901e7bfe53 lib9, libmach, cmd/dist, go/build: add support for GOOS=solaris
This change adds solaris to the list of supported operating
systems and allows cmd/dist to be built on Solaris.

This CL has to come first because we want the tools to ignore
solaris-specific files until the whole port is integrated.

8f9844348f syscall: include mmap constants in netbsd zerror* files
Include the <sys/mman.h> header for NetBSD mkerrors.sh. This brings
in constants used with mmap(2), msync(2) and mlockall(2).

The regeneration of the NetBSD zerror* files also picks clone(2)
related constants.

Update #4929.

d227d680ec cmd/gc: use 100x less memory for []byte("string")
[]byte("string") was simplifying to
[]byte{0: 0x73, 1: 0x74, 2: 0x72, 3: 0x69, 4: 0x6e, 5: 0x67},
but that latter form takes up much more memory in the compiler.
Preserve the string form and recognize it to turn global variables
initialized this way into linker-initialized data.

Reduces the compiler memory footprint for a large []byte initialized
this way from approximately 10 kB/B to under 100 B/B.

See also issue 6643.

78c16c9b16 crypto/rsa: support unpadded signatures.
Usually when a message is signed it's first hashed because RSA has low
limits on the size of messages that it can sign. However, some
protocols sign short messages directly. This isn't a great idea because
the messages that can be signed suddenly depend on the size of the RSA
key, but several people on golang-nuts have requested support for
this and it's very easy to do.

02a15e7165 archive/zip: fix bug reading zip64 files
ZIP64 Extra records are variably sized, but we weren't capping
our reading of the extra fields at its previously-declared
size.

No test because I don't know how to easily create such files
and don't feel like manually construction one.  But all
existing tests pass, and this is "obviously correct" (queue
laughter).

Fixes #7069

991e9a8331 net/http: Add more call order tests for request form parsing.
Adds tests for branches handling call ordering which
were shown to be untested by the cover tool.

This is part of the refactoring of form parsing discussed
in CL 44040043. These tests may need to be changed later but
should help lock in the current behaviour.

939b3fa39e net/http: remove todos from cookie code
The Domain and Path field of a parsed cookie have been
the unprocessed wire data since Go 1.0; this seems to
be okay for most applications so let's keep it.

Returning the unprocessed wire data makes it easy to
handle nonstandard or even broken clients without
consulting Raw or Unparsed of a cookie.

The RFC 6265 parsing rules for domain and path are
currently buried in net/http/cookiejar but could be
exposed in net/http if necessary.

d180579170 syscall: handle varied path lengths for unix sockets
Most BSDs include the trailing NUL character of the socket path in the
length, however some do not (such as NetBSD 6.99). Handle this by only
subtracting the family and length bytes from the returned length, then
scanning the path and removing any terminating NUL bytes.

d4c66a35ba runtime: add a test for randomised map iteration order.

0ea20bc981 cmd/6g: inline copies of up to 4 words in length.
This change fixes a serious performance regression
with reflect.Value growing to 4 words instead of 3.
The json benchmark was ~50% slower, with this change
it is ~5% slower (and the binary is 0.5% larger).

Longer term, we probably need to rethink our copy
generation.  Using REP is really expensive time-wise.
