Instead of extracting information from the X509 certificate chain in
the fetcher the entire chain is propagated in Distinguished Encoding
Rules (DER) format.
This allows all the information contained in a certificate chain to be
retained which can subsequently be presented to the user
extend the browser window callback table with a miscallaneous event
entry. This is used to replace all browser window callbacks which
take no parameters.
This reduces the API surface from seven separate calls to a single
call with an enumeration which may be readily extended.
The initial implementation in the frontends simply calls the original
implementations to reduce scope for errors.
We now handle authentication requests via an `about:` page
which presents a nice form built into the browser window.
In order to do this, we add internal navigation as a concept
to the browser window and we strip the 401login support from all
frontends except monkey.
The 401login callback is now intended for password safe type support
rather than an immediately interactive prompt.

the reformat callback was completely unecessary and implementations
appeared potentialy buggy. This rationalises the API and reduces the
number of operations a frontend must provide.
change all the frontends to provide the warning callback in the
miscelaneous table instead of using the warn_user function.
Changing all the warn_user callsites still requires completion.
When the operations tables were created the browser table was renamed
to miscellaneous except the actual rename patch was never applied,
this fixes that situation.
The generic bitmap handlers provided by each frontend are called back
from the core and therefore should be in an operation table. This was
one of the very few remaining interfaces stopping the core code from
being split into a library.
This removes the global PDF_Password interface that had completely
bitrotted and moves it into the standard misc operation table with a
sensible defualt implementation.
This also cleans up and fixes the gtk frontend implementation of the
pdf password callback so it compiles.
Finally this moves the implementation to a sensible place alongside
the other exporters reducing target makefile complexity futher.
This rationalises the path construction and basename file
operations. The default implementation is POSIX which works for all
frontends except windows, riscos and amiga which have differeing path
separators and rules.
These implementations are significantly more robust than the previous
nine implementations and also do not use unsafe strncpy or buffers
with arbitrary length limits.
These implementations also carry full documentation comments.
