Rémy Oudompheng fc7b75f216 cmd/gc: fix export data for aggressive inlining.
Export data was broken after revision 6b602ab487d6
when -l is specified at least 3 times: it makes the compiler
write out func (*T).Method() declarations in export data, which
is not supported.

Also fix the formatting of recover() in export data. It was
not treated like panic() and was rendered as "<node RECOVER>".

Akshat Kumar fb451490ec os: don't hold ForkLock across opens on Plan 9
If os.OpenFile holds ForkLock on files that block opens,
then threads that simultaneously try to do fork-exec will
get hung up (until the open succeeds). Blocked opens are
common enough on Plan 9 that protecting against fd leaks
into fork-execs means not being able to do fork-execs
properly in the general case. Thus, we forgo taking the
lock.

Michael Teichgräber ad341843a7 net: SplitHostPort: adjust error message for missing port in IPv6 addresses
An hostport of "[::1]" now results in the same error message
"missing port in address" as the hostport value "127.0.0.1",
so SplitHostPort won't complain about "too many colons
in address" anymore for an IPv6 address missing a port.

Added tests checking the error values.

Fixes #4526.

Andrey Mirtchovski e579395905 encoding/json: properly unmarshal empty arrays.
The JSON unmarshaller failed to allocate an array when there
are no values for the input causing the `[]` unmarshalled
to []interface{} to generate []interface{}(nil) rather than
[]interface{}{}. This wasn't caught in the tests because Decode()
works correctly and because jsonBig never generated zero-sized
arrays. The modification to scanner_test.go quickly triggers
the error:

without the change to decoder.go, but with the change to scanner_test.go:

$ go test
--- FAIL: TestUnmarshalMarshal (0.10 seconds)
decode_test.go:446:		Marshal jsonBig
scanner_test.go:206:	diverge at 70: «03c1OL6$":null},{"[=» vs «03c1OL6$":[]},{"[=^\»
FAIL

Also added a simple regression to decode_test.go.

Jan Ziak 4da6b36fbf runtime: local allocation in mprof.goc
Binary data in mprof.goc may prevent the garbage collector from freeing
memory blocks. This patch replaces all calls to runtime·mallocgc() with
calls to an allocator private to mprof.goc, thus making the private
memory invisible to the garbage collector. The addrhash variable is
moved outside of the .bss section.

James Gray dab268fac3 cmd/cgo: allow for stdcall decorated dynimport names

1. Change the symbol versioning delimiter '@' in cgo's dynimport output to a '#', and in cmd/ld when it parses dynimports.
2. Remove the "@N" decorator from the first argument of cgo's dynimport output (PE only).
