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.

  * add runtime sliceslice1 for x[lo:]
  * remove runtime arraytoslice, rewriting &arr into arr[0:len(arr)].
  * port cgen_inline into 8g, 5g.

  * reverse-complement: port C algorithm to Go
	saves 30% on my MacBook Pro and makes it a fairer comparison.
  * test reverse-complement with and without GC (another 15%)
  * revise timing.sh to work on more systems
  * avoid two glibcisms in fasta.c

once more with feeling.

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.

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.
