Signature support: separate pkcs7 specifics into a separate file.

Previously, pdf-pkcs7.c contained mishmash of functions required
for creating and checking signatures, with no separation between
the parts relating to pdf and those relating to pkcs7. This
commit introduces pdf_signature.c which contains the pdf
specifics, leaving pdf-pkcs7.c to be purely pkcs7 functions.
This should more easily allow the use of pkcs7 solutions other
than openssl. The pkcs7 api is declared in pdf-pkcs7.h. It is
entirely free of mupdf specifics, other than using an fz_stream
to specify the bytes to be hashed.
