translates various data structures from their 32-bit class
file representations to their memory representations;
provides the inverse.
elf64_xlatetom and elf64_xlatetof provide the same
functionality for 64-bit class files.
This conversion is particularly important for cross

descriptor, which the translation routines use as follows.
Both the source and destination must have valid buffer pointers.
This member's value specifies the type of
the data to which d_buf points and the type of
data to be created in the destination.
The program supplies a d_type value in the source;
the library sets the destination's d_type to the same value.
These values are summarized below.
This member holds the total size, in bytes, of the
memory occupied by the source data and the
size allocated for the destination data.
If the destination buffer is not large enough,
the routines do not change its original contents.
The translation routines reset the destination's d_size
member to the actual size required, after the translation occurs.
The source and destination sizes may differ.
This member holds version number of the objects (desired) in the buffer.
The source and destination versions are independent.
Translation routines allow the source and destination buffers
That is, dst->d_buf may equal src->d_buf.
Other cases where the source and destination buffers overlap
give undefined behavior.
