HotSpot just got Hotter - IcedTea6 support for latest HotSpot

[Andrew John Hughes]

I've added two new options to IcedTea6:

--with-hotspot-build=x
--with-hotspot-src-zip=<path>

When --with-hotspot-build is given, the build will attempt to use the
specified version of HotSpot.  The version numbers are contained in
the new file hotspot.map which maps build numbers to changesets. The
build number is also used in the name of some patches so correct
versions are applied.  This may yet be simplified to just do old/new.
Feedback welcome.

With this patch, the build defaults to using hs14.0b08 (the current
OJ7 HotSpot) and will download this from hg.openjdk.java.net unless
--with-hotspot-src-zip is used.  --with-hotspot-build=original or
--without-hotspot-build will disable this and return to the existing
hs10.0b19 version.

I've not yet checked that Zero still works with this, so for now the
tree is available from http://fuseyism.com/hg/icedtea6 instead.
Building this gives:

java version "1.6.0_0"
IcedTea6 1.4-r990fb5e4f060 Runtime Environment (build 1.6.0_0-b13)
OpenJDK 64-Bit Server VM (build 14.0-b08, mixed mode)
