Previously Eina_Stringshare printf variant where returning NULL with ("%s", ""). This
is highly disturbing as you would have gotten "(null)", if you asked for ("s", NULL).
To clarify and make things logical, we now return "".
Being annoyed by different types of eina critical macros - CRI, CRIT,
CRITICAL -, I concluded to unify them to one. Discussed on IRC and
finally, CRI was chosen to meet the consistency with other macros -
ERR, WRN, INF, DBG - in terms of the number of characters.
If there is any missing bits, please let me know.
Subject: [E-devel] 2 steps eina_share_common_del speed up
builtin node is never unlinked even if empty, always is the last of the queue,
so that it can be used to get a pointer to head.
cost: never unlink or promote builtin node.
benefit: no need to hash and search rbtree to unlink an empty node,
only to remove an empty head.
store full hash in Eina_Share_Common_Head, so we only hash once
use 8 lower bits as node hash, use next 8 bits as bucket index.
cost: have to apply 0xFF mask on hash in rbtree callbacks.
benefit: no need to hash when removing an empty head.
