Instead of serving files of the underlying OS file system,
a .zip file may be provided to godoc containing the files
to serve; for instance:

   godoc -http=:6060 -zip=go.zip

using a .zip file created from a clean tree as follows:

   zip -r go.zip $GOROOT

Angle brackets can trigger some browser sniffers, causing

The data race is on newly published Itab nodes, which are
both unsafely published and unsafely acquired. It can
break on IA-32/Intel64 due to compiler optimizations
(most likely not an issue as of now) and on ARM due to
hardware memory access reorderings.

No longer do we generate HTML from it; instead the input
file is already in HTML but has template invocations to
extract programs from other files.
Delete htmlgen, which is no longer needed.

Per the TIS ELF spec, if a PHDR entry is present in the
program header table, it must be part of the memory image of
the program. Failure to do this makes elflint complain, and
causes some tools that manipulate ELF to crash.
