Simplifies coding.

Limited testing seems to suggest that the only thing stopping the MuPDF
library building on metro seems to be the use of winsock.h.

Previously if the lookup table was full and no clear code appeared the
decoder would try to add more entries to the table. However the table
is of fixed size (4096 entries) so it would write outside the table.
Fix this by detecting when the lookup table is full and a clear code
ought to appear. At this point the decoder will now treat and process
any code as a clear code.
For valid documents this will never happen, for invalid documents this
means risking that succeeding codes may be misinterpreted and that the
decoded data will be incorrect, this case should be handled by the
consumer of the data though.
Fixes bug 693306.

Use a "magic" string for filetype detection: filename or mime-type.

Mountian Lion causes various different warnings to be given,
possibly because a change to clang by default. Fix them here.

This brings in Memento_breakOnRealloc and Memento_breakOnFree along with
some other small tweaks.

Adjust macros to make them reusable with 64-bit arithmetic.
Rename functions to avoid future namespace collisions.

Rather than specifically checking for the nesting getting too deep and
hence throwing an error, the error handling should do this for itself.
Make it so that we spot the depth being too great in the fz_try() and
throw to the fz_catch().

Previously the jpeg decoder state had to be fully initialized in order
to be freed when the jpeg decoder is closed, e.g. due to an error. Now,
signal that the decode state is initialized earlier, even if the state
has not been fully initialized, so that the state is freed.

Thanks to Zeniko for pointing out the inconsistency.

Thanks to Zeniko for pointing out this fix.

Previously we would run out of error stacks in the context and fail abruptly.
Now, throw an exception and hope for the best. At least this plugs any memory
leaks.

Acrobat seems to cope, we should too. See normal_439.pdf for an
example.

Instead of using macros for min/max/abs/clamp, we move to using
inline functions. These are more typesafe, and should produce
equivalent code on compilers that support inline (i.e. pretty much
everything we care about these days).
People can always do their own macro versions if they prefer.

normal_994.pdf SEGVs due to a negative length. Simple fix to treat
negative length streams as 0 length.

When writing few enough bits that they would fit into the 'spare' bits
in the last byte, I was failing to update the buffer.
Also, I was failing to grow the buffer enough, and calculating the
wrong number of bits left over in various places.
Both fixed here. Thanks to Robert Jedrzejczyk and Sebras!

The putcomponent function assumes the function has been cleared.
Simple fix to clear bytes at the start of each scanline.

When calculating the displaylist node rectangles, we were failing
to adjust for linewidth/mitrewidth etc. This could result in glyphs
being clipped; see normal_130.pdf for example.

This solves the normal_87.pdf rendering issues.

Remove unused variable, silencing compiler warning.
No need to initialize variables twice.
Remove initialization of unread variable.
Remove unnecessary check for NULL.
Close output file upon error in cmapdump.
