0bfece06d7 net: remove unused nil check
This is part 1 of a series of proposals to fix issue 4369.

In resolving issue 3507 it was decided not to nil out the inner conn.fd field to avoid a race. This implies the checks for fd == nil inside incref/decref are never true.

Removing this logic removes one source of errClosing error values, which affects issue 4373 and moves towards bradfitz's request that fd.accept() return io.EOF when closed concurrently.

Update #4369.

de58eb9091 go/printer: leave indentation alone when printing nodes from different files
ASTs may be created by various tools and built from nodes of
different files. An incorrectly constructed AST will likely
not print at all, but a (structurally) correct AST with bad
position information should still print structurally correct.

One heuristic used was to reset indentation when the filename
in the position information of nodes changed. However, this
can lead to wrong indentation for structurally correct ASTs.

Fix: Don't change the indentation in this case.

Related to issue 4300.

8b7ea6489c exp/locale/collate: changed implementation of Compare and CompareString to

by removing the need for an explicit buffer to be passed as an argument.
This considerably speeds up Compare and CompareString.  This change also eliminates
the need to reinitialize the normalization buffer for each use of an iter. This
also significantly improves performance for Key and KeyString.

Do not skip the first symbol in the symbol table. Any other indexes

will now refer to the symbol following the one that was intended.

Add an object that contains debug relocations, which debug/dwarf
failed to decode correctly. Extend the relocation tests to cover
this case.

Note that the existing tests passed since the symbol following the
symbol that required relocation is also of type STT_SECTION.

063c13a34c runtime/race: more precise handling of finalizers
Currently race detector runtime just disables race detection in the finalizer goroutine.
It has false positives when a finalizer writes to shared memory -- the race with finalizer is reported in a normal goroutine that accesses the same memory.
After this change I am going to synchronize the finalizer goroutine with the rest of the world in racefingo(). This is closer to what happens in reality and so
does not have false positives.
And also add README file with instructions how to build the runtime.

1120982590 reflect: add ArrayOf, ChanOf, MapOf, SliceOf
In order to add these, we need to be able to find references
to such types that already exist in the binary. To do that, introduce
a new linker section holding a list of the types corresponding to
arrays, chans, maps, and slices.

To offset the storage cost of this list, and to simplify the code,
remove the interface{} header from the representation of a
runtime type. It was used in early versions of the code but was
made obsolete by the kind field: a switch on kind is more efficient
than a type switch.

In the godoc binary, removing the interface{} header cuts two
words from each of about 10,000 types. Adding back the list of pointers
to array, chan, map, and slice types reintroduces one word for
each of about 500 types. On a 64-bit machine, then, this CL *removes*
a net 156 kB of read-only data from the binary.

This CL does not include the needed support for precise garbage
collection. I have created issue 4375 to track that.

This CL also does not set the 'algorithm' - specifically the equality
and copy functions - for a new array correctly, so I have unexported
ArrayOf for now. That is also part of issue 4375.

Fixes #2339.
