95100344d3 fix runtime stack overflow bug that gri ran into:
160 - 75 was just barely not enough for deferproc + morestack.

added enum names and bumped to 256 - 128.
added explanation.

changed a few mal() (garbage-collected) to
malloc()/free() (manually collected).

61590c4c44 disallow P.t for lowercase t and not our package P.
implement hiding lowercase methods m in
signatures by adding in a hash of the package name
to the type hash code.

remove remaining checks for internally-generated _ names:
they are all gone.

1983121bbb 6g interface changes:
* allow conversion between nil interface and any type.
	* mark signatures as DUPOK so that multiple .6 can

c249a8de32 rename various magic names.
sigi and sigt:
	sys·sigi_inter -> sigi·inter
	sys·sigt_int -> sigt·int
	Package·sigt_Type -> sigt·Package.Type

	local type T in file x.go T_x -> T·x
	second one T_x_1 -> T·x·1

	method names M on T  T_M -> T·M

correctly handle local embedded types

init functions are the only place left that use underscores
