Revert "Added 'oom' lang-item so downstream crates don't complain about missing 'oom' symbol"
This reverts commit 7d7e3137.
When being used with
std, using the
oom lang item would cause a compile error. It may be better to leave this to the downstream crates.
A good idea may be to remove all references to this function within this crate and instead call
alloc::alloc::handle_alloc_error() or just return an error.
