Add a new, simple interface for scanning (probably textual) data,
based on a new type called Scanner. It does its own internal buffering,
so should be plausibly efficient even without injecting a bufio.Reader.
The format of the input is defined by a "split function", by default
splitting into lines. Other implemented split functions include single
bytes, single runes, and space-separated words.
Here's the loop to scan stdin as a file of lines:
s := bufio.NewScanner(os.Stdin)
for s.Scan() {
fmt.Printf("%s\n", s.Bytes())
}
if s.Err() != nil {
log.Fatal(s.Err())
}
While we're dealing with spaces, define what space means to strings.Fields.
Fixes#4802.

(Offsetof is a function of Alignof and Sizeof.)
- removed IntSize, PtrSize from Context (set Sizeof instead)
- GcImporter needs a Context now (it needs to have
access to Sizeof/Alignof)
- removed exported Size field from Basic (use Sizeof)
- added Offset to Field
- added Alignment, Size to Struct

On Windows, directory names in PATH can be fully or partially quoted
in double quotes ('"'), but the path names as used by most APIs must
be unquoted. In addition, quoted names can contain the semicolon
(';') character, which is otherwise used as ListSeparator.
This CL changes SplitList in path/filepath and LookPath in os/exec
to only treat unquoted semicolons as separators, and to unquote the
separated elements.
(In addition, fix harmless test bug I introduced for LookPath on Unix.)

The data file should be opened when a Conn is first
established, rather than waiting for the first Read or
Write.
Upon Close, we now make sure to try to close both, the
ctl as well as data files and set both to nil, even in
the face of errors, instead of returning early.
The Accept call was not setting the remote address
of the connection properly. Now, we read the correct
file.
Make functions that establish Conn use newTCPConn
or newUDPConn.

This avoids ambiguity and makes the diagnostics closer to
those issued by gc, but it is more verbose since it qualifies
intra-package references.
Without extra context---e.g. a 'from *Package' parameter to
Type.String()---we are forced to err on one side or the other.
Also, cosmetic changes to exp/ssa:
- Remove package-qualification workaround in Function.FullName.
- Always set go/types.Package.Path field to the import path,
since we know the correct path at this point.
- In Function.DumpTo, show variadic '...' and result type info,
and delete now-redundant "# Type: " line.

Also:
- faster code for example extraction
- simplify handling of command documentation:
all "main" packages are treated as commands
- various minor cleanups along the way
For commands written in Go, any doc.go file containing
documentation must now be part of package main (rather
then package documentation), otherwise the documentation
won't show up in godoc (it will still build, though).
For commands written in C, documentation may still be
in doc.go files defining package documentation, but the
recommended way is to explicitly ignore those files with
a +build ignore constraint to define package main.
Fixes#4806.

If Python blocks in the SSL handshake it seems to be
completely uninterruptible, and I've been seeing it
block for at least hours recently. I don't know if the
problem is on the client side or the server side or
somewhere in the network, but setting the timeout
at least means you're guaranteed a new shell prompt
(after printing some errors).

If a test can be placed in the same package ("internal"), it is placed
there. This facilitates testing of package-private details. Because of
dependency cycles some packages cannot be tested by internal tests.

The current implementation would store all cookies received from
any .com domain under "com" in the entries map if a nil public
suffix list is used in constructing the Jar. This is inefficient.
This CL uses the TLD+1 of the domain if the public suffix list
is nil which has two advantages:
- It uses the entries map efficiently.
- It prevents a host foo.com to set cookies for bar.com.
(It may set the cookie, but it won't be returned to bar.com.)
A domain like www.british-library.uk may still set a domain
cookie for .british-library.uk in this case.
The behavior for a non-nil public suffix list is unchanged, cookies
are stored under eTLD+1 in this case.

The routine that adds an automatic to the stack was
adding ptrsize-1 to the size before rounding up.
That addition would only make sense to turn a round down
into a round up. Before a round up, it just wastes a word.
The effect was that a 6c function with one local and
one two-word function call used (8+8)+(16+8) = 40 bytes
instead of 8+16 = 24 bytes.
The wasted space mostly didn't matter, but one place where
it does matter is when trying to stay within the 128-byte
total frame constraint for #pragma textflag 7 functions.
This only affects the C compilers, not the Go compilers.
5c already had correct code, which is now copied to 6c and 8c.

Re-enable TestUpdateAndDelete, TestExpiration, TestChromiumDomain and
TestChromiumDeletion on Windows.
Sorting of cookies with same path length and same creation
time is done by an additional seqNum field.
This makes the order in which cookies are returned in Cookies
deterministic, even if the system clock is manipulated or on
systems with a low-resolution clock.
The tests now use a synthetic time: This makes cookie testing
reliable in case of bogus system clocks and speeds up the
expiration tests.

Fix the sa_mask member of the sigaction struct - on FreeBSD this is
declared as a sigset_t, which is an array of four unsigned ints.
Replace the current int64 with Sigset from defs_freebsd_GOARCH, which
