Crypto.DSA -> Crypto.DSA.State
These softcasts generated "is noop" warning
Postgres: fix one more literal_X_string issue
Describe some of the lfun methods more intuitively

As an example, _indices() -> indices(type arg)
Include the documentation for create, if any, in the class documentation
Added missing space.
decode_value: Removed some dead code.

The macros getdata() and getdata3() are no more.
Compiler: Added low_is_variant_dispatcher().

This function is useful when you have an identifier that might be a
variant dispatcher, but you don't know of a corresponding reference.
encode_value: Don't regard the variant dispatcher as a CFUN.

The variant dispatcher is a CFUN that may show up in pure Pike
programs, so don't fallback to the C-program encodings when
the only CFUN is the variant dispatcher.

Potentially fixes dumping problems with Crypto.RSA.State
(where generate_key() is a variant function).
encode_value: Improved support for variant functions.

Variant functions weren't dumped correctly if they were
overloading inherited non-variant functions.

Fixes remaining issue with the dumping of Crypto.RSA.State.
Image.Freetype: allow use of faces beyond position 0 in font files.
