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.

Fixes #115.

2b1133ff86 cmd/cc: change getquoted() to accept whitespaces. 
getquoted() currently checks for whitespaces and returns nil
if it finds one. this prevents us from having go in a path
containing whitespaces, as the #pragma dynld directives are
processed through the said function.

this commit makes getquoted() accept whitespaces, and this is
also needed for solving issue #115.

7763345379 Support for basic try-catch style exception handling. 
Meant as illustration of the Go pattern that is using
goroutines and channels to handle exceptional situations.

Note: There is no need for "Finally" since the
"try block" (the function f supplied to Try)
cannot do a Smalltalk-style non-local return
and terminate the function surrounding Try.

Replaces CL 157083.

bfbb31595b Map support for template.Execute(). 
Allows the developer to pass a map either by itself for
evaluation, or inside a struct. Access to data inside
maps is identical to the current system for structs, ie.

-Psuedocode-

mp map[string]string = {
	"header" : "A fantastic header!",
	"footer" : "A not-so-fantastic footer!",
}
template.Execute(mp)

...can be accessed using {header} and {footer} in
the template. Similarly, for maps inside structs:

type s struct {
	mp map[string]string,
}
s1 = new s
s1.mp["header"] = "A fantastic header!";
template.Execute(s1)

...is accessed using {mp.header}. Multi-maps, ie.
map[string](map[string]string) and maps of structs
containing more maps are unsupported, but then, I'm
not even sure if that's supported by the language.

Map elements can be of any type that can be written
by the formatters. Keys should really only be strings.

Fixes #259.
