/* Read in the relocs for the specified section and internalize them.
 
 
 
   The implementation is loosely based on the SOM code and made up
 
   of 3 distinct phases:
 
 
 
   1. When the VMS object is opened and parsed, the number and the size
 
      of the relocations are computed for all sections.  This makes it
 
      possible to know upfront both which sections have no relocs and
 
      the size of the reloc buffers for the other sections, at virtually
 
      no cost for consumers that don't care about relocs at all.
 
 
 
   2. When vms_slurp_reloc_table is invoked for the first time on a section
 
      with relocs, the object is traversed and all the reloc information
 
      is saved in per-section reloc buffers.  It would be very inefficient
 
      to scan the whole file on each invocation, so we slurp for all the
 
      sections at once.
 
 
 
   3. On subsequent invocations of vms_slurp_reloc_table, the relocs for the
 
      specified section are fetched from the buffer, decoded and internalized.
 
      The buffer is then freed since the internalized relocs are attached to
 
      the section, turning additional invocations of vms_slurp_reloc_table
 
      on the same section into no-ops.
 
 
 
   Since VMS objects have very few sections, it could be profitable to merge
 
   phase #2 and phase #3, i.e. to decode and internalize the relocs for all
 
   the sections at once.  The current implementation is more elegant.  */
