[rfc][icedtea-web] Fix many memory leaks due to utf8fromidentifier misuse

[Adam Domurad]

Hi all. Every single occurrence of utf8fromidentifier requires a call to 
'memfree' after being used. This patch addresses this (there were around 
40 occurrences).

Some minor refactoring was bundled, sorry. It is hard not to bundle 
clean-up to avoid making a mess.

Most notably name->name_id in many places, to allow for use of 'name' to 
hold the actual string. As well string fiddling was reduced in some places.

A minor test is included in the changeset.

ChangeLog:
