Do not reserve virtual address space.
Instead, assume it will be there when we need it,
and crash loudly if that assumption is violated.
Reserving the address space gets charged to
ulimit -v, which exceeds commonly set limits.

Neither gofmt nor godoc are making use of a Styler (for
token-specific formatting) anymore. Stylers interacted in complicated
ways with HTML-escaping which was why the printer needed an HTML mode
in the first place.

godoc now uses a more powerful and general text formatting
function that does HTML escaping, text selection, and can
handle token-specific formatting if so desired (currently
used only for comments).

As a consequence, cleaned up uses of go/printer in godoc;
simplified the various write utility functions, and also
removed the need for the "html" template format (in favor of
html-esc which now does the same and is used more pervasively).

Applied gofmt -w src misc to verify no changes occured,
and tested godoc manually.

There should be no visible changes except that (type) code
snippets presented for godoc package documentation now
uses the same formatting as for general source code and
thus comments get the comment-specific color here as well
(not the case at the moment).

(TODO: godoc needs a good automatic test suite).

Structs defined in C as containing a field with
an enum type are currently translated to Go as
a struct with an unsigned integer field, even if
some of the values contained in the enum are
negative.

This modification takes in consideration the values
defined in the enum, and conditionally defines the
Go type as signed if necessary.

The logic introduced was tested with gcc, which
will increase the type size if it contains both
negative numbers and values greater than 2^b/2-1,
and refuses to compile values which would be
problematic (2^64-1, but in fact the ISO C
restricts the range to the size of int).

Currently, when an importer closes the connection, the exporter gives an
error message 'netchan export: error decoding client header:EOF'.  This
change causes the exporter to look for an EOF during the parse of the
header, and silences the log message in that case.

The logic introduced to avoid running cgo when
introducing _cgo_flags is faulty.  My goal was
to handle it with the following statement:

    -include _cgo_flags

The dash tells make to ignore errors if it can't
include the file.

What I missed, though, was the fact that it
*will* attempt to build the file if it knows
how.

This change will introduce the originally
intended semantics of not attempting to build
the file before necessary.

Many recently issued certificates are chained: there's one or more
intermediate certificates between the host certificate and the root CA
certificate. This change causes the code to load any number of
certificates from the certificate file. This matches the behaviour of
