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.

Also adds some tests for Issue 900 which was the reason
the current URL parsing is broken.  (the previous fix
was wrong)

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.

This implements the algorithm qsufsort using the sort package
as a sorting primitive. Its worst-case performance is O(N*log(N)), and it
uses only an additional slice of N ints of memory during creation.

error is needed by all the OpenPGP packages as they return a shared
family of error types.

armor implements OpenPGP armoring. It's very like PEM except:
  a) it includes a CRC24 checksum
  b) PEM values are small (a few KB) and so encoding/pem assumes that
     they fit in memory. Armored data can be very large and so this
     package presents a streaming interface.

The code was (as annotated in the source code) adopted from Tom's
LibCrypt (public domain code, [1]). It was neither optimised for speed
nor were any security features added.

I missed that environment is used during runtime setup,
well before go init() functions run. Implemented os-dependent
runtime.goenvs functions to allow for different unix, plan9 and
windows versions of environment discovery.

A few system call numbers on x86 Linux are
defined in terms of a previous definition,

e.g.,
	#define __NR_timer_create	259
	#define __NR_timer_settime	(__NR_timer_create+1)
	...
	#define __NR_mq_open		277
	#define __NR_mq_unlink		(__NR_mq_open+1)

This change assumes the numbers are sorted
sequentially in the input file.
