This should have been removed in 45c12efb4635. Not a correctness
issue, but unnecessary work.
This CL also adds paranoia checks in removeDep so this doesn't
happen again.

This isn't clearly a bug on Go's part, but it triggers a bug in Firefox
which means that crypto/tls and net/http cannot be wired up together
unless NextProtos includes "http/1.1". When net/http sets up the
tls.Config, it does this and so works fine. But anyone setting up the
tls.Config themselves will hit the Firefox bug.
Fixes#5445.

Failures caused by errors like invalid signatures or missing hash
functions cause rather generic, unhelpful error messages because no
trust chain can be constructed: "x509: certificate signed by unknown
authority."
With this change, authority errors may contain the reason why an
arbitary candidate step in the chain was rejected. For example, in the
event of a missing hash function the error looks like:
x509: certificate signed by unknown authority (possibly because of
"crypto/x509: cannot verify signature: algorithm unimplemented" while
trying to verify candidate authority certificate 'Thawte SGC CA')

Share garbage between different bufio Readers. When a Reader
has zero buffered data, put its buffer into a pool.
This acknowledges that most bufio.Readers eventually get
read to completion, and their buffers are then no longer
needed.

The stack scanner for not started goroutines ignored the arguments
area when its size was unknown. With this change, the distance

Allocs of size 16 can bypass atomic set of the allocated bit, while allocs of size 8 can not.
Allocs with and w/o type info hit different paths inside of malloc.

Finer-grained transfers were relevant with per-M caches,
with per-P caches they are not relevant and harmful for performance.
For few small size classes where it makes difference,
it's fine to grab the whole span (4K).

The PKCS#1 spec requires that the PS padding in an RSA message be at
least 8 bytes long. We were not previously checking this. This isn't
important in the most common situation (session key encryption), but
the impact is unclear in other cases.
This change enforces the specified minimum size.
