.hgignore cleanup

[Andrew John Hughes]

I've just given the .hgignore file in IcedTea6 a desperately needed
pruning.  For some (presumably outdated) reason, it was using regular
expression matching while most of the actual entries were assuming
glob matches.
With the old version, hg status questioned 27 files in my checkout.
With the new one, it questions 54, including:

? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_EventLoop.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Operation.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Operation_State.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_PulseAudioSourcePort.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_PulseAudioTargetPort.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_CorkListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_Format.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_LatencyUpdateListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_MovedListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_OverflowListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_PlaybackStartedListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_ReadListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_State.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_StateListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_SuspendedListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_UnderflowListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_UpdateTimingInfoListener.h
? pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream_WriteListener.h

which were no doubt dumped there by some old build that decided to
generate them in tree and have been hidden by hg status ever since.

I also took the opportunity to get rid of a number of java files I
assume date back to the old days of encumbrance avoidance.  I was
tempted to do even more, but left some for those funny folks who build
in-tree.... :-(
