- Changed the Scan API semantics slightly:
The token literal string is only returned
if the token is a literal, comment, semicolon,
or illegal character. In all other cases, the
token literal value is determined by the token
value.

Clients that care about the token literal value
when not present can always use the following
piece of code:

pos, tok, lit := scanner.Scan()
if lit == "" {
   lit = tok.String()
}

- Changed token.Lookup API to use a string instead
of a []byte argument.

- Both these changes were long-standing TODOs.

- Added BenchmarkScan.

This change permits a faster implementation of Scan
with much fewer string creations:

benchmark                old ns/op    new ns/op    delta
scanner.BenchmarkScan        74404        61457  -17.40%

This is a relic from the times when we switched
to automatic semicolon insertion. It's still use-
ful to have a non-exported switch for testing.

1) Include Szabolcs Nagy's patch which adds serialisation for more
   signature subpackets.
2) Include Szabolcs Nagy's patch which adds functions for making DSA
   keys.
3) Make the random io.Reader an argument to the low-level signature
   functions rather than having them use crypto/rand.
4) Rename crypto/openpgp/error to crypto/openpgp/errors so that it
   doesn't clash with the new error type.

on the benchmark.

What package image currently provides is a larger image consisting
of many copies of a smaller image.

More generally, a tiled image could be a quilt consisting of different
smaller images (like Google Maps), or a technique to view a portion of
enormous images without requiring the whole thing in memory.

This richer construct might not ever belong in the standard library (and
is definitely out of scope for Go 1), but I would like the option for
image.Tiled to be its name.

flag -l means: inlining on, -ll inline with early typecheck
-l lazily typechecks imports on use and re-export, nicer for debugging
-lm produces output suitable for errchk tests, repeated -mm... increases inl.c's verbosity
export processed constants, instead of originals
outparams get ->inlvar too, and initialized to zero
fix shared rlist bug, that lead to typecheck messing up the patched tree
properly handle non-method calls to methods T.meth(t, a...)
removed embryonic code to handle closures in inlined bodies
also inline calls inside closures (todo: move from phase 6b to 4)
