Russ Cox ad37081b67 encoding/json: add test for Unmarshal of malformed data
Roll back CL making primitive type unmarshal faster,
because it broke the Unmarshal of malformed data.

Add benchmarks for unmarshal of primitive types.

Alan Donovan aa0b573ad6 exp/ssa: make Parameters values, not addresses.
We explicitly spill all parameters to the frame during initial
SSA construction.  (Later passes will remove spills.)
We now properly handle local Allocs escaping via Captures.

Ian Lance Taylor e65c0a82ce runtime: use new CNT_MASK in lfstack
This is for SPARC64, a 64-bit processor that uses all 64-bits
of virtual addresses.  The idea is to use the low order 3 bits
to at least get a small ABA counter.  That should work since
pointers are aligned.  The idea is for SPARC64 to set CNT_MASK
== 7, PTR_BITS == 0, PTR_MASK == 0xffffffffffffff8.

Also add uintptr casts to avoid GCC warnings.  The gccgo
runtime code is compiled with GCC, and GCC warns when casting
between a pointer and a type of a different size.

John Graham-Cumming 3c77b8961c net/http: fix Content-Length/Transfer-Encoding on HEAD requests
net/http currently assumes that the response to a HEAD request
    will always have a Content-Length header. This is incorrect.

RFC2616 says: "The HEAD method is identical to GET except that
the server MUST NOT return a message-body in the response. The
metainformation contained in the HTTP headers in response to a
HEAD request SHOULD be identical to the information sent in
response to a GET request. This method can be used for
obtaining metainformation about the entity implied by the
request without transferring the entity-body itself. This
method is often used for testing hypertext links for validity,
accessibility, and recent modification."

This means that three cases are possible: a Content-Length
header, a Transfer-Encoding header or neither. In the wild the
following sites exhibit these behaviours (curl -I):

HEAD on http://www.google.co.uk/ has Transfer-Encoding: chunked
HEAD on http://www.bbc.co.uk/    has Content-Length: 45247
HEAD on http://edition.cnn.com/  has neither header

This patch does not remove the ErrMissingContentLength error
for compatibility reasons, but it is no longer used.

This prevents the occasional issue when Mercurial screws up the locking

binary).

It also asks all builders to poll for new commits.

Alan Donovan 0cbf289b36 go/types: expose types.IsIdentical, the Type equivalence relation.
This function is absolutely critical for clients such as
exp/ssa, and too complex for clients to duplicate.

As with CL 7200046, gri expressed in the doc below [gophers
only] before going on leave that he intended to expose such a
predicate, though his wording suggests as an interface method
of Type rather than a standalone function.  (My preference is
for binary methods to be standalone; see "On Binary Methods",
Kim Bruce, 1995).  In any case if he wishes to move it that's
easily accommodated by clients.

Mikkel Krautz 249af5c85e crypto/x509: skip SystemRootsError test on Windows
On Windows, crypto/x509 passes through to Windows's CryptoAPI
to verify certificate chains. This method can't produce a
SystemRootsError, so make sure we always skip the test on
Windows.

This is needed because testVerify is called in both
TestGoVerify and TestSystemVerify on Windows - one is for
testing the Go verifier, the other one is for testing the
CryptoAPI verifier. The orignal CL tried to sidestep
this issue by setting systemSkip to true, but that only
affected TestSystemVerify.

Marcel van Lohuizen f86ae990e8 exp/locale/collate: preparation for adding Search API. Also changed the collate API
further to how (I believe) it will end up being.
It is nicer to separate search from sorting functionality. Collation needs tables that
are not needed by search and vice-versa.  The common functionality is separated out
in the Weigher interface.  As this interface is very low-level, it will be moved to
a sub package (colltab) in a next CL.
The types that will move to this package are Weigher, Elem, and Level.  The addition
of Elem allows for removing some of the duplicate code between collate and collate/build.
This CL also introduces some stubs for a higher-level API for options. The default
proposed options are quite complex and require the user to have a decent understanding
of Unicode collation.  The new options hide a lot of the complexity.

Further, the passing of Waitmsg data in startProcess
