Does as much as possible in data layout instead
of during the init function.

Handles var x = y; var y = z as a special case too,
because it is so prevalent in package unicode
(var Greek = _Greek; var _Greek = []...).

Introduces InitPlan description of initialized data
so that it can be traversed multiple times (for example,
in the copy handler).

Cuts package unicode's init function size by 8x.
All that remains there is map initialization, which
is on the chopping block too.

Fixes sinit.go test case.

Aggregate DATA instructions at end of object file.

Checkpoint.  More to come.

- canonicalize package descriptors
- remove duplicate storage of file paths
- reduces (current) written index file by approx 3.5MB
(from 28434237B to 24686643B, or 13%)

- next step: untangle DAG (when serializing, using
gob, the index dag explodes into an index tree)

1. adds a urlPart field to context
2. implements tURL to figure out the URL part
3. modifies joinContext to allow common context mismatches
   around branches to be ignored when not material as in
   <a href="/foo{{if .HasQuery}}?q={{.Query}}{{/if}}">
4. adds a pipeline function that filters dynamically inserted
   protocols to prevent code injection via URLs.

This CL implements a new godoc feature to save the search
index on disk. Use -write_index to create the search
index file named with -index_files. Use -index_files to
provide a glob pattern specifying index file(s) when
starting godoc; in this case the run-time indexer is not
run.

Known issues:
- saving/restoring full text index is not yet supported
- the list of flags and overall usage logic could use a
  cleanup

Since JavaScript doesn't have [u]int64 types, some JSON APIs
encode such types as strings to avoid losing precision.

This adds a new struct tag option ",string" to cause
fields to be wrapped in JSON strings on encoding
and unwrapped from strings when decoding.

Add openbsd 386 syscall support, partially based on the existing
freebsd 386 syscall implementation.

FTR zerrors_openbsd_386.go cannot currently be completely built on
openbsd/i386 due to what appears to be a gcc bug. The constants can be
successfully generated with -m32 on openbsd/amd64 and the error
table can then be generated on openbsd/i386.
