I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
As described by Carsten in his email to edev ML titled:
"[E-devel] eo stability - i think we need to postpone that"
with the switch to Eo2 we significantly increased our usage of RW memory
pages, and thus significantly increased our memory usage when running
multiple applications.
The problem was that during the migration to Eo2 the op id cache and the
op description arrays were merged, causing the op description arrays to
no longer be RO. This patch enables users of Eo (mainly Eolian) to
declare those arrays as const (RO) again, saving that memory.
There might be performance implications with this patch. I had to remove
the op desc array sorting, and I used a hash table for the lookup. I
think the op desc sorting doesn't really affect performance because that
array is seldom accessed and is usually pretty short. The hash table
is not a problem either, because it's behind the scenes, so it can be
changed to a more efficient data structure if the hash table is not good
enough. The hash table itself is also rarely accessed, so it's mostly
about memory.
Please keep an eye for any bugs, performance or excessive memory usage.
I believe this should be better on all fronts.
This commit *BREAKS ABI*.
