[PATCH?] string_transcode

During chasing the GC bugs one of my patches turned off DOD/GC in 
string_transcode (which is called from e.g string_compare).
There is no need to keep this as the GC issues seem to be solved now.

OTOH e.g. hash.c could profit from the current status, because, when 
string_compare->string_transcode doesn't run GC, various pointers in 
hash.c wouldn't be invalidated.

If we keep disabling DOD/GC in string_transcode some comments need updating.
