windows cmd.exe can't show utf-8 correctly basically.
chcp 65001 may make it show, but most people don't have fonts which can
show it.

A "gccgoprefix" flag is added and used by the go tool,
to mirror the -fgo-prefix flag for gccgo, whose value
is required to know how to access functions from C.

Trying to export Go methods or unexported Go functions
will not work.

Also fix go test on "main" packages.

Updates #2313.

Robert suggested not reporting errors until the end of the output.
which I'd also like to do, but errPrintedOutput makes that a bigger
change than I want to do before Go 1.  This change should at least
remove the confusion we had.

This function uses 48-byte of precious non-split stack for every callback
function, and without this CL, it can easily overflow the non-split stack.

Currently, ftdetect/gofiletype.vim set fileencodings to open the file as
utf-8 encoding event if the file does not contain multibyte characters.
But fileencodings is global option.

$ vim foo.txt
:set fileencodings
utf-8,ucs-bom,cp932

$ vim foo.go
:set fileencodings
utf-8

This change restore fileencodings before opening the file.
Also added specify fileformats=unix.
