SSL.Constants: ALPN is now RFC 7301.
SSL.Constants: Added some more constants.
Override write and werror in hilfe

The overriden version uses readline->write to actually print the data.

This is rather convenient when writing asyncronous code in hilfe,
newlines are handled correctly and it interacts fairly well with the
input system.

The overriding is intentionally using add_constant to also override
debug output in modules that are loaded after hilfe is started.
Did some overhauling of the Gdbm module

o Gdbm.gdbm is now known as Gdbm.DB
o Added support for iteration over gdbm objects
o Added overloading of _m_delete, _indices and _values.
o Added some more documentation
Avoid dropping the toplevel operator documentation.

Also, changed format for getters/setters somewhat.
Fixed autodoc syntax error
Removed a few non-existing overloaded operators
Moved a few modules around in the traditional refdoc

We really should update this file completely, I think
Changes to CHANGES
Use variant to support multiple constructors. Serialize correctly. Added more protected. Removed some 8bit strings.
Added more protected.
Don't call cast directly.
Returning UNDEFINED from cast() now produces an exception.
Make illegal casts throw exception.
Only give the basic type names to cast() to avoid post processing in cast().
Added a few more global variable opcodes.

Gotta catch em all!

This time:

 PRIVATE_IF_DIRECT_GLOBAL and ASSIGN_PRIVATE_IF_DIRECT_GLOBAL

These will fetch or assign a global variable if the currently
executing program is the program the object is cloned from.

These are only slightly slower than the F_PRIVATE_GLOBAL family of
opcodes, and the overhead if the global is not actually private is
minimal.

Missing: [ASSIGN_]PRIVATE_IF_DIRECT_TYPED_GLOBAL[_AND_POP] and
ASSIGN_PRIVATE_IF_DIRECT_GLOBAL_AND_POP.
Added INC,ADD, DEC and SUBTRACT

These are inlined when both arguments are integers.

It would be fairly to do for floats as well.

DIV/MOD/AND/MULT etc would be fairly easy to add as well, but
most require some more decoding of the intel instruction
reference manual.
