Replace usages of B_FILE_NOT_FOUND in public-facing APIs.
As BeOS R5 had deprecated this error code, this should in theory
not cause any particular problems.

runtime_loader: fix crash because of missing initialization
The "versions" table is populated from two sources: the elf
"needed_version" and "version_definitions" tables. Both populate
specific index in the version table. Each index has an hash, and one or
two strings.
The algorithm to find data in this table is to compare by hash, and then
do an strcmp on the strings when the hash matches.
However, nothing guarantees that all the indices in the version array
will be used. Indeed, libavutil does not use the first two. These were
left uninitialized.
It could happen that one of these would accidentally have its hash equal
to one of the actual hashes we need to lookup, and invalid string
pointers. This would of course lead to a crash. This was reproductible
easily with WebKit when loading the fmpeg add-on. I guess that hit just
the right allocation/deallocation pattern to make the runtime_loader
reuse memory from a block where it had previously stored the same hash.
Anyway, just clear the whole version table after allocating, so that
unused entries have an hash of 0 and NULL string pointers, this way they
can't accidentally trigger a hash collision and crash everything.

Changed runtime_loader to use elf_* typedefs over Elf32_*.
This means that it will be using ELF64 types on x86_64 rather than
ELF32. The next step for supporting x86_64 is to implement relocations.
