In preparation for work on progressive loading, update the exception
handling scheme slightly.
Until now, exceptions (as thrown with fz_throw, and caught with
fz_try/fz_catch) have merely had an informative string. They have
never had anything that can be compared to see if an error is of
a particular type.
We now introduce error codes; when we fz_throw, we now always
give an error code, and can optionally (using fz_throw_message)
give both an error code and an informative string.
When we fz_rethrow from within a fz_catch, both the error code and
the error message is maintained. Using fz_rethrow_message we can
'improve' the error message, but the code is maintained.
The error message can be read out using fz_caught_message() and the
error code can be read as fz_caught().
Currently we only define a 'generic' error. This will expand in future
versions to include other error types that may be tested for.

Attempt to separate public API from internal functions.

In error cases, ensure we free objects correctly. Thanks to Zeniko
for finding the problems (and many of the solutions!)

Rather than passing a stream to a close function, just pass context
and state - that's all that is required. This enables us to
call close to cleanup neatly if the stream fails to allocate.

The new fz_malloc_struct(A,B) macro allocates sizeof(B) bytes using
fz_malloc, and then passes the resultant pointer to Memento_label
to label it with "B".
This costs nothing in non-memento builds, but gives much nicer
listings of leaked blocks when memento is enabled.

Huge pervasive change to lots of files, adding a context for exception
handling and allocation.
In time we'll move more statics into there.
Also fix some for(i = 0; i < function(...); i++) calls.

Import exception handling code from WSS, modified to fit into the
fitz world.
With this code we have 'real' fz_try/fz_catch/fz_rethrow functions,
handling a fz_except type. We therefore rename the existing fz_throw/
fz_catch/fz_rethrow to be fz_error_make/fz_error_handle/fz_error_note.
We don't actually use fz_try/fz_catch/fz_rethrow yet...

The run-together words are dead! Long live the underscores!
The postscript inspired naming convention of using all run-together
words has served us well, but it is now time for more readable code.
In this commit I have also added the sed script, rename.sed, that I used
to convert the source. Use it on your patches and application code.
