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.

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.

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.

* reverse-complement: port C algorithm to Go

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.

archive/tar: Make Reader and Writer more closely follow io.Reader and io.Writer interfaces
There's no functional change here. io gives the Read and Write methods byte slice arguments, but tar called them uint8. It's the same thing, but I think this is clearer and it matches what other packages do.

two easy optimizations for regexp:
1) if char class contains a single character, make it a single character.
(this is used to quote, e.g. [.] rather than \.
2) if regexp begins with ordinary text substring, use plain string match to start engine

add bytes.IndexByte; common case we can make fast later.
also pick off the special case in strings.Index. don't want strings.IndexByte
because the call site will very rarely need to allocate and we can handle the
test in the code itself. bytes.IndexByte can avoid a common allocation.

net: remove race condition on Close.
Previously a netFd could be queued for reading/writing in the channel,
but close(2)'ed before pollServer got to it. In this case, the kernel
would consider the descriptor closed and the attempt to add it to the
epoll set would fail and panic.
This patch makes Close a roundtrip to the pollServer, although the
actual close(2) still occurs elsewhere to avoid blocking the
pollServer.
