68b4255a96 runtime: ,s/[a-zA-Z0-9_]+/runtime·&/g, almost 
Prefix all external symbols in runtime by runtime·,
to avoid conflicts with possible symbols of the same
name in linked-in C libraries.  The obvious conflicts
are printf, malloc, and free, but hide everything to
avoid future pain.

The symbols left alone are:

	** known to cgo **
	_cgo_free
	_cgo_malloc
	libcgo_thread_start
	initcgo
	ncgocall

	** known to linker **
	_rt0_$GOARCH
	_rt0_$GOARCH_$GOOS
	text
	etext
	data
	end
	pclntab
	epclntab
	symtab
	esymtab

	** known to C compiler **
	_divv
	_modv
	_div64by32
	etc (arch specific)

Tested on darwin/386, darwin/amd64, linux/386, linux/amd64.

Built (but not tested) for freebsd/386, freebsd/amd64, linux/arm, windows/386.

d9c989fa25 various: avoid %ld etc 
The Plan 9 tools assume that long is 32 bits.
We converted all instances of long to int32 when
importing the code but missed the print formats.
Because int32 is always int on the compilers we use,
it is never correct to use %lux, %ld, etc.  Convert to %ux, %d, etc.

(It matters because on 64-bit gcc, long is 64 bits,
so we were printing 32-bit quantities with 64-bit formats.)

	date:        Thu Jun 03 16:55:50 2010 -0700

	description:
	go spec: Base comparison compatibility on assignment compatibility.

	Specifically:
	- Simplified definition of comparison compatibility and folded into
	  section on comparison operators since it's only used there.

	This is a small language change/cleanup. As a consequence:
	- An interface value may now be compared against a non-interface value.
	- Channels with opposite directions cannot be compared directly anymore
	  (per discussion with rsc).

4d903504b3 runtime: special case copy, equal for one-word interface values 
Based on the observation that a great number of the types that
are copied or compared in interfaces, maps, and channels are
word-sized, this uses specialized copy and equality functions
for them that use a word instead of 4 or 8 bytes. Seems to yield
0-6% improvements in performance in the benchmarks I've run.
For example, with the regexp benchmarks:

Before:
regexp.BenchmarkLiteral   500000       3.26 µs/op
regexp.BenchmarkNotLiteral    100000      13.67 µs/op
regexp.BenchmarkMatchClass    100000      18.72 µs/op
regexp.BenchmarkMatchClass_InRange    100000      20.04 µs/op
regexp.BenchmarkReplaceAll    100000      27.85 µs/op

After:
regexp.BenchmarkLiteral   500000       3.11 µs/op
regexp.BenchmarkNotLiteral    200000      13.29 µs/op
regexp.BenchmarkMatchClass    100000      17.65 µs/op
regexp.BenchmarkMatchClass_InRange    100000      18.49 µs/op
regexp.BenchmarkReplaceAll    100000      26.34 µs/op

758f2bc556 eliminate the package global name space assumption in object files 
5g/6g/8g: add import statements to export metadata, mapping package path to package name.
	recognize "" as the path of the package in export metadata.
	use "" as the path of the package in object symbol names.

5c/6c/8c, 5a/6a/8a: rewrite leading . to "". so that ·Sin means Sin in this package.

5l/6l/8l: rewrite "" in symbol names as object files are read.

gotest: handle new symbol names.

gopack: handle new import lines in export metadata.

Collectively, these changes eliminate the assumption of a global
name space in the object file formats.  Higher level pieces such as
reflect and the computation of type hashes still depend on the
assumption; we're not done yet.

                  Use -oldparser to parse the old syntax,
                  use -oldprinter to print the old syntax.

               2) Change default gofmt formatting settings
                  to use tabs for indentation only and to use
                  spaces for alignment. This will make the code
                  alignment insensitive to an editor's tabwidth.

                  Use -spaces=false to use tabs for alignment.

               3) Manually changed src/exp/parser/parser_test.go
                  so that it doesn't try to parse the parser's
                  source files using the old syntax (they have

6fc820729e go: makes it build for the case $GOROOT has whitespaces 
the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.

this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.

d515063588 better handling of mistaken top-level variable 
references during the parsing of :=.  the base
problem is that when reading

	a,b,c,d

the parser makes those refer to existing variables,
which might create a few stub top-level ones
for undefined names, but then if a := is the next
token, we need to undo those stubs.

this was causing problems in multifile packages
in which one file used a := variable named rpc
and the other imported a package named rpc.

9346c6d901 make every func literal expression allocate, 
so that == on func means that the
functions originated in the same
execution of a func literal or definition.

before, there was an inconsistency:

	func() {x++} != func() {x++}

but

	func() {} == func() {}

this CL makes the second case != too,
just like

	make(map[int]int) != make(map[int]int)
