When -feature has not been enabled, we were double counting
identical feature warnings that were emitted at the same position.
Normal error reporting only reports the first time a warning
appears at a position; feature warning counter incrementing
should behave the same way.
@hubertp: Fixed .check files that were broken in the original commit.

As seen here.
scala> class A { @deprecated("foo") def a = 1 }
warning: there were 1 deprecation warnings; re-run with -deprecation for details
defined class A
scala> :warnings
<console>:7: warning: @deprecated now takes two arguments; see the scaladoc.
class A { @deprecated("foo") def a = 1 }
^
scala> val x = 5 toString
warning: there were 1 feature warnings; re-run with -feature for details
x: String = 5
scala> :warnings
<console>:7: warning: postfix operator toString should be enabled
by making the implicit value language.postfixOps visible.
This can be achieved by adding the import clause 'import language.postfixOps'
or by setting the compiler option -language:postfixOps.
See the Scala docs for value scala.language.postfixOps for a discussion
why the feature should be explicitly enabled.
val x = 5 toString

Would prefer to bake a little longer, but, scala days.
More elaboration to come.

Hardened the repl against a bunch of erroneous conditions. Added a
:reset command which causes the repl to forget everything you have told
it. Added classloader tracing when repl tracing is enabled. :reset is
not that useful in its current form but it's the precursor to something
more interesting. No review.

Added *.log and build/ to gitignore so partest/ant artifacts don't show
up in our commit messages. Also fixed whitespace issues arising from the
filter-branch history rewrite for git move.

*** Important note for busy commit log skimmers ***
Symbol method "fullName" has been trying to serve the dual role of "how
to print a symbol" and "how to find a class file." It cannot serve both
these roles simultaneously, primarily because of package objects but
other little things as well. Since in the majority of situations we want
the one which corresponds to the idealized scala world, not the grubby
bytecode, I went with that for fullName. When you require the path to a
class (e.g. you are calling Class.forName) you should use javaClassName.
package foo { package object bar { class Bippy } }
If sym is Bippy's symbol, then
sym.fullName == foo.bar.Bippy
sym.javaClassName == foo.bar.package.Bippy
*** End important note ***
There are many situations where we (until now) forewent revealing
everything we knew about a type mismatch. For instance, this isn't very
helpful of scalac (at least in those more common cases where you didn't
define type X on the previous repl line.)
scala> type X = Int
defined type alias X
scala> def f(x: X): Byte = x
<console>:8: error: type mismatch;
found : X
required: Byte
def f(x: X): Byte = x
^
Now it says:
found : X
(which expands to) Int
required: Byte
def f(x: X): Byte = x
^
In addition I rearchitected a number of methods involving:
- finding a symbol's owner
- calculating a symbol's name
- determining whether to print a prefix

The eagerly awaited companion commit to r23622, the surprise hit of last
winter. Singletons now have the singleton type inferred in monomorphic
contexts as well. In english:
scala> object X
defined module X
scala> def f = X
f: X.type
Wait, that's not english. English review by moors.

Enhancing the repl-testing code by turning it into a transcript
producing machine. "Here's some code." "Here's a transcript!" "Good day
to you, sir!" "No, good day to YOU!"
These changes are awesome. Look at the checkfile diffs for god's sake,
they'll make you weep with joy. No review.

I keep seeing huge simplifications available in the repl. Lot of
interesting features have come to town since it was first conceived. In
this commit I give the internal names some tips on aesthetics, and put
each line in its own package like civilized artificial constructs. No
review.

The empty string commit made me hungry to actually know what's in stuff.
Now it prints quotes around a string if it's empty or if either the
first or last character is whitespace. No review.

eliminated the import of ambiguously named classes from e.g.
collection.mutable, obeyed a todo in the parser regarding dropping
lbracket from statement starting tokens. No review.

Fix for the partest task to fail the build when a test fails, and fixes
for 2/3 of the quietly failing tests. I'm not quite sure what to do
about the view ones, it doesn't look like a simple rename is going to
cut it, so: review by odersky.

Reorganizes children a little so they always come back sorted the same
way the pickler does. Taking advantage of -Yfatal-warnings in the test
case. Review by community.

flags on AnyVal from FINAL|SEALED to ABSTRACT|SEALED. This appears
correct and without ill effect, but if anyone spots new anyval oddness
you know where to look.

- MethodTypes now have (params: List[Symbol])
- "copy"-methods for case classes
- the "copy" object in the compiler is now called "treeCopy"

A big yet interim patch emerging from my attempts to centralize common
classloader-related code. As it turns out, not that much of the
patch is directly associated with that. Most of it is cleanup in the
neighborhoods I was visiting, but there are a few new library files
about which I'm open to feedback:
scala/util/control/Exception - lots of exception handling code.
scala/net/Utility - what would be the first file in scala.net.*,
more code to follow if that sounds like a good package idea.
scala/util/ScalaClassLoader - mostly convenience methods right
now, more sophistication to come
Also, this adds a :jar command to the repl which adds a jar to your
classpath and replays the session.

Removed a bunch of now useless 1.4 code, merged
back jvm5-specific partest tests into the
general jvm tests, documentation updates.
