4f445d2744 big: reduce the number of allocations 
There was a bug in makeN that caused lots of unnecessary
allocations.  Fixing this exposed a few bugs in other
functions which worked when makeN allocated a new slice, but
failed when it simply resized an existing slice.  The result
is a pretty big performance improvement.  When running
pidigits, here were the numbers I got on amd64:

Before this change:
pidigits 10000
        gcc -O2 pidigits.c -lgmp        2.09u 0.02s 2.11r
        gc pidigits     12.68u 0.04s 12.72r
        gc_B pidigits   12.71u 0.03s 12.75r

After:
pidigits 10000
        gcc -O2 pidigits.c -lgmp        2.09u 0.00s 2.10r
        gc pidigits     6.82u 0.00s 6.85r
        gc_B pidigits   6.55u 0.01s 6.59r

76cbbc8a95 big: Add Lsh and Value; convert pidigits to use big 
This yields a pretty significant performance boost to pidigits and there are still some improvements to be made. Here are my numbers:

amd64 w/ bignum:
pidigits 10000
        gcc -O2 pidigits.c -lgmp        2.10u 0.00s 2.10r
        gc pidigits     22.92u 0.02s 22.97r
        gc_B pidigits   22.62u 0.00s 22.65r

amd64 w/ big:
pidigits 10000
        gcc -O2 pidigits.c -lgmp        2.09u 0.02s 2.11r
        gc pidigits     12.68u 0.04s 12.72r
        gc_B pidigits   12.71u 0.03s 12.75r

386 w/ bignum:
pidigits 10000
        gcc -O2 pidigits.c -lgmp        2.09u 0.00s 2.09r
        gc pidigits     44.30u 0.01s 44.35r
        gc_B pidigits   44.29u 0.03s 44.35r

386 w/ big:
pidigits 10000
        gcc -O2 pidigits.c -lgmp        2.10u 0.00s 2.10r
        gc pidigits     22.70u 0.06s 22.79r
        gc_B pidigits   22.80u 0.09s 22.91r

3ffbd57b94 syscall: match linux Setsid function signature to darwin 
SETSID does return an errno - any reason why it has been done this
way in zsyscall_linux_* ? Otherwise it should be the same as darwin.

From SETSID(2) on my Linux box:

ERRORS
       On error, -1 is returned, and errno is set.

Fixes #730

3cfa2c3ddf json: scanner, Compact, Indent, and tests 
This is the first of probably four separate CLs
for the new implementation of the json package.

The scanner is the core of the new implementation.
The other CLs would be the new decoder,
the new encoder, and support for JSON streams.

fffac8072e "godoc -src pkg_name" excludes duplicates entries 
$ godoc xml | grep Copy\(\)
func (c CharData) Copy() CharData
func (c Comment) Copy() Comment

func (c CharData) Copy() CharData
--------------------------------------------
$ godoc -src xml Copy
func (c CharData) Copy() CharData { return CharData(makeCopy(c)) }
--------------------------------------------
The command "godoc -src pkg_name" should output the interface of the named package, but it excludes all duplicate entries. Also the command "godoc -src pkg_name method_name" will output the source code only for one method even if there are more of them with the same name in the same package. This patch set fixes this issue.

1ab15fac22 fmt format verb %b bug 
fmt.Printf("%b", int8(-1)) prints 64 ones instead of 8.
This happens only for signed integers (int8, in16 and int32). I guess it's because of the way the conversion between integer types works. From go spec: "Conversions between integer types. If the value is a signed quantity, it is sign extended to implicit infinite precision ....". And there are several conversions to int64 and uint64 in the fmt package. This pathch solves only half of the problem. On a 32 bit system, an fmt.Printf("%b", int(-1)) should still print 64 ones.
