Remove build.number.maven

I can't find any justification for having this information
in both build.number and build.number.maven.

They have drifted apart on the 2.10.x branch, although that
doesn't matter because build.number is correct, and loaded first,
and Ant properties are write-once.

I'm assuming that the Ant tasks in src/build/pack.xml are only
invoked through the <antcall>-s in ./build.xml.

Here's a test of that from the 2.10.x branch:

	% cat build.number
	#Tue Sep 11 19:21:09 CEST 2007
	version.major=2
	version.minor=10
	version.patch=3
	# This is the -N part of a version.  if it's 0, it's dropped from maven versions.
	version.bnum=0

	# Note: To build a release run ant with -Dbuild.release=true
	# To build an RC, run ant with -Dmaven.version.suffix=-RCN

	% cat build.number.maven
	version.major=2
	version.minor=10
	version.patch=0

	% git diff

Notice how the stale `version.patch=0` in build.number.maven is
ignored.
SI-7841 Remove commented out AnyRef specialization from Function{0,1}.

In a sign of decreased optimism about that facility.
SI-7847 Static forwarders for case apply/unapply

These were excluded in f901816b3f because at the time they
were compiler fiction and translated to calls to the case
class constructor or accessors.

But since they are now bona-fide methods (albeit still occasionally
bypassed as an optimization), we can expose them conveniently to our
Java brethren.

The cut-and-pastiness of GenBCode starts to hinder maintenance.
Here's a report of further duplication that we have to fix up
post haste: https://gist.github.com/retronym/6334389
SI-7841 Remove AnyRef specialization from AbstractPartialFunction

This was missed in cc3badae1

Compatibility classes for formerly specialized variants used
by Scalacheck have been added as a stopgap measure until we
publish the next milestone.
SI-7841 More robust unspecialization of names

Names like `T1$sp`, which can arise from `AnyRef` specialization,
were leading to negative length Names if they ever passed through
`unspecializedName` or `splitSpecializedName`. This code path was
touched when printing the tree of a certain AnyRef specialized
classes after specialization, such as `AbstractPartialFunction`
(which had such specialization until a few commits ago.)

This commit handles that case correctly, and generally hardens
against unexpected names, which could pop up from third party
classes.

The documentation for `splitSpecializedName` transposed the
class and method specializations. The things you discover
when you turn examples in documentation in to test cases!

In addition, we now require non-negative length and offset in
`newTermName`

Longer timeout for repl test.

15 seconds is crazy aggressive. I have fast hardware and it's still
really easy for a test to take to fifteen seconds under load.

Silence pos/t3960's -Ycheck output.

Someday someone will have to straighten out where output goes.
Clearly under current conditions, Console.err is not a good place.
I rerouted through unit.warning so the output will be swallowed

SI-7853 An unsatisfying fix regression in explicit outer

The attempt to placate pos/t4970.scala in 55c6fd4 roused another
dragon.

We've got two levers here: the type of the symbol of the outer
accessor, and the type of its DefDef.

They have been historically out of sync due to the vaguaries of
finalResultType (which is far less vague since 671e6e03c7), but
the finicky operation of ExplicitOuter now has a hard time when
we try to bring them into line.

This stuff is notoriously difficult to understand because the
trees you see from `-Xprint` show a tpt derived from the method
symbol's info, and discards the actual tpt in the tree.

Rather than letting `DefDef(acc)` call `TypeTree(sym)` and use
`sym.tpe_*.finalResultType`, this commit computes the member type
of the accessor from the current class and explicitly uses that as
the return type of the outer accessor def.

We should try to push this a little deeper. I tried to put it into
`def TypeTree`, but that broke, among others,
run/concurrent-stream.scala. Maybe `def DefDef` and `def ValDef`?

But a localised fix is the right start as it addresses the regression
in a minimal fashion to get the IDE building again.
SI-7853 A less ad-hoc place to call memberType

Rather than localizing the fix to the outerAccessor, this
commit pushed the call to `memberType` into *all* usages of
`newValDef` and `newDefDef`.

The TPT of `applyOrElse` in synthetized partial functions must
be set explicitly to pass the pos/t7853-partial-function.scala.
Otherwise, the as-seen-from ends up cloning the type parameter
`B1` of `applyOrElse` as it transforms (questionably)
its bound from `List[Int @unchecked]` to `List[Int]`.

Partial Function synthesis was already a delicate area, and this
makes things more explicit which could be counted as an improvement.
Cull extraneous whitespace.

One last flurry with the broom before I leave you slobs to code
in your own filth. Eliminated all the trailing whitespace I
could manage, with special prejudice reserved for the test cases
which depended on the preservation of trailing whitespace.

Was reminded I cannot figure out how to eliminate the trailing
space on the "scala> " prompt in repl transcripts. At least
reduced the number of such empty prompts by trimming transcript
code on the way in.

Routed ConsoleReporter's "printMessage" through a trailing
whitespace stripping method which might help futureproof
against the future of whitespace diseases. Deleted the up-to-40
lines of trailing whitespace found in various library files.

It seems like only yesterday we performed whitespace surgery
on the whole repo. Clearly it doesn't stick very well. I suggest
it would work better to enforce a few requirements on the way in.

Type housekeeping.

Moved ListOfNil somewhere more generally accessible. No
reason the compiler should hoard it for itself. Flitted
to a few locations with constructs like ".head.head" and
".tail.head" looking for code which could be rewritten. Found
some, admittedly not always making use of ListOfNil.

Made overdue moves of ConstantType(Constant(true|false|null))
to vals in Definitions.
