Brad Fitzpatrick 29264c6f4f json: use strconv.Append variants to avoid allocations in encoding
Before/after, best of 3:
json.BenchmarkCodeEncoder  10  183495300 ns/op  10.58 MB/s
->
json.BenchmarkCodeEncoder  10  133025100 ns/op  14.59 MB/s

But don't get too excited about this.  These benchmarks, while
stable at any point of time, fluctuate wildly with any line of
code added or removed anywhere in the path due to stack splitting
issues.

It's currently much faster, though, and this is the API that
doesn't allocate so should always be faster in theory.

Russ Cox 2666b815a3 use new strconv API
All but 3 cases (in gcimporter.go and hixie.go)
are automatic conversions using gofix.

No attempt is made to use the new Append functions
even though there are definitely opportunities.

Rob Pike f4cd80224a encoding: move asn1, csv, gob, json, xml into encoding
This is Go 1 package renaming CL #1.
This one merely moves the source; the import strings will be
changed after the next weekly release.

The only edits are in Makefiles.
