/*
** _bucket_get
**
**
Get the bucket item with the matching key
**
Search a bucket for a given key.
**
** Arguments: self The bucket
** key The key to match against
** has_key Just return object "1" if key found, object "0" if not
** Arguments
** self The bucket
** keyarg The key to look for
** has_key Boolean; if true, return a true/false result; else return
** the value associated with the key.
**
** Returns: object matching object or 0/1 object
** Return
** If has_key:
** Returns the Python int 0 if the key is absent, else returns
** has_key itself as a Python int. A BTree caller generally passes
** the depth of the bucket for has_key, so a true result returns
** the bucket depth then.
** Note that has_key should be tree when searching set buckets.
** If not has_key:
** If the key is present, returns the associated value, and the
** caller owns the reference. Else returns NULL and sets KeyError.
** Whether or not has_key:
** If a comparison sets an exception, returns NULL.
