Example use: godoc -path=/home/user1:/home/build/foo -http=:6666
will start a local godoc that maps urls starting with /pkg/user1 or
/pkg/foo to the respective roots specified in the path.
Missing: Handling of overlapping package directories, multiple
packages per directory.

printing a bad type.
Add test for String method with named basic types.

because free needs to mark the block as freed to
coordinate with the garbage collector.
(in C++ free can blindly put the block on the free list,
no questions asked, so the cache saves some work.)

not trying to be secure, just not repetitive
(sending with the same id repeatedly makes
some resolvers stop replying.)
eventually we'll replace this with linking against
the system's native resolver.

* specialize sweepspan as sweepspan0 and sweepspan1.
* in sweepspan1, inline "free" to avoid expensive mlookup.

Added tests and benchmarks for Exp2 (special cases same
as Exp). Log1p also enhances speed of inverse hyperbolics.

apparently some versions of GNU make cannot
handle the %: %.$O rule. i don't understand why
and don't care enough to find out.

Add functions, tests and benchmarks. Fix typos in comments
in expm1 and hypot_386. Fix Acosh domain error in benchmark

Averaged times (in microseconds) for drawing an 800x600 rectangle
are listed below. The summary is: around a 100x improvement.
draw.Draw call times were typically linear in the number of pixels
touched (i.e. drawing an 800x600 rectangle took 100x as much time as
drawing an 80x60 rectangle).
Before this change, there was only the general-but-slow code path.
When drawing any src with a 50%-opaque mask: 237300 us
When drawing any src with a nil mask: 50100 us
After this change, the 50%-opaque mask case is unchanged.
For an *image.RGBA dst and nil mask and...
...a uniform color (i.e. an image.ColorImage) src: 282 us
...another *image.RGBA src: 615 us.
For the curious, an intermediate implementation detected the special
cases but used simple nested for loops instead of the built-in copy
function. The respective times (compared to 282 and 615 for the
final implementation, or 50100 for the original) were 3110 and 3573.
Times were measured with 8g/8l on my laptop. I haven't tried gccgo
or other architectures.
