* https://bugs.g10code.com/gnupg/issue1179
* This bug has resurfaced several times in GnuPG's history, and as far as I've
understood it, it is due to a generation or an attempt at parsing a .gpg
file (a message/file, or one of the keyrings) which is generated/formatted
such that the GnuPG data packets comprise a certain number of bytes (562
bytes precisely) and/or the demarcation signal (two equal signs, '==') of
the trailing ctb (I assume 'ctb' stands for cipher text bytes; it's
everywhere in GnuPG's sourcecode) CRC checksum ends up on its own line, like
so:

-----END PGP MESSAGE-----
When this happens, GnuPG *stops* parsing entirely before the CRC checksum
following the '==', and thus the next time it starts parsing again the
first thing it gets is the end header '-----END PGP MESSAGE-----'.
* My solution for hacking around this is to export directly to a keyring,
which can either be one we create for this purpose, or the keyring set as
self.pubring. I do not know yet if this will affect --list-keys.
* Rearrange sets of testsuites to provide logical execution order.
* Remove unused suite() function.
* Create dynamic module loader through a unittest.TestProgram.createTest
override to take an instance of unittest.TestLoader which is created later.
