Fixes issue #1879.
Directives were not directly expanded, but since their
content ended up in makefiles, further expansion would
take place there. This prevents such artifacts by
restricting the set of characters that may be used in
a directive value.
To build the list of safe characters I went through the
contents of /usr/lib/pkgconfig and extracted LDFLAGS
and CFLAGS information, so hopefully this is a
reasonable default to get started.

Makes all.bash work after echo 4 >/proc/cpu/alignment,
which means kill the process on an unaligned access.
The default behavior on DreamPlug/GuruPlug/SheevaPlug
is to simulate an ARMv3 and just let the unaligned accesses
stop at the word boundary, resulting in all kinds of surprises.

-- removes Response.RequestMethod string
-- adds Response.Request *Request
-- removes the finalURL result parameter from client.Get()
-- adds a gofix rule for callers of http.Get which assign
the final url to the blank identifier; warning otherwise
Caller who did:
res, finalURL, err := http.Get(...)

res, err := http.Get(...)
if err != nil {

Previously, whether declaring a type which copied the structure of a type it was referenced in via a pointer field would work depended on whether you declared it before or after the type it copied, e.g. type T2 T1; type T1 struct { F *T2 } would work, however type T1 struct { F *T2 }; type T2 T1 wouldn't.

For example, with GOPATH set like so

And after creating some subdirectories
mkdir /home/adg/gocode/{bin,pkg,src}
I can use goinstall to install the github.com/nf/goto web server,
which depends on the github.com/nf/stat package, with
goinstall github.com/nf/goto
This downloads and installs all dependencies (that aren't already
installed) like so

The list elements are already being allocated out of a
single memory buffer. We can drop the Link* pointer
following and the memory it requires, replacing it with
index operations.
The change also keeps a channel from containing a pointer
back into its own allocation block, which would create a
cycle. Blocks involved in cycles are not guaranteed to be
finalized properly, and channels depend on finalizers to
free OS-level locks on some systems. The self-reference
was keeping channels from being garbage collected.
runtime-gdb.py will need to be updated in order to dump
the content of buffered channels with the new data structure.

Since Go code can deadlock, this lets a testsuite driver set a

doc.go contains the details. The short story:
- command line is passed to the binary
- a new flag, -file, is needed to name files
- known flags have the "test." prefix added for convenience.
- gotest-specific flags are trimmed from the command line.
The effect should be that most existing uses are unaffected,
the ability to name files is still present, and it's nicer to use.
The downside is a lot more code in gotest.
Also allow a test to be called just Test.

As a special case, multi-line raw strings (i.e., strings in `` quotes)
were not indented if they were the only token on a line. This heuristic
was meant to improve formatting for multi-line raw strings where sub-
sequent lines are not indented at the level of the surrounding code.
Multiple people have complained about this. Removing the heuristic
again because it makes the formatting more regular, easier to under-
stand, and simplifies the implementation.
