Minux removed the use of SRPC in 003dccfa, but the SRPC name service
code was left in the tree. SRPC was removed in pepper_42 making the
code, which ran on startup, fail, even though it was not used.
Removing srpc_nacl.go for a total diff of -822 lines has got to count
as one of the easiest nacl fixes we've had to date.

Issue 6754 reports that Go bzip2 Decode function is much slower
(about 2.5x in go1.5) than the Python equivalent (which is
actually just a wrapper around the usual C library) on random data.
Profiling the code shows that half a dozen of CMP instructions in a
tight loop are responsibile for most of the execution time.
This patch reduces the number of branches of the loop, greatly
improving performance on random data and speeding up decoding of
real data.

I've run some benchmark comparing Go bzip2 implementation with the
usual Linux bzip2 command (which is written in C). On my machine
this patch brings go1.5
from ~2.26x to ~1.50x of bzip2 time (on 64MB random data)
from ~1.70x to ~1.50x of bzip2 time (on 100MB english text)
from ~2.00x to ~1.88x of bzip2 time (on 64MB /dev/zero data)

For ARM machines, the assembler supports list of registers
operands such as [R1,R2].
A list missing a ']' results in the parser issuing many errors
and consuming all the tokens. At EOF (i.e. end of the line),
it still loops.
Normally, a counter is maintained to make sure the parser
stops after 10 errors. However, multiple errors occuring on the
same line are simply ignored. Only the first one is reported.
At most one error per line is accounted.
Missing ']' in a register list therefore results in an
infinite loop.
Fixed the parser by explicitly checking for ']' to interrupt
this loops
In the operand tests, also fixed a wrong entry which I think was
not set on purpose (but still led to a successful result).

Previously t.zero always pointed to runtime.zerovalue. Change the hashmap code
to always return a runtime pointer directly, and change that pointer to point
to a larger buffer if one is needed.
(It might be better to only copy from the pointer returned by the mapaccess
functions when the value type is small enough and have the compiler insert
explicit zeroing for larger value types, but I tried and failed to do this).
This removes all uses of the zero field of the type data; the field itself can
be removed in a separate change.

A comparison of the form l == r where l is an interface and r is
concrete performs a type assertion on l to convert it to r's type.
However, the compiler fails to zero the temporary where the result of
the type assertion is written, so if the type is a pointer type and a
stack scan occurs while in the type assertion, it may see an invalid
pointer on the stack.
Fix this by zeroing the temporary. This is equivalent to the fix for
type switches from c4092ac.
