2112fed743 crypto/tls: support TLS 1.1.
The significant change between TLS 1.0 and 1.1 is the addition of an explicit IV in the case of CBC encrypted records. Support for TLS 1.1 is needed in order to support TLS 1.2.

781b2a2519 cmd/cc: support 21-bit runes in wide string constants
Changeset 7557a627e9b5 added a temporary stop-gap to silence
a print format warning for %S. This has been reverted.

None of this code is original. It was copied from the latest
Plan 9 compilers.

636169405c build: add intptr typedef for Plan 9
Revision 01810e5c68e9 added the following to src/pkg/runtime/stack.h:

        StackPreempt = (uintptr)(intptr)0xffffade,

The typedef for intptr is defined in two places:

        1. src/pkg/runtime/runtime.h for use by the runtime

        2. include/u.h for use by the compilers and linkers

On Plan 9, we don't use include/u.h but instead augment the host's
u.h with extra typedefs. These are in include/plan9/GOARCH/u.h.

We forgot to add intptr. It didn't cause a problem until now since
that typedef was never used outside the runtime.

2bcc30891c codereview: don't warn about secret commits
Normally the codereview plugin disables adding new commits
when not using the submit command. Unfortunately this makes
it impossible to use the Mercurial Queues extension at the
same time.

A feature called "Phases" was introduced in Mercurial 2.1
that allows marking commits as being secret; this means
they will never be pushed to the upstream repository.

We can take advantage of this feature to allow the use of
Mercurial Queues if the mq.secret option has been set in
hgrc(5) and a recent version of Mercurial is used.

251baea1af cmd/ld: fix gcdata and gcbss symbols
These two symbols don't show up in the Go symbol table
since they're defined in dodata which is called sometime
after symtab. They do, however, show up in the ELF symbol
table.

This regression was introduced in changeset 01c40d533367.

Also, remove the corresponding strings from the ELF strtab
section now that they're unused.

07b6add0ca runtime: do hashmap grow work during reads.
Before this change, grow work was done only
during map writes to ensure multithreaded safety.
This can lead to maps remaining in a partially
grown state for a long time, potentially forever.
This change allows grow work to happen during reads,
which will lead to grow work finishing sooner, making
the resulting map smaller and faster.

Grow work is not done in parallel.  Reads can
happen in parallel while grow work is happening.
