Use a bytes.Buffer in log writing instead of string concatenation.
Should reduce the number of allocations significantly.

New logging interface simplifies and generalizes.
1) Loggers now have only one output.
2) log.Stdout, Stderr, Crash and friends are gone.
Logging is now always to standard error by default.
3) log.Panic* replaces log.Crash*.
4) Exiting and panicking are not part of the logger's state; instead
the functions Exit* and Panic* simply call Exit or panic after
printing.
5) There is now one 'standard logger'. Instead of calling Stderr,
use Print etc. There are now triples, by analogy with fmt:
Print, Println, Printf
What was log.Stderr is now best represented by log.Println,
since there are now separate Print and Println functions
(and methods).
6) New functions SetOutput, SetFlags, and SetPrefix allow global
editing of the standard logger's properties. This is new
functionality. For instance, one can call
log.SetFlags(log.Lshortfile|log.Ltime|log.Lmicroseconds)
to get all logging output to show file name, line number, and
time stamp.
In short, for most purposes
log.Stderr -> log.Println or log.Print
log.Stderrf -> log.Printf
log.Crash -> log.Panicln or log.Panic
log.Crashf -> log.Panicf
log.Exit -> log.Exitln or log.Exit
log.Exitf -> log.Exitf (no change)
This has a slight breakage: since loggers now write only to one
output, existing calls to log.New() need to delete the second argument.
Also, custom loggers with exit or panic properties will need to be
reworked.
All package code updated to new interface.
The test has been reworked somewhat.
The old interface will be removed after the new release.
For now, its elements are marked 'deprecated' in their comments.
Fixes#1184.

1) hack regalloc to leave R9 (m) and R10 (g) alone.
the real fix is tricker, but this gets us running
2) fix up the few places in the package sources that
the shortage of registers affects, by simplifying
some expressions.
all of this should be reverted when the right fix is in.
Fixes#1084.

log: add test of Caller
New regexp in log test is picky and will require some
maintenance, but it catches off-by-one mistakes too.

parsing and printing to new syntax.
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
new syntax now).
4) gofmt -w src misc test/bench
3rd set of files.

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.
Fixes#115.
