MHEG: Optimise display update
This patch optimises the MHEG drawing functions and centralises the
function to scale between MHEG coordinates and the OSD.  It also
replaces floating point arithmetic with simple integer ops.

Author:    Lawrence Rust <lvr at softsystem.co.uk> at Tue, 28 Feb 2012 10:26:28 +0100

MHEG: Fix race condition when restarting the DSMCC after a channel change
When a channel change occurs, the DSMCC file cache must be emptied
so that a consistent filesystem is rebuilt from the new carousel.
MHIContext::Restart, which flushes the cache, is called from TV::ITVRestartv
when the channel or card is changed,  However, the ringbuffer continues
to deliver packets from the old stream for a short period after the
change.  This can produce an invalid file structure which can result
in missing text pages or a failure to start the MHEG app.

This change clears the filesystem cache when a NetBootInfo descriptor
is presented in the PMT, which only occurs after the new stream has started.

MHEG: Serialise accesses to the MHEG engine
Fix race conditions in the MHEG engine that can occur when delivering
asynchronous engine events during restart and stream start/stop.

Fix race conditions in the DSM carousel which can result in page loading
timeouts.

freemheg: Fix error handling during Launch
If a Launch fails then either:
- a NULL dereference can occur
- or the MHEG engine can be left without an executing program.

freemheg: Support bitmap backgrounds used by BBC/Freesat
Add support for bitmaps with a content hook of type 5 which are
transmitted by the BBC on FreeSat & FreeView.

Type 5 bitmaps are identical to type 2, an MPEG I-frame, but are intended
to be used as a background onto which the MHEG content and video are rendered.

At present when using the BBC 'Red button' service the background is all
black, missing the background image and red/green/yellow key legend
present on all other STB implementations.

dsmcc: Prevent a potential SEGV by reading beyond end of buffer
Add a test to Dsmcc::ProcessSection to detect if the section length field
is greater than the actual buffer length.  This prevents the CRC
calculation from reading beyond the buffer and causing a SEGV.

Replace the empty path check in MHEngine::RequestExternalContent() which was removed by the iPlayer patches. This may be causing a segfault reported on IRC
