Introduce assert-equal-helper for more usable mismatch reports.
Use #:gensyms instead of :keywords in tests/pkgdcl.
Add two utilities. Export assert-equal-helper from qtest.
Improve error output for tests/binary-encoding.
Make tests/basic-types work with dimitri's new my-packet-stream thingie.
Fixes to read-N-bytes functions and compiler-macro.
Rename string to octets and byte to octet everywhere that is appropriate.
This makes it less confusing for a Lisp hacker,
because a Lisp byte need not be an MySQL byte, but an octet is;
and a Lisp string is very different from a MySQL string, which is octets.
Fix regression tests, find a bug (1-octet integer failed to handle signed).
