/* 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. */
