A radical overhaul of the coercion infrastucture
* Core Lint now does full checking of kinds and coercion terms
which picks up kind errors in coercions that were previously
simply not checked for
* Coercion.lhs now provides optCoercion which optimises coercion
terms. It implements all of Dimitrios's rules
* The constructors for coercion terms now make no attempt to be
"smart"; instead we rely solely on the coercion optimiser
* CoercionTyCons in TyCon.lhs always had a "custom" kinding rule
(the coKindFun field of CoercionTyCon) but its type was not
clever enough to do both
(a) *figure out the result kind*, assuming the whole thing
is well-kinded in the first place
(b) *check* the kinds of everything, failing gracefully if
they aren't right.

CoTyConKindChecker

Fix #1185 (RTS part, also needs corresponding change to libraries/base)
GHC.Conc.ensureIOManagerIsRunning now creates an IO manager thread if
one does not exist or has died/exited.
Unfortunately this exposed a problem caused by the fact that we have
two base packages, and hence two IO managers, in GHCi: see NOTE
[io-manager-ghci] in rts/Linker.c. The workaround can go away if/when
we switch to a dynamically linked GHCi.

GhciMonad.resume should restore the program's argv and progname
I discovered that single-stepping over getArgs gave the wrong answer
sometimes, because we were forgetting to set the program's argv and
progname when resuming at a breakpoint.
Test is ghci.debugger/scripts/getargs.script.

Refactor package installation
There is now less makefile code duplication.
Also, stage2 packages are registered after GHC, which is important as
they might depend on the ghc package (as dph now does).
