This introduces support for selecting which subelement
to unmarshal into a given struct field by providing a

Have to set #defines correctly to get correct value.
Otherwise get a mask for use in implementing WIFSTOPPED(status).

Changed WSTOPPED definition in os because on
OS X WSTOPPED and WUNTRACED have different values
even though they seem to mean the same thing.

The fault was lucky: when it wasn't faulting it was silently
copying a word from some other block and later putting
that same word back.  If some other goroutine had changed
that word of memory in the interim, too bad.

The ARM code was inconsistent about whether the
"argument frame" included the saved LR.  Including it made
some things more regular but mostly just caused confusion
in the places where the regularity broke.  Now the rule
reflects reality: argp is always a pointer to arguments,
never a saved link register.

Renamed struct fields to make meaning clearer.

Running ARM in QEMU, package time's gotest:
  * before: 27/58 failed
  * after: 0/50

This defines crosscall2 in a way that matches that real
definition, and also defines _cgo_allocate and _cgo_panic to
indicate that they are available to be called by code compiled
with gcc.

In this specific package crosscall2 is already defined in a .S
file anyhow.  This avoids a warning about mismatched
alignment.

Introduced a printer mode (pmode) type and corresponding
pmode values which permit easy toggling of the current
printer mode for fine-tuning of layout.

Use the printer mode to disable potential introduction of
line breaks before a closing '}' in composite literals.

Added extra test case. Applied gofmt to src and misc.

Fixes #1365.

Until now, each scan of a file added a new file to the file set.
With this change, a file can be re-scanned using the same *token.File
w/o changing the file set. Eventually this will enable the re-use of
cached source code in godoc (for the fulltext index). At the moment,
source files are read over and over again from disk.

This is the first step in that direction.

When searching for regular expressions such as
".", there are many consecutive matches.
In the generated HTML, combine them instead of
generating a new <span> for each adjacent text
segment highlighting a match.

Massively reduces the size of the generated
HTML in those cases.
