(struct gpgme_data): Remove pending filed and introduce inbound and
outbound fields.
* src/conversion.c (_gpgme_wipememory): New. Taken from GnuPG.

* src/data.h (BUFFER_SIZE): Increase to 4096 for Windows.

This brings it in line to the PIPE_BUF size on desktop Linux
systems. This should increase performance when working with
large files on Windows a bit.

This is a best effort feature to not output plaintext after a
decryption failure (e.g. due to no or broken authenticated
encryption). It always work when using a memory object and reading it
after the decryption but it can't work reliable when the user is
reading from the data object while the decryption process is still
running.
This is quite a large change because the data objects and the context
objects are allowed to be owned by different threads. Thus a
synchronization is needed and we do this with a global table of all
data objects to which the context objects can do soft-linking via a
unique data object serial number.

* src/gpgme.h.in (gpgme_data_new_from_estream): New.
* src/data-estream.c: New.
* src/data.h (gpgme_data): New union member e_stream.
--
The estream functions (gpgrt_fopen et al.) are any waypart of the
required libgpg-error library and thus it makes sense to provide this
convenience interface.
