 * @param opts A bitfield indicating various options related to PE header

 *                               info
 *              - DBG_PRINT_INFO - Print debug information about the

 *                                 called multiple times for a given PE,

 *                                 same info each time.
 *              - EXTRACT_VINFO - Parse the PEs VERSION_INFO metadata
 *                                and store it in peinfo->vinfo
 *              - STRICT_ON_PE_ERRORS - If specified, some cases that
 *                                      might be considered a broken
 *                                      executable cause RET_BROKEN_PE
 *                                      to be returned, but otherwise
 *                                      these will be tolerated.
 *              - REMOVE_MISSING_SECTIONS - If a section exists outside of the
 *                                          file, remove it from
 *                                          peinfo->sections. Otherwise, the
 *                                          rsz is just set to 0 for it.
 * @param ctx The overaching cli_ctx.  This is required with certain opts, but
 *            optional otherwise.
 * @return If the PE header is parsed successfully, CLI_PEHEADER_RET_SUCCESS
 *         is returned. If it seems like the PE is broken,
 *         CLI_PEHEADER_RET_BROKEN_PE is returned.  Otherwise, one of the
 *         other error codes is returned.
 *         The caller MUST destroy peinfo, regardless of what this function
 *         returns.
 *
 * TODO What constitutes a "broken PE" seems somewhat arbitrary in places.
 * I think a PE should only be considered broken if it will not run on
 * any version of Windows.  We should invest more time to ensure that our
 * broken PE detection more closely aligns with this.
 *
 * TODO Simplify and get rid of CLI_PEHEADER_OPT_STRICT_ON_PE_ERRORS if
 * possible.  We should either fail always or ignore always, IMO.
 *
 * TODO Simplify and get rid of CLI_PEHEADER_OPT_REMOVE_MISSING_SECTIONS if
 * possible.  I don't think it makes sense to have pieces of the code work
 * off of incomplete representations of the sections (for instance, I wonder
 * if this makes any of the bytecode APIs return unexpected values).  This
 * appears to have been implemented to prevent ClamAV from crashing, though,
 * (bb11155) so we need to ensure the underlying issues are addressed.
 *
 * TODO Consolidate when information about the PE is printed (after successful
 * PE parsing).  This will allow us to simplify the code.  Some fail cases,
 * then, will cause PE info to not be printed at all, but I think this is
 * acceptable.  The debug messages generated in the fail cases should point to
 * what happened, and that's enough to track down the cause of any issues.
 *
 * TODO Same as above but with JSON creation
