably mistaking it for
a URI. However, they are happy to follow "./foo:bar", so this change
prepends "./" to all link hrefs in the directory listing of
FileServer.

The code wasn't checking to see if the data was still >= 64 bytes
long after aligning it.
Aligning the data is an optimization and we don't actually need
to do it. In fact for smaller sizes it slows things down due to
the overhead of calling the generic function. Therefore for now
I have simply removed the alignment stage. I have also added a
check into the assembly to deliberately trigger a segmentation
fault if the data is too short.

For persistent error handling, the methods of huffmanBitWriter have to be
consistent about how they check errors. It must either consistently
check error *before* every operation OR immediately *after* every
operation. Since most of the current logic uses the previous approach,
we apply the same style of error checking to writeBits and all calls
to Write such that they only operate if w.err is already nil going
into them.
The error handling approach is brittle and easily broken by future commits to
the code. In the near future, we should switch the logic to use panic at the
lowest levels and a recover at the edge of the public API to ensure
that errors are always persistent.

When tracing is started in the middle of program execution,
we already have a number of runnable goroutines and a number
of blocked/in syscall goroutines. In order to reflect these
goroutines in the trace, we emit EvGoCreate for all existing
goroutines. Then for blocked/in syscall goroutines we additionally
emit EvGoWaiting/EvGoInSyscall events. These events don't reset g.ev
during trace analysis. So next EvGoStart finds g.ev set to the
previous EvGoCreate. As the result time between EvGoCreate and
EvGoStart is accounted as scheduler latency. While in reality
it is blocking/syscall time.
Properly reset g.ev for EvGoWaiting/EvGoInSyscall events.

This makes a bunch of changes to package syntax to tweak line numbers
for AST nodes. For example, short variable declaration statements are
now associated with the location of the ":=" token, and function calls
are associated with the location of the final ")" token. These help
satisfy many unit tests that assume the old parser's behavior.
Because many of these changes are questionable, they're guarded behind
a new "gcCompat" const to make them easy to identify and revisit in
the future.
A handful of remaining tests are too difficult to make behave
identically. These have been updated to execute with -newparser=0 and
comments explaining why they need to be fixed.

Although the term “RSA” is almost synonymous with PKCS#1 v1.5, that
standard is quite flawed, cryptographically speaking. Bellare and
Rogaway fixed PKCS#1 v1.5 with OAEP (for encryption) and PSS (for
signatures) but they only see a fraction of the use of v1.5.
This change adds support for creating and verifying X.509 certificates
that use PSS signatures. Sadly, every possible dimension of flexibility
seems to have been reflected in the integration of X.509 and PSS
resulting in a huge amount of excess complexity. This change only
supports one “sane” configuration for each of SHA-{256, 384, 512}.
Hopefully this is sufficient because it saves a lot of complexity in the
code.
Although X.509 certificates with PSS signatures are rare, I'm inclined
to look favourably on them because they are sufficiently superior.
